Aims

Metal and ceramic humeral head bearing surfaces are available choices in anatomical shoulder arthroplasties. Wear studies have shown superior performance of ceramic heads, however comparison of clinical outcomes according to bearing surface in total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) is limited. This study aimed to compare the rates of revision and reoperation following metal and ceramic humeral head TSA and HA using data from the National Joint Registry (NJR), which collects data from England, Wales, Northern Ireland, Isle of Man and the States of Guernsey.

Aims

Fractures of the humeral shaft represent 3% to 5% of all fractures. The most common treatment for isolated humeral diaphysis fractures in the UK is non-operative using functional bracing, which carries a low risk of complications, but is associated with a longer healing time and a greater risk of nonunion than surgery. There is an increasing trend to surgical treatment, which may lead to quicker functional recovery and lower rates of fracture nonunion than functional bracing. However, surgery carries inherent risk, including infection, bleeding, and nerve damage. The aim of this trial is to evaluate the clinical and cost-effectiveness of functional bracing compared to surgical fixation for the treatment of humeral shaft fractures.

Aims

Early large treatment effects can arise in small studies, which lessen as more data accumulate. This study aimed to retrospectively examine whether early treatment effects occurred for two multicentre orthopaedic randomized controlled trials (RCTs) and explore biases related to this.

Aims

To achieve expert clinical consensus in the delivery of hydrodilatation for the treatment of primary frozen shoulder to inform clinical practice and the design of an intervention for evaluation.

Aims

There has been an increasing use of early operative fixation for scaphoid fractures, despite uncertain evidence. We conducted a meta-analysis to evaluate up-to-date evidence from randomized controlled trials (RCTs), comparing the effectiveness of the operative and nonoperative treatment of undisplaced and minimally displaced (≤ 2 mm displacement) scaphoid fractures.

Aims

The aim of this study was to investigate the outcome of periprosthetic fractures of the humerus and to assess the uniformity of the classifications used for these fractures (including those around elbow and/or shoulder arthroplasties) by performing a systematic review of the literature.

Aims

The main objective of this study was to examine whether the Oxford Shoulder Score (OSS) demonstrated floor or ceiling effects when used to measure outcomes following shoulder arthroplasty in a large national cohort. Secondary objectives were to assess its pain and function subscales, and to identify independent predictors for patients achieving a postoperative ceiling score following shoulder arthroplasty.

Aims

This systematic review places a recently completed multicentre randomized controlled trial (RCT), UK FROST, in the context of existing randomized evidence for the management of primary frozen shoulder. UK FROST compared the effectiveness of pre-specified physiotherapy techniques with a steroid injection (PTSI), manipulation under anaesthesia (MUA) with a steroid injection, and arthroscopic capsular release (ACR). This review updates a 2012 review focusing on the effectiveness of MUA, ACR, hydrodilatation, and PTSI.

Aims

A pragmatic multicentre randomized controlled trial, UK FROzen Shoulder Trial (UK FROST), was conducted in the UK NHS comparing the cost-effectiveness of commonly used treatments for adults with primary frozen shoulder in secondary care.

Aims

The aim of the Scaphoid Waist Internal Fixation for Fractures Trial (SWIFFT) was to determine the optimal treatment for adults with a bicortical undisplaced or minimally displaced fracture of the waist of the scaphoid, comparing early surgical fixation with initial cast immobilization, with immediate fixation being offered to patients with nonunion.

Background

Few studies have compared aspirin with DOACs (direct oral anticoagulants = direct thrombin inhibitors and factor Xa inhibitors) for venous thromboembolism (VTE) prophylaxis following total hip and knee replacement (THR and TKR). We assessed the efficacy and safety of aspirin compared with DOACs for VTE prophylaxis following THR and TKR using the world's largest joint replacement registry.

Aims

The aim of this study was to explore whether time to surgery affects functional outcome in displaced proximal humeral fractures

Aims

The aim of this study was to compare the clinical effectiveness of Kirschner wire (K-wire) fixation with locking-plate fixation for patients with a dorsally displaced fracture of the distal radius in the five years after injury.

Objectives

To explore whether orthopaedic surgeons have adopted the Proximal Fracture of the Humerus: Evaluation by Randomisation (PROFHER) trial results routinely into clinical practice.

Aims

The PROximal Fracture of the Humerus Evaluation by Randomisation (PROFHER) randomised clinical trial compared the operative and non-operative treatment of adults with a displaced fracture of the proximal humerus involving the surgical neck. The aim of this study was to determine the long-term treatment effects beyond the two-year follow-up.

Objectives

Accurate characterisation of fractures is essential in fracture management trials. However, this is often hampered by poor inter-observer agreement. This article describes the practicalities of defining the fracture population, based on the Neer classification, within a pragmatic multicentre randomised controlled trial in which surgical treatment was compared with non-surgical treatment in adults with displaced fractures of the proximal humerus involving the surgical neck.

Aims

A pragmatic multicentre randomised controlled trial (PROFHER) was conducted in United Kingdom National Health Service (NHS) hospitals to evaluate the clinical effectiveness and cost effectiveness of surgery compared with non-surgical treatment for displaced fractures of the proximal humerus involving the surgical neck in adults.

We present an economic evaluation using data from the Distal Radius Acute Fracture Fixation Trial (DRAFFT) to compare the relative cost effectiveness of percutaneous Kirschner wire (K-wire) fixation and volar locking-plate fixation for patients with dorsally-displaced fractures of the distal radius.

The cost effectiveness analysis (cost per quality-adjusted life year; QALY) was derived from a multi-centre, two-arm, parallel group, assessor-blind, randomised controlled trial which took place in 18 trauma centres in the United Kingdom. Data from 460 patients were available for analysis, which includes both a National Health Service cost perspective including costs of surgery, implants and healthcare resource use over a 12-month period after surgery, and a societal perspective, which includes the cost of time off work and the need for additional private care.

There was only a small difference in QALYs gained for patients treated with locking-plate fixation over those treated with K-wires. At a mean additional cost of £714 (95% confidence interval 588 to 865) per patient, locking-plate fixation presented an incremental cost effectiveness ratio (ICER) of £89 322 per QALY within the first 12 months of treatment. Sensitivity analyses were undertaken to assess the ICER of locking-plate fixation compared with K-wires. These were greater than £30 000.

Compared with locking-plate fixation, K-wire fixation is a ‘cost saving’ intervention, with similar health benefits.

Trauma and orthopaedics is the largest of the surgical specialties and yet attracts a disproportionately small fraction of available national and international funding for health research. With the burden of musculoskeletal disease increasing, high-quality research is required to improve the evidence base for orthopaedic practice. Using the current research landscape in the United Kingdom as an example, but also addressing the international perspective, we highlight the issues surrounding poor levels of research funding in trauma and orthopaedics and indicate avenues for improving the impact and success of surgical musculoskeletal research.

Objectives

A rigorous approach to developing, delivering and documenting rehabilitation within randomised controlled trials of surgical interventions is required to underpin the generation of reliable and usable evidence. This article describes the key processes used to ensure provision of good quality and comparable rehabilitation to all participants of a multi-centre randomised controlled trial comparing surgery with conservative treatment of proximal humeral fractures in adults.

The aim of this study was to review the role of clinical trial networks in orthopaedic surgery. A total of two electronic databases (MEDLINE and EMBASE) were searched from inception to September 2013 with no language restrictions. Articles related to randomised controlled trials (RCTs), research networks and orthopaedic research, were identified and reviewed. The usefulness of trainee-led research collaborations is reported and our knowledge of current clinical trial infrastructure further supplements the review. Searching yielded 818 titles and abstracts, of which 12 were suitable for this review. Results are summarised and presented narratively under the following headings: 1) identifying clinically relevant research questions; 2) education and training; 3) conduct of multicentre RCTs and 4) dissemination and adoption of trial results. This review confirms growing international awareness of the important role research networks play in supporting trials in orthopaedic surgery. Multidisciplinary collaboration and adequate investment in trial infrastructure are crucial for successful delivery of RCTs.

The peer review process for the evaluation of manuscripts for publication needs to be better understood by the orthopaedic community. Improving the degree of transparency surrounding the review process and educating orthopaedic surgeons on how to improve their manuscripts for submission will help improve both the review procedure and resultant feedback, with an increase in the quality of the subsequent publications. This article seeks to clarify the peer review process and suggest simple ways in which the quality of submissions can be improved to maximise publication success.

Background

Accurate and reproducible radiological assessment of shoulder replacement prostheses over time is important for identifying failure or to provide reassurance. A number of clearly defined radiological parameters have been described to help standardise the radiological assessment of prostheses. To our knowledge, this is the first study conducted to test the reproducibility and reliability of these measurements.

Background

A recent Cochrane review has shown that total shoulder arthroplasty (TSA) seems to offer an advantage in terms of shoulder function over hemiarthroplasty, with no other obvious clinical benefits. This is the first study to compare complication rates on a national scale.

Background

In 2011 20% of intracapsular fractured neck of femurs were treated with an uncemented hemiarthroplasty in the English NHS. National guidelines recommend cemented implants, based on evidence of less pain, better mobility and lower costs. We aimed to compare complications following cemented and uncemented hemiarthroplasty using the national hospital episode statistics (HES) database in England.

Prevalence of rotator cuff tears increases with advancing age (Ellman et al). In spite of proximal humeral fractures being common in the elderly, the influence of a coexistent rotator cuff tear on outcome has, to our knowledge, not been previously investigated. This study prospectively assessed whether the presence of a rotator cuff tear in association with a proximal humeral fracture influences functional prognosis.

85 patients treated conservatively for proximal humeral fractures were evaluated prospectively with Ultrasonography to determine the status of the rotator cuff. Every patient was managed by immobilisation of the arm in a sling for two weeks followed by a course of physiotherapy based on the Neer regime. Functional outcome was measured using the Constant shoulder score and the Oxford shoulder score, at 3-months and 12-months post injury.

Sixty-six of the 85 patients were female. The fractures were equally distributed for hand dominance. There were 27 patients with an undisplaced fracture, 34 patients with Neer's Type II fracture and 24 patients with Neer's Type III and IV fracture. There were 43 patients with full thickness cuff tears and 42 patients with no cuff tear or a partial thickness tear. Full thickness cuff tears were much more frequent in the over 60 year age group, which is consistent with the known increased incidence of cuff tears with increasing age.

The outcome scores at 3 and 12 months showed no statistically significant difference for either the Constant score or the Oxford score with regards to cuff integrity. Analysis of these scores showed no correlation between presence or absence of a full thickness cuff tear and shoulder function

The results of this study indicate that rotator cuff integrity is not a predictor of shoulder function at 12 months following proximal humeral fracture, as measured by outcome scores. This suggests that there is therefore no clinical indication for routine imaging of the rotator cuff in patients for whom conservative management is the preferred treatment option.

Multicentre clinical trials in trauma care are gaining prominence as a means of generating good-quality evidence to inform and influence clinical practice. We believe multicentre trials have an important role to play in supporting evidence-based practice, and further investment in such trials is justified.

Compression and absolute stability are important in the management of intra-articular fractures. We compared tension band wiring with plate fixation for the treatment of fractures of the olecranon by measuring compression within the fracture. Identical transverse fractures were created in models of the ulna. Tension band wires were applied to ten fractures and ten were fixed with Acumed plates. Compression was measured using a Tekscan force transducer within the fracture gap. Dynamic testing was carried out by reproducing cyclical contraction of the triceps of 20 N and of the brachialis of 10 N. Both methods were tested on each sample. Paired t-tests compared overall compression and compression at the articular side of the fracture.

The mean compression for plating was 819 N (sd 602, 95% confidence interval (CI)) and for tension band wiring was 77 N (sd 19, 95% CI) (p = 0.039). The mean compression on the articular side of the fracture for plating was 343 N (sd 276, 95% CI) and for tension band wiring was 1 N (sd 2, 95% CI) (p = 0.038).

During simulated movements, the mean compression was reduced in both groups, with tension band wiring at −14 N (sd 7) and for plating −173 N (sd 32). No increase in compression on the articular side was detected in the tension band wiring group.

Pre-contoured plates provide significantly greater compression than tension bands in the treatment of transverse fractures of the olecranon, both over the whole fracture and specifically at the articular side of the fracture. In tension band wiring the overall compression was reduced and articular compression remained negligible during simulated contraction of the triceps, challenging the tension band principle.

Large and massive rotator cuff tears can cause persistent pain and significant disability. These tears are often chronic with substantial degeneration of the involved tendons. Surgical treatment is challenging and the functional outcome after repair less predictable then for smaller tears. The aim of this study was to determine the functional outcome and rate of re-rupture after mini-open repair of symptomatic large and massive rotator cuff tears using a modified two-row technique.

Twenty-four patients, who were operated on under the care of a single surgeon between 2003 and 2006, were included in this study. Patients were assessed prospectively before and at a mean of 27 months after surgery using Constant Score and Oxford Shoulder Score. This assessment was carried out by an independent physiotherapist specialising in shoulder rehabilitation. At follow-up an ultrasound was carried out by a musculoskeletal radiographer to determine the integrity of the rotator cuff repair. Patient satisfaction was assessed using a simple questionnaire.

The mean Constant Score improved significantly from 36 preoperatively to 68 postoperatively (p< 0.0001), the mean Oxford Shoulder Score from 39 to 20 (p< 0.0001). Four patients (16.7%) had a re-rupture diagnosed by ultrasound. 87.5% of patients were satisfied with the outcome of their surgery. Tear size and repair integrity did not significantly influence functional outcome. 87.5% of patients were satisfied or very satisfied with the outcome of their surgery.

This study shows that the two-row repair of large and massive rotator cuff tears using a mini-open approach is an effective method of repair with a comparatively low re-rupture rate. It significantly improves the functional outcome and leads to a very high patient satisfaction. We conclude that these results justify repair of large to massive rotator cuff tears when possible, irrespective of chronicity of symptoms.

The 2010 Fellows undertook a six-week journey through centres of orthopaedic excellence along the East Coast of Canada and the United States. What we learned and gained from the experience and each other is immeasurable, but five areas particularly stand out; education, research, service delivery, financial insights and professional development.

There are many types of treatment used to manage the frozen shoulder, but there is no consensus on how best to manage patients with this painful and debilitating condition. We conducted a review of the evidence of the effectiveness of interventions used to manage primary frozen shoulder using the Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effects, the Physiotherapy Evidence Database, MEDLINE and EMBASE without language or date restrictions up to April 2009. Two authors independently applied selection criteria and assessed the quality of systematic reviews using the Assessment of Multiple Systematic Reviews (AMSTAR) tool. Data were synthesised narratively, with emphasis placed on assessing the quality of evidence.

In total, 758 titles and abstracts were identified and screened, which resulted in the inclusion of 11 systematic reviews. Although these met most of the AMSTAR quality criteria, there was insufficient evidence to draw firm conclusions about the effectiveness of treatments commonly used to manage a frozen shoulder. This was mostly due to poor methodological quality and small sample size in primary studies included in the reviews. We found no reviews evaluating surgical interventions.

More rigorous randomised trials are needed to evaluate the treatments used for frozen shoulder.

Low-energy fractures of the proximal humerus indicate osteoporosis and it is important to direct treatment to this group of patients who are at high risk of further fracture. Data were prospectively collected from 79 patients (11 men, 68 women) with a mean age of 69 years (55 to 86) with fractures of the proximal humerus in order to determine if current guidelines on the measurement of the bone mineral density at the hip and lumbar spine were adequate to stratify the risk and to guide the treatment of osteoporosis. Bone mineral density measurements were made by dual-energy x-ray absorptiometry at the proximal femur, lumbar spine (L2-4) and contralateral distal radius, and the T-scores were generated for comparison. Data were also collected on the use of steroids, smoking, the use of alcohol, hand dominance and comorbidity.

The mean T-score for the distal radius was −2.97 (sd 1.56) compared with −1.61 (sd 1.62) for the lumbar spine and −1.78 (sd 1.33) for the femur. There was a significant difference between the mean lumbar and radial T scores (1.36 (1.03 to 1.68); p < 0.001) and between the mean femoral and radial T-scores (1.18 (0.92 to 1.44); p < 0.001). The inclusion of all three sites in the determination of the T-score increased the sensitivity to 66% compared with that of 46% when only the proximal femur and lumbar spine were used. This difference between measurements in the upper limb compared with the axial skeleton and lower limb suggests that basing risk assessment and treatment on only the bone mineral density taken at the hip or lumbar spine may misrepresent the extent of osteoporosis in the upper limb and the subsequent risk of fracture at this site.

The assessment of osteoporosis must include measurement of the bone mineral density at the distal radius to avoid underestimation of osteoporosis in the upper limb.

Introduction: The surgical management of proximal humeral fractures continues to be an unsolved problem for the orthopaedic surgeon. Disagreement remains over how best to fix the more challenging complex fractures in younger patients where the ultimate goals of treatment are restoration of a painless shoulder, adequate function, and preservation of humeral head viability.

The PHILOS plate attempts to improve on previously designed implants by preserving the biological integrity of the humeral head articular fragment. The minimally invasive technique minimises soft tissue damage whilst at the same time securing the reduction using multiple locking screws with angular stability, thus allowing early mobilisation.

Methods: Retrospective review of the notes and x-ray images of 54 fractures treated with the PHILOS plate between Jan 2000 and Aug 2005. Data including baseline demographics, the presence of any complications and the need for reoperation were collected. In addition 43 (81%) patients were contacted and Oxford (OSS) and Disabilities of the Arm, Shoulder and Hand (DASH) scores were calculated to assess functional recovery. All patients were contacted at a minimum of 6 months following fixation with an average follow up of 18 months (Range 6–41 months)

We also present a cost analysis relating to the use of the PHILOS plate in practice.

Results: 54 fractures in 53 patients (25F:28M). Average age 54.4. There were 26 2-part, 15 3-part and 13 4-part fractures. A total of 11 (20%) patients had complications of which 7 (13%) required reoperation. These complications included deep infection (3 cases), AVN (4), Non Union (3) and plate impingement (1).

Mean OSS and DASH at follow up were 24.8 (S.D 11.6) and 28.0 (S.D 26.9) respectively. Worse scores were seen in those patients who had complications (OSS 39.4 Vs 22.6, DASH 58.2 Vs 23.4) although this difference was not statistically significant. There was also a trend for poorer scores with increasing fracture complexity and better scores in those patients operated upon by surgeons with a specific interest in the upper limb and in patients whose surgeon had performed more than 5 fixations.

Conclusion: Our series reports a much higher complication rate (20%) than that previously published. Whilst those patients who do not suffer complications reported good functional outcomes the presence of postoperative complications was associated with poorer results. Outcomes following surgery were affected by patient, implant and surgeon related factors. Given the high rate of serious complications and their detrimental affect on outcome surgeons should give serious consideration to the appropriateness of using such implants. To clarify these issues, further prospective randomised trials are needed.

The aim of this study was to determine the functional outcome and rate of re-tears following mini-open repair of symptomatic large and massive tears of the rotator cuff using a two-row technique.

The 24 patients included in the study were assessed prospectively before and at a mean of 27 months (18 to 53) after surgery using the Constant and the Oxford Shoulder scores. Ultrasound examination was carried out at follow-up to determine the integrity of the repair. Patient satisfaction was assessed using a simple questionnaire.

The mean Constant score improved significantly from 36 before to 68 after operation (p < 0.0001) and the mean Oxford Shoulder score from 39 to 20 (p < 0.0001). Four of the 24 patients (17%) had a re-tear diagnosed by ultrasound. A total of 21 patients (87.5%) were satisfied with the outcome of their surgery. The repair remained intact in 20 patients (83%). However, the small number of re-tears (four patients) in the study did not allow sufficient analysis to show a difference in outcome in relation to the integrity of the repair.

Introduction: Scoring systems for assessment of shoulder function are invaluable tools in determining changes in a patient’s condition. We utilised two commonly used assessment tools in patients with conservatively treated proximal humeral fractures to establish their behaviour in this patient group.

Methods: OSS and Constant Scores were collected prospectively at 3 and 12 months post injury, for 103 consecutive patients treated conservatively for proximal humeral fractures. Comparison of the scores was undertaken by creating scattergraphs, calculating Pearson’s correlation coefficient and producing Bland and Altman plots. Sensitivity to change was calculated using paired t-tests. Linear regression analysis was finally performed to predict Constant Score from the OSS.

Results: 177 sets of scores were collected. The scores correlated well with a correlation coefficient (r) of 0.84 (p< 0.001,n=177). This relationship was equally strong at 3 (r=0.77 (p< 0.001,n=94)) and 12 months (r=0.87 (p< 0.001,n=83)) and demonstrated a clear relationship between the scoring systems. Bland and Altman plots showed good agreement between the scores. Both scores were sensitive to change over time (OSS (t(81)=6.14,p< 0.001), Constant (t(80)=−10.27,p< 0.001)). Regression analysis produced a regression equation (R2=0.70) of: Constant Score=99.3-(1.67 times OSS). This level of model fit was statistically significant (F(1,175)=412.8,(p< 0.001))

Conclusion: This study provides information about the behaviour of two frequently used functional scoring systems in patients with proximal humeral fractures. Based on our finding we feel that these scores are appropriate assessment tools in these patients. The OSS may also be considered as an alternative for assessing longer term follow up as, being solely subjective, it is easier to administer and correlates well with the Constant Score.

Upper gastrointestinal (GI) bleeding in patients who undergo hip and knee arthroplasty tends to be associated with NSAID use, steroid intake, pre-existing peptic ulcers and smoking. The use of Aspirin for thromboprophylaxis is an added risk for the occurrence of GI Bleed. The aim of this study was to determine if the use of peri-operative oral Ranitidine reduces the incidence of GI bleeding when Aspirin thromboprophylaxis is used for hip and knee arthroplasty.

Data from 1491 consecutive patients who underwent Hip and knee replacements at the James cook university hospital (Group 1) and 886 patients who underwent Hip and Knee replacements at the Friarage hospital, Northallerton (Group 2) was analysed to determine the incidence of Gastro intestinal Bleeding. All patients received 150 mg of Aspirin per day for a period of six weeks from the day of surgery. Additionally patients operated at the Friarage Hospital received 300 mg of oral Ranitidine per day, for three postoperative days. Patients with clinically symptomatic GI bleeding were evaluated by the Upper GI team.

We observed that patients in Group 1 had a higher incidence of overt upper GI haemorrhage (n=14), which was statistically significant (p < 0.014) compared with patients in group 2(n=1). From the pooled data of both groups, there were 18 reported patients with symptomatic pulmonary embolism (0.75%) 3 of which were fatal (0.12%), phlebitis of deep leg veins in 31 patients (1.3%), deep vein thrombosis in 34 patients (1.43%), 5 of whom had embolic episodes, post operative infection in 22 patients (1.13%), and postoperative haemorrhage in 5 patients (0.2%). Thromboembolic phenomenon and pulmonary embolism was confirmed by autopsy in the three cases.

Based on this experience, we recommend the use of peri-operative gastric protection when aspirin is used for thromboprophylaxis in hip and knee arthroplasty.

Introduction: Many authors have stated that open reduction and internal fixation of displaced ankle fractures give better results than conservative management (Hughes et al, Clin Orthop 1979; Tunturi et al, Acta Orthop Scand 1983; Philips et al, JBJS 1985 and ). However, there is little information on the long-term outcome of operated ankle fractures. There is inadequate knowledge of patient perception of ankle function following operative treatment of these injuries.

Aim: To analyse long-term results following operative treatment of these fractures using a patient centred outcome measure.

Methods: 112 patients had undergone operative fixation of isolated, closed bi-malleolar ankle fractures between 1992 and 1996 at Middlesbrough General Hospital. All patients had undergone operative fixation using standard AO principles. An independent assessor ascertained the quality of reduction using standardised radiological parameters (Joy et al JBJS 1974, Sarkisian & Cody J Trauma 1976, Mont et al J Ortop Trauma 1992) to assess the post-operative X-ray films. All postoperative reductions were within the parameters of a good reduction.

The modified Olerud & Molander ankle score questionnaire was sent by post to all patients identified living in the region.

Results: 66 out of 112 patients responded; 34 (52%) leading a sedentary lifestyle and 32 (48%) a moderate/ active lifestyle. Mean age of the patients was 47 years. The follow-up period ranged from 5 to 11 years (average 7 years).

Olerud and Molander scores ranged from 5 to 100, with a mean score of 66.5 (SD 27.6), and median score of 70. Only 9 (13.6%) patients had a score of 100. Comparisons between Olerud and Molander scores were made with regard to: gender, whether metal work was removed at a second operation, Weber classification (B vs C) and patient’s lifestyle. No significant differences were observed

The associations between Olerud and Molander score and the key variables were assessed using non-parametric (Spearman’s) correlation coefficients. None of the variables considered were significantly associated with Olerud and Molander score.

Conclusion: The study would suggest that, despite modern fixation techniques, few patients following bi-malleolar ankle fracture have a symptom free ankle. There is no obvious parameter to predict outcome in patients who are managed appropriately for these injuries.

Background: Prevalence of rotator cuff tears increases with advancing age (Ellman et al). In spite of proximal humeral fractures being common in the elderly, the influence of a coexistent rotator cuff tear on outcome has, to our knowledge, not been previously investigated.

Aim: This study assess whether the presence of a rotator cuff tear in association with a proximal humeral fracture influences prognosis.

Methods: 85 patients treated conservatively for proximal humeral fractures were evaluated prospectively with Ultrasonography to determine the status of the rotator cuff. Every patient was managed by immobilisation of the arm in a sling for three weeks followed by a course of physiotherapy based on the Neer regime. Functional outcome was measured using the Constant shoulder score and the Oxford shoulder score, at 3-months and 12-months post injury.

Results: Sixty-Six of the 85 patients were female. The fractures were equally distributed for hand dominance. There were 27 patients with an undisplaced fracture, 34 patients with Neer’s Type II fracture and 24 patients with Neer’s Type III and IV fracture. There were 43 patients with full thickness cuff tears and 42 patients with no cuff tear or a partial thickness tear. Full thickness cuff tears were much more frequent in the over 60 year age group, which is consistent with the known increased incidence of cuff tears with increasing age.

The outcome scores at 3 and 12 months showed no statistically significant difference for either the Constant score or the Oxford score with regards to cuff integrity. Analysis of these scores showed no correlation between presence or absence of a full thickness cuff tear and shoulder function

Conclusion: The results of this study indicate that rotator cuff integrity is not a predictor of shoulder function at 12 months following proximal humeral fracture, as measured by outcome scores. This suggests that there is therefore no clinical indication for routine imaging of the rotator cuff in patients for whom conservative management is the preferred treatment option.

Background: The incidence of proximal humeral fractures is increasing with time. There is continuing debate about the indications for surgical intervention for this relatively common injury. Baseline data on functional outcome is essential in order to study the effect of surgical intervention. Functional outcome scores provide reliable and valid judgments of health status and the benefits of treatment. During our preparation of a study proposal on this topic to the Health Technology Assessment Program recently, we noted the lack of such data on outcome scores in the current literature.

Aim: To assess the functional outcome using the Constant and Oxford scores in patients treated conservatively for proximal humeral fractures.

Methods: We prospectively studied 103 consecutive patients who were treated conservatively for proximal humeral fractures. Patient demographics, fracture type (Neer), hand dominance and comorbidity were recorded. Constant and Oxford shoulder scores were recorded 3 and 12 months post injury.

Results: The average Constant shoulder score for males was significantly higher (better outcome) and the Oxford shoulder score significantly lower (better outcome) as compared to females. The scores were not affected by hand dominance. Although the raw scores tended to be worse with 3 or 4 part fractures the difference in the mean scores between the various Neer fracture types did not reach convential levels of significance.

A trend towards lesser degrees of improvement in the outcome scores was noted with increasing age. The degree of improvement in the outcome scores was not affected by sex, limb dominance or fracture type (Neer’s classification).

Conclusion: This study indicates the average behaviour of the Constant and Oxford scores with conservative treatment of proximal humeral fractures. This data should help with sample size and power calculations when studying interventions for this injury. We hope that this data will provide a baseline to help inform future study designs on proximal humeral fractures.

Introduction and Aims: To determine if the surface area of partial thickness (< 50%), Bursal side tears of the cuff influence outcome following Subacromial Decompression.

Method: Shoulder function using Constant score (CS) was recorded before and a minimum of one year after Arthroscopic Subacromial Decompression (ASD) in patients undergoing surgery for primary impingement. In patients who had partial thickness, Bursal side tears (BT), the length of the tear in its largest dimension (surface area) was measured. These patients were divided into two groups according to the tear surface area (≤9 mm and ≥10mm) .To determine whether having a BT (< 50% thickness) or its surface area affect pre- and post-operative CS, t-tests were performed.

Results: 110 patients underwent ASD over a one-year period for primary impingement. Twenty-two patients with partial thickness BT and 18 patients with intact rotator cuff were included in this study. In 10 patients, the BT was ≤9 mm (mean 7 mm) and in 12 patients BT was ≥10mm (mean 13 mm).

Statistical analysis of pre- and post-operative Constant scores showed that, in ≤9 mm group CS increased significantly by 21.5, p=0.02, 95% CI (4.9, 38.1). CS increased in ≥10mm group by 22.8, p< 0.01, 95%(11.5, 34.1). Comparing the change in CS between these two groups with different tears size, there was no significant difference (2-sample t-test, t=0.15, 20df, p=0.88).

To determine whether having BT tear affects pre- and post-operative Constant scores, all BTs were grouped together and compared with the group of patients with intact cuff.

In the group with BTs, average Constant scores increased significantly (paired t-test, t=5.24, 21df, p< 0.01) by 22.2 with 95% CI (13.4, 31.0).

In the group with no tears, average Constant scores increased significantly (paired t-test, t=5.17, 17df, p< 0.01) by 26.6, 95% CI (15.8, 37.5).

Comparing the levels of absolute change in Constant scores from pre- to post-operation between the two groups there is no difference in outcome between patients with a tear and those without a tear (2-sample t-test, t=1.03, 38df, p=0.31).

Conclusion: We conclude that ASD yields satisfactory results in patients with BTs involving < 50% thickness, irrespective of the surface area of the tear.

Purpose: To analyse preliminary outcomes of a new synthetic ligament used for reconstructing coraco-clavicular ligament in acromio-clavicular joint disruption.

Methods: Patients who underwent acromio-clavicular joint stabilisation using Nottingham Surgilig were followed up at average of 40 months (range 6–80 months) post operation. Apart from clinical and radiological assessment, the Constant-Murley scoring system and the Imatani scores were also used to measure outcome.

Results: Twenty patients underwent this operation and data was available on 19 of them. These patients had their operation after an average of 18 months following injury, during which period they had conservative treatment, except in 2 cases where a Weaver Dunn operation was performed initially.

The mean Constant score was 88 (s.d. 12). The mean Imatani score was 86 (s.d. 16). Most patients were satisfied with the operation (90%). There was one case of rupture through the central portion of the Surgilig, and following extensive laboratory analysis, the ligament has been modified since. One patient had a fracture of his coracoid while lifting heavy weights. In 4 patients there was clinical and radiological evidence of loosening of the screw but only 1 complained of this being a problem.

Conclusion: This is an initial medium term outcome analysis of the Nottingham Surgilig. Our results are promising and justify further use and evaluation of this relatively new technique.

Systematic studies are required to examine the effects on outcomes of alternative treatments and surgical techniques in the management of Orthopaedic conditions. Functional outcome scores provide reliable and valid judgments of health status and benefits of the treatment. We undertook a prospective study to assess the functional outcome in patients treated conservatively for proximal humeral fractures.

103 patients treated conservatively for a proximal humeral fracture were followed prospectively. Constant shoulder score and Oxford shoulder score were recorded at 3 months and 12 months follow-up.

A trend towards lesser degrees of improvement in the outcome scores was noted with increasing age. The degree of improvement in the outcome scores was not affected by sex, limb dominance or fracture type (Neer’s classification).

This information gives a guide to average behaviour in different groups of individuals with conservative treatment for proximal humeral fractures. We could then using this data postulate what would constitute a clinically relevant difference and calculate study numbers required while assessing other form of treatments for such fractures

Aim: The prevalence of rotator cuff tears increases with advancing age. Proximal humeral fracture are also common in the elderly, but the influence of a coexistent rotator cuff tear on clinical outcome following fracture has not been previously investigated.

Method: In this study 85 patients treated conservatively for proximal humeral fractures were evaluated with ultrasonography to determine the status of the rotator cuff. Outcome was evaluated using the Constant shoulder score and Oxford shoulder score, and recorded at 3 months and 12 months follow up. The null hypothesis is that there is no correlation between the presence of absence of cuff tear following fracture and clinical outcome.

The data was analysed to determine if the presence of a full thickness rotator cuff tear influenced functional outcome in these patients.

The null hypothesis has not been disproved. There is no statistically significant difference in outcome with presence of an associated full thickness rotator cuff tear with proximal humeral fractures.

Conclusion: At present this study suggests that there is no indication for routine ultrasonography evaluation of the rotator cuff following proximal humerus fracture.

To determine if the surface area of partial thickness (< 50%), Bursal side tears of the cuff influence outcome following Subacromial Decompression.

Shoulder function using Constant score (CS) was recorded before and a minimum of one year after Arthroscopic Subacromial Decompression (ASD) in patients undergoing surgery for primary impingement. In patients who had partial thickness, Bursal side tears (BT), the length of the tear in its largest dimension (surface area) was measured. These patients were divided into two groups according to the tear surface area (≤9 mm and ≥10mm) .To determine whether having a BT (< 50% thickness) or its surface area affect pre and postoperative CS, t-tests were performed.

110 patients underwent ASD over a one-year period for primary impingement. 22 patients with partial thickness BT and18 patients with intact rotator cuff were included in this study. In 10 patients, the BTwas ≤9 mm (mean7mm) and in 12 patients BTwas ≥10mm(mean13mm). Statistical analysis of Pre-& postoperative Constant scores showed that, in ≤9 mm group CS increased significantly by 21.5, p=0.02, 95% CI (4.9, 38.1). CS increased in ≥10mm group by 22.8, p< 0.01, 95%(11.5, 34.1). Comparing the change in CS between these two groups with different tears size, there was no significant difference (2-sample t-test, t=0.15, 20df, p=0.88).

To determine whether having BT tear affects pre- and post-operative Constant scores, all BTs were grouped together and compared with the group of patients with intact cuff.

In the group with BTs, average Constant scores increased significantly (paired t-test,t=5.24,21df,p< 0.01) by 22.2 with 95% CI (13.4, 31.0). In the group with no tears, average Constant scores increased significantly (paired t-test,t=5.17,17df,p< 0.01) by 26.6, 95% CI (15.8, 37.5).

Comparing the levels of absolute change in Constant scores from pre- to post-operation between the two groups there is no difference in outcome between patients with a tear and those without a tear (2-sample t-test, t=1.03, 38df, p=0.31).

We conclude that ASD yields satisfactory results in patients with BTs involving < 50% thickness, irrespective of the surface area of the tear.

Aim: We investigated the accuracy of clinical signs for the diagnosis of rotator cuff disease.

Methods: Fifty patients with history of rotator cuff disease (subacromial impingement syndrome or rotator cuff tear) were examined by two observers to determine the accuracy of clinical tests for the condition. The observers were a consultant (cons.) with an established shoulder practice and a senior registrar (reg.) with an interest in shoulder surgery. The clinical signs evaluated include the painful arc, the drop arm test, Neer’s sign and Hawkins’ sign. For rotator cuff pathology we evaluated the strength of abduction initiation and at 90 degrees abduction for supraspinatus, Speed’s and Yergason’s tests for biceps, strength of shoulder external rotation for infraspinatus and the Gerber lift-off test for subscapularis. We compared our clinical accuracy against a positive subacromial injection test for impingement syndrome, and the findings of rotator cuff tears at arthroscopy.

Results: The consultant and the registrar did not differ significantly in their assessments (paired t-test, p> 0.05). The highly sensitive tests have poor specificity. The most sensitive tests for impingement syndrome were the Hawkins’ sign (cons: 100%, reg: 97%) and the Neer’s sign (cons: 94%, reg: 81%). The Hawkins’ sign also had high negative and positive predictive values. The painful arc and the drop arm tests both had low sensitivity and specificity. Testing the supraspinatus strength at 90 degrees abduction was more sensitive for full thickness cuff tear than testing strength of abduction initiation (cons: 100% vs 67%; reg: 90% vs 50%). These tests were poor at differentiating partial thickness tears from full thickness tears.

Conclusion: The Neer’s and Hawkins’ signs were the most sensitive for impingement syndrome. Testing the supraspinatus at 90 degrees abduction was more sensitive than abduction initiation for full thickness supraspinatus tear.

We aimed to devise a simple and reproducible method of shoulder strength measurement with reference to the Constant and Murley shoulder score.

Fifteen male and 15 female patients were tested. The average age was 32 years. None had previous shoulder pathology. We used a simple spring balance and an electronic load cell to measure force. The system was attached to the floor and connected to the patients arm with an adjustable strap. Strength was measured at 90 degrees of flexion and abduction (in the plane of the scapula), with both dominant and non-dominant limbs. The strap was placed on the upper arm a fixed distance from the tip of the acromion. In addition measurements were taken with the strap attached at the patients wrist. Measurements were repeated after a rest period.

There was no significant difference between strength measured in abduction or flexion or between dominant and non-dominant limbs. The mean measurement for females (13.38kg) is 56 of the male mean (23.92kg). The mean measurement with the strap at the wrist was 47.6 of the mean measurement with the strap on the arm for females and 56.25 for males.

In their original description Constant and Murley use the method described by Moseley to measure shoulder strength. This involved the examiner pulling down on a spring balance held at arms length by the patient. The value assigned to the scale (0.5 kg scores one point to a maximum of 25) is arbitrary. By placing the strap on the upper arm the lever arm is shortened and a higher strength measurement is obtained, the position is standardised by measuring a fixed distance from the tip of the acromion. By adjusting the scoring scale accordingly a greater margin for error and thus greater accuracy and reproducibility can be obtained. In addition there is a large difference in mean strength between males and females that is not taken into account in the Constant and Murley score. A simple multiplier could be used to correct this factor.

We suggest minor modifications to strength measurement for the Constant and Murley score could improve accuracy and reproducibility and correct scoring differences between the sexes.

We investigated the accuracy of clinical signs for the diagnosis of rotator cuff disease. Fifty patients with history suggestive of rotator cuff disease (subacromial impingement syndrome or rotator cuff tear) were examined by two observers to determine the accuracy of commonly used clinical tests for the condition. The observers were a consultant (cons.) with an established shoulder practice and a senior registrar (reg.) with an interest in shoulder surgery. The clinical signs of impingement syndrome we evaluated include the painful arc, the drop arm test, Neer’s sign and Hawkins’ sign. For rotator cuff pathology we evaluated the strength of abduction initiation and at 90 degrees abduction for supraspinatus, Speed’s and Yergason’s tests for biceps, strength of shoulder external rotation for infraspinatus and the Gerber lift-off test for subscapularis. We compared our clinical accuracy against a positive subacromial injection test for impingement syndrome, and the findings of rotator cuff tears at arthroscopy.

The consultant and the registrar did not differ significantly in their assessments (paired t-test, p> 0.05). The highly sensitive tests have poor specificity. The most sensitive tests for impingement syndrome were the Hawkins’ sign (cons:100%, reg: 97%) and the Neer’s sign (cons: 94%, reg: 81%). The Hawkins’ sign also had high negative and positive predictive values. The painful arc and the drop arm tests both had low sensitivity and specificity. Testing the supraspinatus strength at 90 degrees abduction was more sensitive for full thickness cuff tear than testing strength of abduction initiation (cons: 100% vs 67%; reg: 90% vs 50%). These tests were poor at differentiating partial thickness tears from full thickness tears.

Our findings echoed the conclusions of other papers in that the Neer’s and Hawkins’ signs are the most sensitive for impingement syndrome. Testing the supraspinatus at 90 degrees abduction was more sensitive than abduction initiation for full thickness supraspinatus tear.

A pilot study of a physiotherapy led shoulder clinic was initiated in January 1999 as a direct response to increasing orthopaedic consultant out-patient clinic waiting times.

The orthopaedic consultant reviews letters from GP’s to the orthopaedic clinic. Patients with benign musculoskeletal shoulder problems are referred to Shoulder Assessment Clinic (SHAC). The physiotherapist completes a subjective and objective assessment and a shoulder score is recorded using Constant and Murley Shoulder (Constant and Murley 1985). The scoring system has a maximum of 100 points indicating perfect, pain-free movement and function. The Constant and Murley Shoulder score remains most widely used and validated scoring system in Europe for the shoulder.

A total of 130 patients were referred to SHAC between January 1999 and December 1999. Sixty-six patients were treated and discharged by physiotherapy alone with an average increase in shoulder score of 40 points. Twenty-seven had surgery, 19 had steroid injection. Overall waiting time to be seen in SHAC was 58 days. Since this initial pilot, 320 patients have been assessed and treated in the SHAC.

Our experience of physio-led shoulder clinic shows patients can be assessed and treated with a far shortened waiting time, and the improved shoulder scores suggest effective treatment. This allows more patients of an appropriate type to be seen in the outpatient orthopaedic clinic.
