Distal radius fractures (DRF) are common and the indication for surgical treatment remain controversial in patients higher than 60 years old. The purpose of the study was to review and analyze the current evidence-based literature.

We performed a systematic review and meta-analysis according to PRISMA guidelines in order to evaluate the efficacy of volar locking plating (VLP) and conservative treatment in DRF in patients over 60 years old. Electronic databases including MEDLINE, CENTRAL, Embase, Web of science and Clinical Trial.gov were searched from inception to October 2020 for randomized controlled trials. Relevant article reference lists were also passed over.

Two reviewers independently screened and extracted the data. Main outcomes included functional status: wrist range of motion, validated scores and grip strength. Secondary outcomes include post-operative complications and radiologic assessment.

From 3009 screened citations, 5 trials (539 patients) met the inclusion criteria. All trials of this random effect meta-analysis were at moderate risk of bias due to lack of blinding. Differences in the DASH score (MD −5,91; 95% CI, −8,83; −3,00), PRWE score (MD −9.07; 95% CI, −14.57, −3.57) and grip strength (MD 5,12; 95% CI, 0,59-9,65) were statistically significant and favored VLPs. No effect was observed in terms of range of motion. Adverse events are frequent in both treatment groups, reoperation rate is higher in the VLP group.

VLP may provide better functional outcomes in patients higher than 60 years old. More RCT are still needed to evaluate if the risks and complications of VLP outweigh the benefits.

Despite the current trend favoring surgical treatment of displaced intra-articular calcaneal fractures (DIACFs), studies have not been able to demonstrate superior functional outcomes when compared to non-operative treatment. These fractures are notoriously difficult to reduce. Studies investigating surgical fixation often lack information about the quality of reduction even though it may play an important role in the success of this procedure. We wanted to establish if, amongst surgically treated DIACF, an anatomic reduction led to improved functional outcomes at 12 months.

From July 2011 to December 2020, at a level I trauma center, 84 patients with an isolated DIACF scheduled for surgical fixation with plate and screws using a lateral extensile approach were enrolled in this prospective cohort study and followed over a 12-month period. Post-operative computed tomography (CT) imaging of bilateral feet was obtained to assess surgical reduction using a combination of pre-determined parameters: Böhler's angle, calcaneal height, congruence and articular step-off of the posterior facet and calcaneocuboid (CC) joint. Reduction was judged anatomic when Böhler's angle and calcaneal height were within 20% of the contralateral foot while the posterior facet and CC joint had to be congruent with a step-off less than 2 mm. Several functional scores related to foot and ankle pathology were used to evaluate functional outcomes (American Orthopedic Foot and Ankle Score - AOFAS, Lower Extremity Functional Score - LEFS, Olerud and Molander Ankle Score - OMAS, Calcaneal Functional Scoring System - CFSS, Visual Analog Scale for pain - VAS) and were compared between anatomic and nonanatomic DIAFCs using Student's t-test. Demographic data and information about injury severity were collected for each patient.

Among the 84 enrolled patients, 6 were excluded while 11 were lost to follow-up. Thirty-nine patients had a nonanatomic reduction while 35 patients had an anatomic reduction (47%). Baseline characteristics were similar in both groups. When we compared the injury severity as defined by the Sanders’ Classification, we did not find a significant difference. In other words, the nonanatomic group did not have a greater proportion of complex fractures. Anatomically reduced DIACFs showed significantly superior results at 12 months for all but one scoring system (mean difference at 12 months: AOFAS 3.97, p = 0.12; LEFS 7.46, p = 0.003; OMAS 13.6, p = 0.002, CFSS 7.5, p = 0.037; VAS −1.53, p = 0.005). Univariate analyses did not show that smoking status, worker's compensation or body mass index were associated with functional outcomes. Moreover, fracture severity could not predict functional outcomes at 12 months

This study showed superior functional outcomes in patients with a DIACF when an anatomic reduction is achieved regardless of the injury severity.

Reported wound complication in below knee surgery can be quite high. Recent study demonstrated that increased blood loss and hematoma formation increase wound complications especially in foot and ankle surgeries. Despite the evidence on the benefit of TXA on blood loss in TKA and THA it is not routinely used by surgeon in below knee surgery.

To assess the efficacy and safety of this medication in reducing wound complication and blood loss and the risk of thromboembolic complications in patients undergoing below knee surgery. A systematic literature search of PubMed, Embase, Ovid, the Cochrane Library and AAOS and AOFAS conference proceedings was conducted. The primary outcome was the rate of wound complications. Data were analyzed using the Review Manager 5.3 software.

Nine studies involving 861 patients met the inclusion criteria. The meta-analysis indicated that TXA, when compared to a control group, reduced wound complications (OR, 0.54; 95% IC, 0.31 to 0.95, p = 0,03), blood loss (MD = −149,4 ml; 95% CI, −205,3ml to −93,6ml), post-operative drainage (MD = −169,8 ml; 95% CI, −176,7 to −162,9 ml) and hemoglobin drop (MD = −8,75 g/dL; 95% IC, −9,6 g/dL to −7,8 g/dL). There was no significant difference in thromboembolic events (RR 0,53; 95% CI, 0,15 - 1,90; p = 0,33).

This study demonstrated that TXA could be use in below knee surgery to reduce wound complication and blood loss without increased thromboembolic complications. The small number of studies limit the findings interpretation. Further studies are needed to sustain those resutls.

Worldwide, it is expected that 6.3 million patients will sustain a hip fracture in 2050. Hemiarthroplasty is commonly practiced for displaced femoral neck fractures. The choice between unipolar (UH) or bipolar (BH) hemiarthroplasty is still controversial. The objective of this study was to assess the effect on hip function of BH compared to UH for a displaced femoral neck fracture in elderly patients.

We conducted a systematic review and meta-analysis of randomized controlled trials comparing BH to UH. Data sources were Medline, Embase, Cochrane Library and Web of Science. All data was pooled in Review Manager (RevMan) version 5.3 software. Selection of the studies included, data abstraction, data synthesis, risk of biais and quality of evidence evaluation was done independently by two authors. Our primary outcome was postoperative hip function. Secondary outcomes were health-related quality of life (HRQoL), acetabular erosion and postoperative complications.

13 randomized controlled trials (n=2256) were eligible for the meta-analysis. There was no difference in hip function scores (standardized mean difference of 0.33 [−0.09–0.75, n=864, I²= 87%,]). Patients with bipolar heads had higher Health-Related Quality of Life scores than patients with unipolar heads (mean difference in EQ-5D scores of 0.12 [0.04–0.19, n=550, I²= 44%]). The use of BH decreased the incidence of acetabular erosion (relative risk of 0.37 [0.17–0.83, n=525, I²= 0%]). There was no relative risk difference for mortality, dislocation, revision and infection.

Due to the high heterogeneity between the studies included, it is still unclear whether patients undergoing BH have better hip function than patients undergoing UH. Although, health-related quality of life (HRQoL) may be improved. Future research could be conducted to determine whether a BH offers a better quality of life than UH to geriatric patients undergoing surgery. More precise assessment scores could be developed to better evaluate postoperative outcomes.

Elderly patients undergoing surgery for a hip fracture are at risk of thromboembolic events (TEV). The risk of TEV is now rare due to thromboprophylaxis. However, hip fracture treatment has evolved over the last decade. The risk of TEV may have been modified. The objective of this study was to determine the risk of symptomatic TEV following surgery for a hip fracture, in an elderly population.

Retrospective cohort study of all patients > 65 years old undergoing surgery for a femoral neck or intertrochanteric hip fracture in two academic centers, between January 1st 2008 and January 1st 2019. The follow-up was fixed at 3 months. The cumulated risk of thromboembolic events was calculated using the Kaplan-Meier estimator and a predictive logistic regression model was used to determine risk factors.

3265 patients were eligible for analysis. The mean age was 83.3 ±8.1 years old and 75.6% of patients were female. The mortality was 7.55% (N=112) at 3 months. 98.53% of this cohort received thromboprophylaxis. The cumulated risk for a thromboembolic event was 3.55% at 1 month and 6.41% at 3 months (N=99). There were 9 fatal pulmonary embolisms. 89.19% thromboembolic events occurred within 20 days following surgery. Chronic obstructive pulmonary disease (odds ratio 1.909 [1.179–3.089]), renal failure (odds ratio 1.896 [1.172–3.066]) and the use of a bridge between different types of anticoagulant (odds ratio 2.793 [1.057–7.384]) were associated with TEV. The risk of bleeding was 5.67% at 1 month and 9.38% at 3 months (N=142). 77% of bleeding events were hematomas.

The risk of thromboembolic events is higher than expected in a population treated for this condition. Most thromboembolic events occur shortly following surgery. The risk of bleeding is high and most of them are hematomas. Future research could focus on the management of thromboprophylaxis in elderly patients undergoing surgery for a hip fracture.

Complex proximal humerus fractures account for 10% of fractures in patients over 65 years of age. With the emergence of new implants, there is growing trend towards surgical management of these types of fractures, despite the lack of clinical evidence of its superiority over a conservative option. Orthopaedic surgeons' perception plays a large role in the surgical decision making for complex proximal humerus fractures in the elderly. No studies have been conducted to date to examine factors that influence the surgical decision-making in orthopaedic surgeons in regards to these types of fractures.

A self-administered questionnaire was sent to orthopaedic surgeons. It included demographic questions as well as clinical vignettes assessing the risk / benefit perception of orthopaedic surgeons in different situations. Orthopaedic surgeons self-reported the proportion of proximal humerus fractures that were treated surgically in patients during the last year. Univariate analyzes were conducted to identify the factors that influenced the operation rates.

A total of 127 orthopaedic surgeons completed the questionnaire. The response rate was 37%. The risk / benefit perception of surgical management varied according to the type of practice, year of training, operation rate as well as the ease of the surgeon in performing shoulder procedures (p < 0.05). According to the queried surgeons, the most important factors affecting their decision-making were patient's age, the type of fracture, co-morbidities, level of independence and potential for rehabilitation. The type of surgery proposed varied depending on the training and familiarity of the surgeon with the procedure.

The risk / benefit perception of orthopaedic surgeons regarding surgical treatment of proximal humerus fractures in elderly patients appears to vary widely. The decision to opt for surgical management is influenced by the surgeon's familiarity with the procedure, their year of training and their subspecialty. This study demonstrates the need to establish a decision-making tool to assist orthopaedic surgeons and patients with this clinical decision.

Over the last decade, the number of total knee arthroplasty (TKA) has risen over 125%. Numerous studies have established a relationship between obesity and complications in primary TKA. Interestingly, few studies have investigated medical and orthopaedic complications in obese patients undergoing revision TKA (RTKA). With the increasing number of RTKA and with the prevalence of obesity still on the rise, the study of obesity on complications following RTKA is indicated.

We retrospectively reviewed 180 RTKA performed by a single surgeon done between August 2008 and June 2017. All patients who underwent RTKA were included, but revisions done with simultaneous extensor mechanism reconstruction and/or distal femur replacement were excluded since these procedures are technically more demanding. 154 revisions met our inclusion/exclusion criteriaes and were included in the final analysis. 81 patients were included in the non-obese group (BMI .

The total number of orthopaedic complications in the obese group (46.6%) was significantly higher than in the non-obese group (27.2%) (OR=1.71) (p = 0.01). The number of infection was higher in the obese group (11%) than in the non-obese (6.2%) but this was not statistically significant (OR=1.77) (p = 0.28). Reoperation rate was also higher in the obese group (23.3%) than in the non-obese group (16%) but this did not reach statistical significance (OR=1.46) (p = 0.26) (Table 3). Medical complications were higher in the obese group (31.5% vs 19.8%) (OR=1.59) (p=0.09). According to the Dindo-Clavien classification, the obese group demonstrated a significantly higher rate of grade 3 or higher complications (p = 0.01).

Obesity significantly increases the occurrence of orthopaedic complications following RTKA. Obesity also seems to increase the number of medical complications following RTKA. The obese patient should be informed prior to revision TKA that there is an increased risk of complications when compared with the non-obese patient. Further research with higher power would seem advisable to confirm this trend.

Surgeries for reverse total shoulder arthroplasty (RTSA) significantly increased in the last ten years. Initially developed to treat patients with cuff tear arthropathy (CTA) and pseudoparalysis, wider indications for RTSA were described, especially complex proximal humerus fractures.

We previously demonstrated in patients with CTA a different sequence of muscular activation than in normal shoulder, with a decrease in deltoid activation, a significant increase of upper trapezius activation and slight utility of the latissimus dorsi. There is no biomechanical study describing the muscular activity in patients with RTSA for fractures. The aim of this work is to describe the in vivo action of RTSA in patients with complex fractures of the proximal humerus.

We conducted an observational prospective cohort study comparing 9 patients with RTSA for complex humerus fracture (surgery more than 6 months, healed tuberosities and rehabilitation process achieved) and 10 controls with normal shoulder function. Assessment consisted in a synchronized analysis of range of motion (ROM) and muscular activity on electromyography (EMG) with the use of 7 bipolar cutaneous electrodes, 38 reflective markers and 8 motion-recording cameras. Electromyographic results were standardized and presented in muscular activity (RMS) adjusted with maximal isometric contractions according to the direction tested. Five basic movements were evaluated (flexion, abduction, neutral external rotation, external rotation in 90° of abduction and internal rotation in 90° of abduction). Student t-test were used for comparative descriptive analysis (p < 0,05).

The overall range of motion with RTSA is very good, but lower than the control group: flexion 155.6 ± 10 vs 172.2 ± 13.9, p<0.05, external rotation at 90° 55.6 ± 25 vs 85.6 ± 8.8, p<0,05, internal rotation at 90° 37.8 ± 15.6 vs 52.2 ± 12, p<0,05. The three heads of the deltoid are more stressed during flexion and abduction in the RTSA group (p

The increased use of the 3 deltoid chiefs does not support the hypothesis proposed by Grammont when the RTSA is performed for a complex proximal humerus fracture. This can be explained by the reduced dispalcement of the rotation center of the shoulder in these patients compared to those with CTA. These patients also didn't present shoulder stiffness before the fracture. The maximal muscle activity of the trapezius in flexion and of the latissimus dorsi in flexion and abduction had not been described to date. These new findings will help develop better targeted rehabilitation programs. In addition, the significant role of the latissimus dorsi must question the risks of its transfer (L'Episcopo procedure) to compensate for external rotation deficits.

Radial head fractures are common and mainly require a functional conservative treatment. About 20% of patients will present an unsatisfactory final functional result. There is, however, little data allowing us to predict which patients are at risk of bad evolve. This makes it difficult to optimize our therapeutic strategies in these patients. The aim of this study is to determine the personal and environmental factors that influence the functional prognosis of patients with a radial head fracture.

We realized over a 1-year period a prospective observational longitudinal cohort study including 125 consecutive patients referred for a fracture of the radial head in a tertiary trauma center. We originally collected the factors believed to be prognostic indicators: age, sex, socioeconomic status, factors related to trauma or fracture, alcohol, tobacco, detection of depression scale, and financial compensation. A clinical and radiological follow-up took place at 6 weeks, 3 months, 6 months, and 1 year. The main functional measurement tool is the Mayo Elbow Performance Score (MEPS) and the Disabilities of the Arm, Shoulder and Hand (DASH).

123 patients were included in the study. 114 patients required nonsurgical management. 102 patients completed the 1-year follow-up for the main outcome (89 for the DASH score). Two patients required an unplanned surgery and were excluded from analyses. At 1 year, the average MEPS was 96.5 (range, 65–100) and 81% of subjects had an excellent result (MEPS ≥90). The most constant factor to predict an unsatisfactory functional outcome (MEPS <90 or DASH >17) is the presence of depressive symptoms at the initial time of the study (P = 0.03 and P = 0.0009, respectively). This factor is present throughout the follow-up. Other observed factors include a higher socioeconomic status (P = 0.009), the presence of financial compensation (P = 0.027), and a high-velocity trauma (P = 0.04). The severity of the fracture, advanced age, female sex, and the nature of the treatment does not influence the result at 1 year. No factor has been associated with a reduction in range of motion.

Most of the radial head fractures heal successfully. We identified for the first time, with a valid tool, the presence of depressive symptoms at the time of the fracture as a significant factor for an unsatisfactory functional result. Early detection is simple and fast and would allow patients at risk to adopt complementary strategies to optimize the result.

Malnutrition is often associated with the advanced age and can be influenced by physical, mental, social and environmental changes. Hip fracture is a major issue and a prior poor nutritional status is associated with higher rates of perioperative complications and prolonged hospital length of stay.

Prospective observational cohort study performed in a Level one trauma center including 189 consecutive patients admitted for hip fracture. The main outcome measure was the Mini Nutritional Assessment (MNA), a specific tool validated for geriatric population. This questionnaire was performed at admission by an independent assessor, at the same time as a large set of demographic and functional data. Blood samples were tested for blood count and albuminemia. Two groups were constituted and analysed according to a MNA score ≥ 24 (lower limit for normal nutritional status). Factors explored included physical and mental items. Impact of malnutrition was determined on hospital length of stay (HLS), discharge in an adverse location than prior to admission (DAL), complications and mortality rate.

The rate of patients with malnutrition (or at risk) in this study is 47% (88 patients). Patients with a MNA < 24 are older (84.81 yrs ± 7.75 vs 80.41 ± 8.11, p<0,01), have more comorbidities (Charlson 2.8 ± 2.21 vs 1.67 ± 3.10, p<0,01), a more impaired mental (MMSE 19.39±8.55 vs 25.6±3.6, p<0,01) or physical status (MIF 105.3 ± 26.6 vs 121.8 ± 6.4, p< 0,01). Blood samples are not selective to detect malnutrition (p=0,64). Malnutrition is associated with a longer HLS (26.04±23.39 days vs 13.95±11.34 days, p<0,01), a greater DAL (58.9% vs 38.2%, p=0,02) and a higher one year mortality rate (23.9% vs 8.9 %, p<0,01).

The prevalence of malnutrition in a geriatric population admitted for hip fracture is high. Blood samples at admission have clearly a poor value and a systematic screening with the MNA is mandatory. An early diagnosis will target specific interventions to reduce the physical and socio-economic impact of the malnutrition. Future studies should focus on actions in the perioperative stage (fast-track surgery, nutritional protocols, analgesia) and their impact on the socio-economic burden.

Introduction

This paper describes the kinetic and electromyographic contribution of principal muscles around the shoulder of a cohort of patients with reverse total shoulder arthroplasty (RTSA). Surgeries for RTSA significantly increased in the last five years. Initially developed to treat patients with cuff tear arthropathy and pseudoparalysis, wider indications for RTSA were described (massive non repairable rotator cuff tears, complex 4-parts fractures). Since Grammont's theory in 1985, the precise biomechanics of the RTSA has not yet been demonstrated in vivo. Clinical results of patients with RSTA are still unpredictable and vary one from another.

Modularity in femoral revision stems was developed to reduce subsidence, leg length discrepancy and dislocation experienced in revision surgery. The Wagner SL Revision Stem (Zimmer, Warsaw, IN) has been known for excellent bony fixation and proximal bony regeneration, but the third-generation proportional neck offset and 135° neck-shaft angle has an unknown track record. Our aim is to study the effect of these design modifications on stem subsidence, dislocation rate and stem survival.

We reviewed 76 consecutive femoral revisions (70 patients; 50 M: 20 W; 67.7 yo [range; 37.7 – 86.6 yo]) with the Wagner SL implanted at our institution (2004–2012). No patient was lost to follow-up, but nine had died, and one patient was excluded for a Paprosky type I femoral bone defect. This leaves us 66 hips (60 patients) at 2 to 9.5 years of follow-up (mean 55 months; range, 24–114 months). Indications for revisions included aseptic stem loosening (62.1%), infection (13.6%), acetabular loosening (12.1%), recurrent dislocation (4.5%), periprosthetic (4.5%) and stem fracture (1.5%), and chondrolysis (1.5%). Patients were actively followed up at regular intervals to ascertain revision status and outcome measures including the Merle d'Aubigné (n=53), WOMAC questionnaires (n=59) and radiographs (n=66). Radiographs were evaluated for stem subsidence (mm).

One of the surviving 66 stems was revised for recurrent deep infection (1.5%). No patient underwent revision of the femoral stem for aseptic loosening or subsidence. The mean preoperative WOMAC scores (P: 12.8; S: 5.6; F: 51.8) had improved significantly at follow-up (P: 9.7;, S: 4.3; F: 37.6) (p<0.05). The mean Merle D'Aubigné score went from a pre-op of 8.2 (SD: 2.8; range 1 to 14) to a mean of 15.3 (SD: 2.6; range 7 to 18) (p<0,05) at the latest follow-up. During the follow-up period, 3 hips dislocated (4.5%). Each event happened prior to six months after surgery. Only one of these cases dislocated twice. Closed reduction was performed in all cases. None required revision surgery subsequently, and they all remained stable. The stem survivorship is 98.4% at 5 years (0.95 CI: 93–100) and 97.4% at 7.5 years (0.95 CI: 88.9–100). Stem subsidence of 0 to 5 mm was considered as not clinically significant (n=20; 30%). Stem subsidence of 5 to 10 mm occurred in 5 hips (7.6%)and stem subsidence greater than 10 mm only occurred in one hips (1.5%).

The third generation Wagner SL conical revision femoral stem has a lower rate of complication than its preceding generations, and is comparable to modular stems performance reported in current literature. These results motivate the authors to continue using monoblock conical revision femoral stems.

This paper presents the nutritional status of a geriatric population admitted for hip fracture. Malnutrition is often associated with the advanced age and can be influenced by physical, mental, social and environmental changes. Hip fracture is a major issue and a prior poor nutritional status is associated with higher rates of perioperative complications and prolonged hospital length of stay. Methods: Prospective observational.

Prospective observational cohort study performed in a Level one trauma centreincluding 110 consecutive patients admitted for hip fracture. The main outcome measure was the Mini Nutritional Assessment (MNA), a specific tool validated for geriatric population. This questionnaire was performed at admission by an independent assessor, at the same time as a large set of demographic and functional data. Blood samples were tested for blood count and albuminemia. Two groups were constituted and analysed according to a MNA score > 24 (lower limit for normal nutritional status). Factors explored included physical and mental items. Impact of malnutrition was determined on hospital length of stay (HLS), discharge in an adverse location than prior to admission (DAL), complications and mortality rate.

The rate of patients with malnutrition (or at risk) in this study is 49.1% (54 patients). Patients with a MNA < 24 are older (83.6 yrs ± 6.5 vs 80.2 ± 8.3, p<0,01), have more comorbidities (Charlson 2.5 vs 1.27, p<0,01), a more impaired mental (MMSE <27 74.1% vs 41.1%, p<0,01) or physical status (MIF 105.3 +/− 26.6 vs 121.8 +/− 6.4, p<0,01). Blood samples are not selective to detect malnutrition (p=0,64). Malnutrition is associated with a longer HLS (25.2 days +/− 24.2 vs 14.2 +/− 9.0, p<0,01), a greater DAL (58.9% vs 38.2%, p=0,02) and a higher 6 months mortality rate (16.7% vs 3.6%, p=0,02).

The prevalence of malnutrition in a geriatric population admitted for hip fracture is high. Blood samples at admission have clearly a poor value and a systematic screening with the MNA is mandatory. An early diagnosis will target specific interventions in order to reduce the physical and socio-economic impact of the malnutrition. Future studies should focus on actions in the perioperative stage (fast-track surgery, nutritional protocols, analgesia) and their impact on the socio-economic burden.

There is no clear consensus regarding the indications for surgical treatment of middle third clavicle fractures. An initial shortening of 2 cm or more of the clavicle was associated with poor clinical outcomes and higher rate of non-union. The number needed to treat (NNT) clavicle fractures in order to prevent non-union ranges in the recent literature from 4.5 to 9.2. A direct relationship between shortening of the clavicle and a poor clinical outcome has not yet been demonstrated.

Prospective cohort study performed in a Level one trauma centre including 148 clavicle fractures treated conservatively. Eighty-five patients met the inclusion criteria (healed fracture in the middle third, no other upper limb lesions) and 63 were enrolled. A single assessment was realised at a minimum one year follow-up by an independent examiner and consisted in Constant and DASH scores, range of motion, strength in abduction (Isobex) and a specific radiographic evaluation using a calibrated AP radiographs of both clavicles. Two groups were constituted and analysed according to a radiologic shortening > 2 cm (patients and assessor blinded). Sub-analyses were performed to find any relevant clinical threshold.

The rate of shortening > 2cm in this cohort is 16.1% (10 patients). No clinical differences between the two groups for Constant scores (shortened > 2 cm = 96.0 ± 6.0 vs 95.2 ± 6.6, p=0,73) and DASH scores (8.4 ± 11.9 vs 5.4 ± 8.1, p=0,32). A slight loss in flexion was observed with a shortening > 2cm (175 deg ± 8.5 vs 179.3 ± 3.4, p=0,007). No clinical threshold (in absolute or relative length) was associated with lower functional scores. No relationship between clinical results and patient characteristics. Interestingly, cosmesis was not an issue for patients.

This study could not demonstrate any clinical impact of the shortening of the clavicle in patients treated conservatively for a fracture in the middle third. Functional scores are excellent and the slight difference in flexion is not clinically significant. We were not able to found patients unsatisfied with their treatment. The poor functional outcomes described in previous studies are mainly related to non-unions. Just after the trauma, protraction of the scapula and single AP views centered on the clavicle can overestimate the real shortening. An initial shortening of the clavicle > 2 cm is not a surgical indication for fractures in the middle third; patient selection for surgery should focus on risk factors for non-unions.

The traditional treatment for a primary anterior shoulder dislocation has been immobilisation in a sling with the arm in adduction and internal rotation. The recurrence rates after the initial traumatic event range from 20% to 94%. However, recent results have suggested that recurrent instability after primary shoulder dislocation may be reduced with immobilisation in external rotation. Since then, controversy exists regarding the position of immobilisation following these injuries. The objective of the present study was to compare immobilisation in internal and external rotation after a primary anterior shoulder dislocation.

Fifty patients presenting to our fracture clinic with a primary traumatic anterior dislocation of the shoulder were randomly assigned to treatment with immobilisation in either internal rotation (IR; 25 patients) or external rotation (ER; 25 patients) for three weeks. In addition of a two-years clinical follow-up, patients underwent a magnetic resonance imaging (MRI) of the shoulder with intra-articular contrast within four days following the traumatic event, and then at three months of follow-up. The primary outcome was a recurrent dislocation within 24 months of follow-up. The secondary outcome was the healing rate of the labral lesion seen on MRI (if present) within each immobilisation group.

The follow-up rate after two years was 92% (23 of 25) in the IR group and 96% (24 of 25) in the ER group. The recurrence rate in the IR group (11 of 23; 47.8%) was higher than that in the ER group (7 of 24; 29.2%) but the difference did not reach statistical significance (p=0.188). However, in the subgroup of patients aged 20–40 years, the recurrence rate was significantly lower in the ER group (3 of 17; 6.4%) than that in the IR group (9 of 18; 50%, p<0,01). In the subgroup of patients with a labral lesion present on the initial MRI, the healing rate of the lesion was 46.2% (6 of 13) in the IR group and 60% (6 of 10) in the ER group (p=0.680). Overall, the recurrence rate among those who showed healing of the labrum (regardless of the immobilisation group) was 8.3% (1 of 12), but patients who did not healed their labrum had a recurrence rate of 45.5% (5 of 11; p=0.069).

This study suggests that immobilisation in ER reduces the risk of recurrence after a primary anterior shoulder dislocation in patients aged between 20 and 40 years. At two years follow-up, the recurrence rate is lower in patients who demonstrated a healed labrum at three months, regardless of the position of immobilisation. Future studies are required in order to identify factors that can improve healing of the damaged labrum following a traumatic dislocation of the shoulder.

Background:

Total knee replacement (TKR) is a frequent and effective surgery for knee osteoarthritis. Postoperative pain is under concern and can be relieved by different methods, including femoral nerve block (FNB). The efficacy of FNB on pain relief was associated with the absence of clinical impact when measured with the range of motion (ROM). Recent studies suggest that the quadriceps strength is the best indicator of functional recovery after TKR. The goal of this study is to compare the quadriceps strength recovery after TKR according to the kind of analgesia (patient control analgesia (PCA) with or without FNB) Hypothesis: the FNB delays the QSR at short and mid-term follow-up.

Purpose

Tape blisters after hip surgery are frequent. There are source of pain, an obstacle for rapid rehabilitation and an open door for infection. Previous studies have shown a reduction up to 10% according to the type of bandage. A previous survey in our hospital demonstrated more than 50% of patients presenting tape blisters with the use of Hypafix. The purpose of this prospective study was to compare the prevalence of blisters with the use of three different kinds of bandages.

Objective: The main treatment for unstable distal radius fracture in Québec consists in pinning and cast, with secondary shortening and displacement responsible for lack of motion. The goal of the study is to compare clinical and radiological results after treatment with non-bridging external fixator compared to pinning and cast, with restoration of grip strength as main clinical outcome.

Method: Between June 2003 and June 2005, 120 consecutive patients admitted for unstable extra-articular distal radius fracture were randomized in the 2 groups. Early mobilisation was allowed in the group with external fixator, and patients in the other group had pins and cast for 6 weeks. Follow-up was completed after 6 months with determination of clinical and radiological data for the both wrists.

110 patients completed the study, with 2 comparative groups for epidemiologic and radiological criteria (n = 63 for pins and 57 for external fixator).

Results: Grip strength was significantly better in the fixator group at 3 months (68,36%;p< 0,001) and 6 months (98,26%;p< 0,001). Active ROM was better and obtained earlier in the fixator group in all directions (p< 0,001). Fixator prevent shortening and secondary displacement in a highly significant way (p< 0,001). No difference in pain medication, but fixator group could begin occupation earlier (p< 0,001).

Conclusion: Non-bridging external fixator is a treatment of choice for unstable extra-articular distal radius fractures. The immediate stability allows in all patients (without influence of age, bone quality or fracture displacement) early mobilisation, prevent secondary displacement, and gives earlier and better functional results.
