Introduction

The current treatment for Freiberg's osteochondrosis centres around either: simple debridement or debridement osteotomy. The main principle of the osteotomy is to rotate normal articular cartilage into the affected area. We recommend the use of CT scanning to delineate the amount of available, unaffected cartilage available to rotate into the affected space.

Aims

To determine the impact of COVID-19 on orthopaediatric admissions and fracture clinics within a regional integrated care system (ICS).

The accessory navicular (AN) is a separate ossification center for the tuberosity of the navicular that is present in approximately 5–14% of the general population. It produces a firm prominence on the plantar-medial aspect of the midfoot. There may be a co-existent flexible flatfoot, but there is no conclusive evidence of a cause-and-effect relationship between the two conditions. It is usually not symptomatic, and few cases necessitate operative intervention. When symptoms require surgical treatment, excision of the AN, with or without advancement of the posterior tibial tendon, usually is considered.

To describe new technique of AN excision and tibialis posterior tendon advancement (TPTA) using a bio-absorbable tenodesis screw and to investigate the outcome of this cohort in comparison to conventional simple excision.

Retrospective 2 Cohort study. Single surgeon series from single institution. All patients younger than 18 years from Jan 2000 to Aug 2012 undergoing simple excision (SE) or excision with TPTA were identified from the prospectively collected database. Case notes were reviewed and data regarding demographics, indications for surgery, presence of Pes Planus, time from presentation to surgery, length of follow-up, patient satisfaction and complications were recorded. Pain and functional outcome were measured using Visual Analogue Score (VAS) and patient reported outcome measure- Oxford Ankle Foot Questionnaire- Child and Teenager Version.

There were 6 patients in SE group. There were 3 males and 3 females. Mean age at surgery was 13.9 years. Surgical indication was painful swelling in all patients and in addition 1 had pes planus. There were 7 in SE & TPTA group. There were 3 males and 4 females. The mean age at surgery was 13.1 years. Surgical indication was painful swelling in all patients and in addition 1 had hind foot rigidity and 3 had pes planus. Postoperative protocol involved weight bearing with or without cast in SE group and non-weight bearing in cast for 6 weeks in TPA group. All patients reported excellent to good outcome. There were no complications and no reoperations after tendon advancement.

In conclusion, based on our study findings, we think AN excision and TP advancement is a safe and effective technique for symptomatic pain relief. It is a novel technique which achieved excellent to good outcome in our series.

Aim

Differing reports about the surgical management of the supracondylar humeral fracture make evidence-based practice very difficult, so knowledge of the contemporary practices and opinions of an expert body can provide a useful benchmark for appraisal; the aim of this study was to obtain this information.

Background

Lateral column lengthening combining bony and soft tissue procedures has been described for symptom relief and deformity correction in the planovalgus foot. There are relatively few reports on its outcomes in childhood. We present our medium term outcomes using this technique in children.

Aim

To investigate the effectiveness of a decision-based protocol designed to minimise the use of medial incisions when performing crossed-wire fixation of supracondylar fractures of the distal humerus whilst minimising ulnar nerve injury.

Introduction

Medial calcaneal displacement osteotomy with an FDL tendon transfer is a common method of correcting pes planus deformity secondary to grade II tibialis posterior dysfunction. There is currently no evidence that calcaneal displacement alters the centre of pressure in the foot from a medial to a more central position as the normal shape is reconstituted.

Aims

The purpose of this study was to calculate the dislocation rate following open or closed reduction for developmental dysplasia of the hip (DDH) in our unit. In addition we evaluated the posterior neck line as a method of determining hip relocation and assessed the morphology of the dysplastic acetabulum on single slice CT scan.

Background: A novel method for harvesting the flexor digitorum longus (FDL) tendon has previously been described via a plantar approach based on a surface coordinate. The aim of this investigation is to provide a comparison with the traditional medial midfoot dissection for tendon harvest.

Methods: The FDL tendon was exposed in 10 cadaveric feet via a limited plantar approach and also medially as far as could be accessed via the knot of Henry. The FDL was marked with a metal clip in each approach. The lengths of the skin incisions were recorded and the distance between the two markers was measured. The morphology of the FDL tendon was observed including interconnections with the flexor hallucis longus (FHL) tendon.

Results: The mean additional length of tendon accessed via the plantar approach was 22.9 mm with a mean reduction in skin incision length of 15.6 mm. The FDL tendon showed some division at the site of the plantar exposure and there were FDL - FHL interconnections in nine of the feet with three distinct patterns observed.

Conclusion: Using the plantar exposure, a longer length of tendon can be obtained through a smaller skin incision, which has been quantified here. Observations on FDL tendon morphology and interconnections may have clinical significance.

Introduction: The assessment of quality in the provision of healthcare is one of the core features of the National Health Service in the 21st Century. From April 2009 Patient Reported Outcome Measure (PROM) data are being collected for the Department of Health for elective hip and knee arthroplasty using generic and disease specific measures of health status. The perceived uses of these data may be for research, assessment of procedural outcome, measures of health inequalities and to aid commissioning groups in selecting their secondary care providers. Foot and ankle surgery covers a wide spectrum of operative procedures with patient responses less predictable than with major joint arthroplasty. We report the use of a sixteen point satisfaction-based questionnaire in order to investigate the nature of patient outcome after the processes of foot and ankle surgery.

Methods: A prospective series of 100 two-part Visual Analogue Scale (VAS) questionnaires was distributed to patients undergoing elective foot and ankle surgery at the Northern General Hospital under the care of four foot and ankle surgeons over a three-month period. The questionnaires were numbered to allow patient anonymity. The first part of nine questions enquired about pre-operative preparation and information and was distributed before surgery. The second part of seven questions, distributed at the first post-operative clinic sought to investigate their hospital and operative experience. Free text comments were requested in addition to the VAS responses, which were expressed as percentages.

Results: 97% of part one and 85% of part two questionnaires were returned completed. 82% had both parts completed and matched. The day case to inpatient ratio was 55: 45. For part one, all clinically related questions scored more than 90% satisfaction, with only two scores for administration-based questions falling below this level. For part two, satisfaction for clinical questions again scored more than 90% and overall, all scored more than 80% satisfaction. Only 23% of pre-operative and 28% of post-operative questionnaires were returned with free-text comments.

Conclusions: A simple patient satisfaction-based questionnaire may be as useful as existing non-validated generic scoring systems used in foot and ankle surgery when assessing quality in the health service, particularly where regional demographics or referral patterns may be important factors influencing patient outcomes. Active dialogue with the surgical colleges and Department of Health should be pursued to avoid inappropriate outcome measures being imposed in foot and ankle surgery.

In 2000 our emergency department implemented a new management for the treatment of isolated, apex volar distal radial fractures involving immobilisation with a wrist splint, written information for carers and no planned follow up. Next day x-ray review acted as a safety net for misdiagnosed or less stable fractures.

This has now been validated with a retrospective review of treatment for distal radial # within the ED.

Patients were identified through the Emergency department’s electronic discharge record. Over a 9 month period 260 patients were identified with metaphyseal distal radial and/or ulna injuries to which a non orthopaedic junior doctor might be expected to apply the Buckle Fracture Algorithm. Of these 161 had isolated distal radial fractures suitable for treatment with a wrist splint. 118 were correctly identified and treated in the ED. 43 patients were sent to # clinic, of these 11 patients were discharged at the 1st visit, however 3 had 3 or more visits and 2 children had additional x-rays. Over this period 9 children were given splints inappropriately according to the protocol, most of these had stable injuries on reviewing the x-rays, 3 were identified and recalled for a cast. None of the children with injuries outside the protocol who were not recalled had an unplanned return with complications.

Taking into account only those children who were correctly managed from the ED the estimated annual cost savings to the NHS for this hospital for this period is £40,784, compared to standard treatment before introduction of this protocol. If all children had been treated according to protocol the estimated cost savings would be £56096/yr.

Aim: To review our experience with hemi-epiphysiodesis using different methods for the correction of angular deformity about the knee.

Method: This was a retrospective review of 73 patients (101 knees) who underwent hemi-epiphysiodesis from 1999 to 2008. Assessment looked at the type and degree of deformity, implants used, average operating time and hospital stay, complications, degree of correction and the average time to correction.

Results: There were 50 boys and 23 girls with bilateral deformity in 28 cases. There were 88 valgus and 13 varus knees. Average follow-up was 17 months. Staples were used in 28 cases, “8” Plates in 24, Screws in 16 and Drilling in 5 cases. The distal femoral physis was involved in 46 knees, the proximal tibial physis in 21 and both physes in 34 knees (total 135 physes). Average operation time and hospital stay were similar for all methods. There were 6 minor and 3 major complications with staples with an average correction time of 14 months, 3 minor complications with an average correction time of 11 months with “8” plates, 3 minor and 1 major complication with an average correction time of 14 months with screws and 1 minor complication with drilling with an average correction time of 13 months. The outcome was considered as resolved in 47 and pending in 26 cases, with all showing progressive correction of deformity.

Conclusions: Hemi-epiphysiodesis by any method is an effective way to correct angular deformities about the knee in skeletally immature individuals within a reasonable time limit and with minimal morbidity when compared to a corrective osteotomy. Our experience suggests that “8” plates achieve faster correction with the least complications when compared to other methods. Valgus knee deformities corrected faster than varus ones.

Introduction: This study examined the cohort of patients selectively screened over a 5 year period with ultrasonography according to our risk factors (positive Ortolani or Barlow manoeuvre, breech presentation, first degree affected relative and talipes equinovarus) for developmental hip dysplasia (DDH). The aims were to evaluate the success of those managed in a Pavlik harness and identify predictive factors for those that failed treatment.

Methods: 1181 patients were selectively screened between 1999 and 2004. Of those, 128 patients (189 hips) were identified as having hip instability. Failure was defined as inability to achieve or maintain hip reduction in a Pavlik harness. A proforma was designed to document patients’ risk factors and ultrasound findings at time of initial dynamic ultrasound scan where the senior radiographer and treating consultant were present. Each hip was classified according to Graf type. Acetabular indices were recorded prior to discharge.

Results: All 128 patients with hip instability were managed in a Pavlik harness. This was abandoned for surgical treatment in 9 patients (10 hips) giving a failure rate of 5.3 % (0.17 per 1000 live births). All those successfully managed had an acetabular index of less than 30 degrees at follow up (6 – 48 months). 7 hips in the series were classified as Graf type IV, of these, 6 went on to fail management in a Pavlik harness. 67% of those that failed were also breech presentation compared to 22% of those managed successfully. There were no complications associated with management in a Pavlik harness. 16 patients born within our region presented after 12 weeks of age with DDH resulting in a late presentation rate of 0.3 per 1000 live births.

Discussion: Our overall rate of selective screening is 14 per 1000 live births with a subsequent treatment rate of 2.3 per 1000 is comparable with other centres. Our rate of failure for DDH in a Pavlik harness 0.17 per 1000 live births is an improvement on any previously published results. Irreducible hips, Graf type IV hips and breech presentation correlated with a high likelihood of treatment failure.

Introduction: Ankle fractures accounts for 25% to 38% of all physeal fractures. An accurate diagnosis is the key to the appropriate management of these fractures. Traditionally the management decisions have been based on x-ray findings. We have used computed tomograpy (CT) scans in additon to x-rays in the management of these fractures.

Objective: To determine the usefulness of computed tomograpy (CT) scans in the management of ankle fractures in children.

Materials and Methods: Between 2001 to 2005, 53 patients with ankle fractures who were managed in our unit had CT scans in addition to plain radiographs. The mean age was 12.3 years (+/− 2.1). The radiographs were reviewed by senior paediatric orthopaedic surgeon who classified the fractures and formulated treatment plans (operative/non-operative). The CT scans were then reviewed by the respective surgeon and a similar exercise undertaken. A Radiologist confirmed that the fractures were classified accurately.

Results: In 47% (25 fractures) the x-ray diagnosis/classification tallied with the CT scans whilst in 53% (28 fractures) the CT scans showed the fractures were more extensive/serious than noticed on the x-rays. The management was changed in 34% after reviewing the CT scans, In 9 from operative to non-operative treatment and in the other 9 from non-operative to operative treatment.

Conclusion: We have found CT scans to be more useful than plain radiographs in making an accurate diagnosis of ankle fractures in children and thus planning appropriate management.

Aim: To report our experience and early results with flexible nailing for unstable or irreducible displaced proximal humeral fractures in children.

Material & methods: Between 1997 & 2004, 15 children with unstable or irreducible displaced fractures of the proximal humerus were treated with closed/open reduction and flexible IM nailing. There were 10 boys and 5 girls. The median age of the patients was 12.5 years (9–15). Thirteen children had a Salter – Harris II, Neer grade III/IV fracture and 2 children had metaphyseal fractures. The outcome assessment was performed using the shoulder score, clinical and radiological parameters.

Results: All fractures united. None of the patients had a clinically significant malunion/shortening. Three patients had irritation at the nail insertion site. One patient had a transient radial nerve neurapraxia. There were no other operative or postoperative complications. The flexible nails were removed at a median time of 6 months (1.5–10) in 12 patients and 3 patients are awaiting removal. At a median follow-up of 30 months (4–66) all patients had a normal or near normal glenohumeral motion, full strength and all reported regaining full pre-injury functional use of the involved extremity.

Conclusion: Flexible nailing can be used safely to maintain reduction in unstable or irreducible displaced fractures of the proximal humerus and allows early return to normal activities and function with minimal complications. This treatment is also useful in older children who have minimal remodelling potential.

Background The ossific nucleus of the femoral head is usually present ultrasonographically around 12 weeks of age. It has been considered that the presence of an ossific nucleus in the femoral head is an indication of hip stability. In the ultrasound scan clinic for the assessment of developmental dysplasia of the hip at Sheffield Children’s Hospital, we have identified unstable hips with ossific nuclei, as well as, the appearance of ossific nuclei at as early as 2 weeks of age. These observations suggested the need to clarify the initial considerations that the ossific nucleus appeared ultrasonographically around 12 weeks of age and was an indicator of hip stability.

Aim To determine the relationship, if any, between the presence of the ossific nucleus of the femoral head ultrasonographically and stability of the hip.

Patient selection We have included in our study all the children who have had an ultrasound scan of their hips from 1996 to 1999 at Sheffield Children’s Hospital for suspected developmental dysplasia.

Methodology We have retrospectively reviewed reports of ultrasound scans performed for developmental dysplasia of the hip between 1996 and 1999. We have looked at the report for both the hips of each child. We have collected and analyzed data with regard to the age of the child at the time of the scan, the depth of the acetabulum, the shape of the femoral head, the presence or absence of an ossific nucleus, the dynamic stability of the hips and the congruity of the joint as reported on the ultrasound report. We report the findings in the first 318 hips of the 627 available patients in the study period.

Results The ossific nucleus can appear as early as 2 weeks and yet may not be visible until 24 weeks. In the 318 hips examined the ossific nucleus was present in 46 (14.47%). The age range for these scans was 1–40 weeks after birth. Of the 318 hips 252 (79.24%) were stable on dynamic screening, 274 (86.16%) had a normal(spherical) appearance of the femoral head, 209 (65.72%) had normal acetabular development and 263 (82.7%) demonstrated congruence of the hip joint. These data have been analyzed using Microsoft excel at confidence intervals of 0.8, which suggest no relationship between the presence of the ossific nucleus and hip stability.

Conclusion The limited early results of this study have shown that the ossific nucleus of the femoral head can appear from a very early age, may not appear until well after 12 weeks of age and is not an indicator of hip stability. Its presence on ultrasound scan does not exclude developmental dysplasia of the hip.

Aim: The purpose of this prospective study was to assess the outcome of scarfe osteotomy for hallux valgus. Method: 26 patients were reviewed but only the results of 24 patients (33 osteotomies) were available for analysis. The assessment involved the American Academy Foot and Ankle Society Score, pedobarographic & radiographic examination.

There were 3 male and 21 female patients with a mean age of 46 years. The mean follow up was 17 months. Statistical analysis was carried out. Results: The AAFAS score improved from a mean preoperative value of 52 to 89 postoperatively. The mean improvement was 34 (range 12–46). The inter-metatarsal and hallux valgus angles improved from a mean preoperative value of 15 and 31 degrees respectively to a mean postoperative value of 8 and 14 degrees. 22 patients (91.6%) were satisþed with the outcome of surgery. The pedobarographic results will be illustrated. In one patient a fracture occurred intra-operatively and two patients had wound infection which settled with antibiotics. Conclusion: The early results of the scarfe osteotomy for hallux valgus in our hands are encouraging.

Aims: To test the hypothesis that there is a trend to over correction in patients who demonstrate signs of generalised joint laxity.

Patients and methods: 41 patients with an average age of 6.5yrs (3–15) were examined for generalised joint laxity using the Biro score. This gave 52 feet (11 bilateral) for clinical assessment using the podoscope and graded based on Tachdijans flat foot score.

Results: The results were assessed and the patients divided into 2 groups depending on whether or not they had joint laxity. This left 15 patients with 18 feet in the non-lax group and 26 patients with 34 feet in the lax group. The 2 groups were then compared to see if there was a difference in flat foot grade. In the non-lax group 2 patients showed evidence of over-correction whereas in the lax group 25 patients were over corrected to some extent. Using the fisher’s exact test there was a significant difference between the 2 groups with a trend towards over correction in those with generalised joint laxity (p = 0.002).

Conclusion: Based on the findings of this study there is a correlation between generalised joint laxity and over correction in congenital talipes equino-varus.

Aims: To test the hypothesis that there is a trend to over correction in talipes patients who demonstrate signs of generalised joint laxity.

Patients and Methods: 45 patients with an average age of 6.9yrs(3–16) were examined for generalised joint laxity using the Biro score. This gave 65 feet (20 bilateral) for clinical assessment using the podoscope and graded based on Tachdijans flat foot score.

Results: The results were assessed and the patients divided into 2 groups depending on whether or not they had joint laxity. This left 19 patients with 26 feet in the non-lax group and 26 patients with 39 feet in the lax group. The 2 groups were then compared to see if there was a difference in flat foot grade. In the non-lax group 2 patients showed evidence of over-correction whereas in the lax group 18 patients(25 feet)were over corrected to some extent. Using the fisher’s exact test there was a significant difference between the 2 groups with a trend towards over correction in those with generalised joint laxity (p=. 002).

Conclusion: Based on the findings of this study there is a correlation between generalised joint laxity and over correction in congenital talipes equinovarus.

To assess patient/parent satisfaction with treatment of radial Forearm Buckle Fractures without the necessity of fracture clinic visits.

A+E staff were provided with definitions and suitable example X-Rays of radial forearm buckle fractures. The A+E staff were asked to mark the films with a green dot for Radiological review if the patient was included in the study, and these films were seen within 24 hours by a consultant radiologist.

Over a three month period all patients with radial forearm buckle fractures seen in A+E were treated with an Alder Hey splint rather than plaster, they were then given a fracture clinic appointment for three weeks later. At this visit the medical staff completed a proforma with the following information, appropriateness of the diagnosis, side, bone/cortex involved, degree of angulation as well as the mode of injury.

The patients and their parents were asked whether they were happy with the level of support that the splint gave and whether they would have been happy to remove the splint without visiting the fracture clinic.

72 (86.7%) had suffered low energy injuries, 5 (6%) high energy injuries, 5 (6%) did not attend their clinic appointment.

65 of 78 (83%) of parents and 65 of 72 (90%) of patients felt that the level of provided support was adequate (6 patients too young to answer)

58 of 78 (74%) of parents and 53 of 72 (74%) of patients would have been happy to make the decision to remove the splint themselves (6 patients too young to answer)

5 (6%) of the diagnoses were deemed to be inappropriate, of these 2 were picked up in radiology review and sent to clinic and 3 were soft tissue injuries.

We feel that the results show that the majority of patients with radial forearm buckle fractures (appropriate guidelines available to A+E staff) do not need to be seen in the fracture clinic, as long as their X-Rays are reviewed and any inappropriately diagnosed fractures sent to clinic. This has significant implications both for fracture clinic workload and also financially for hospitals.
