Introduction:. Unstable ankle fractures are commonly treated with operative fixation. Isolated lateral malleolus fractures (Weber B) are often operated by orthopaedic trainees. Operative fixation of these fractures is included in the index procedures of procedure based assessment (PBA) of intercollegiate Surgical Curriculum Programme (ISCP). Orthopaedic trainees are expected to be competent in this procedure by the end of their training. Fluoroscopic guidance is essential for adequate reduction and safe fixation of these fractures. Aims:. It is currently unknown if patients are exposed to excess radiation when they are operated by trainees compared to consultant surgeons. It is a common perception that trainees take more time to fix these fractures compared to trained consultants thereby exposing patients to untoward effects of prolonged tourniquet time. Method:. A retrospective review of fifty patients undergoing operative fixation of Weber B lateral malleolus fractures were undertaken. Twenty five patients were operated by orthopaedic consultants and the remaining (n=25) by orthopaedic trainees. The tourniquet time and the intra-operative radiation dose using the fluoroscope were recorded. Results:. Patients operated by trainees were exposed to significantly higher dose of intra-operative radiation (median, 6.5 Gy vs 46.2 Gy; interquartile range, 0.87–15.8 vs 8.37–140.3; P=0.003). However, there was no statistical difference in the duration of application of the tourniquet in between the two groups (median, 59 minutes vs 79 minutes; interquartile range, 45–95 vs 69–102; P=0.12). Discussion:. This is the first study to indicate that patients are at risk of higher radiation exposure when operated by orthopaedic trainees whilst the times taken to fix Weber B ankle fractures are almost similar to those undergoing surgery by a consultant grade surgeon

Aims

Despite the increasing numbers of ankle arthroplasties, there are limited studies on their survival and comparisons between different implants. The primary aim of this study was to determine the failure rates of primary ankle arthroplasties commonly used in the UK.

Hammer toe involves metatarsophalangeal joint (MTPJ) hyperextension and proximal interphalangeal joint (PIPJ) flexion. Surgery commonly involves excision arthroplasty or fusion of the PIPJ with MTPJ soft tissue release if necessary. Previous series record that MTPJ release was carried out “as required” but not how often release is necessary. Myerson and Shereff's (1989) cadaver study found release of the extensors, MTPJ capsule and collateral ligaments necessary for full hammertoe correction. Hossain (2002) found the clinical results of this procedure were no better than simple PIPJ fusion. We release the MTPJ if hyperextension persists after PIPJ correction and release the components sequentially. We studied how often and how extensive a release was required, and how this corelated with pre-operative assessment. We reviewed the records of 164 patients who had hammer toe correction under one consultant surgeon. Patients with complex corrections were excluded. The severity of the pre-operative deformity was classified as type 1 (PIPJ and MTPJ correctable), 2 (PIPJ fixed, MTPJ correctable) or 3 (neither joint correctable). We recorded the extent of release required for each toe. Results. Of 334 type 2 toes in 146 patients, 178 (53.3%) required no MTPJ release, 11 (3.3%) extensor tenotomy only, 15 (4.5%) extensor tenotomy and MTPJ dorsal capsulotomy and 130 (38.9%) extensor tenotomy, capsulotomy and collateral ligament release. Of 31 type 3 toes in 18 patients, one (3.2%) needed no release, 2 (6.5%) tenotomy, one (3.2%) capsulotomy and 27 (87.1%) complete release. Discussion. Nearly 50% of toes needed MTP soft tissue release, partial in 8%. Pre-operative assessment was not very accurate in predicting the need for release. We have not yet correlated need for release with clinical outcome. Conclusion. MTP release is required in many hammertoe corrections. Assessment of toe position after incision of each structure may avoid the need for complete release

Introduction. We aimed to retrospectively identify risk factors for delayed / non-union for first metatarsophalangeal joint fusion. Methods. Case notes and radiograph analysis was performed for operations between April 2014 and April 2016 with at least 3 months post-operative follow up. Union was defined as bridging bone across the fusion site on AP and lateral radiographic views with no movement or pain at the MTPJ on examination. If union was not certain, CT scans were performed. All patients operations were performed/supervised by one of three consultant foot surgeons. Surgery was performed through a dorsal approach using the Anchorage compression plate. Blinded pre-operative AP radiographs were analysed for the presence of a severe hallux valgus angle equal or above 40 degrees. Measurement intra-observer reliability was acceptable (95%CI:1.6–2.3 degrees). Smoking and medical conditions associated with non-union underwent univariate analysis for significance. Results. 73 patients, 9 male, 64 female with a mean age of 61 years (range, 29 to 81) comprised the patient group. Mean follow up time was 13 months for both union vs non-union groups (range 3 to 24 months). 7 patients were identified as non / delayed union (9.6%). All smokers healed (n = 17), age, diabetes, COPD and rheumatoid arthritis did not show significant associations with non-union. Pre-operative hypothyroidism (relative risk 6.9, p = 0.05) and severe hallux valgus (relative risk 9.9, p = 0.002) were significantly associated with non / delayed union. Conclusion. Although overall bone mineral density is unaffected, studies have demonstrated abnormal bone remodelling in patients with hypothyroidism which may account for this unexpected finding. A dorsally placed locking plate with a dorsal to plantar placed compression screw is at a biomechanical disadvantage to resist lateral force when trying to hold a corrected severe hallux valgus. These patient groups may benefit from supplementary fixation techniques

Aims

This is the first prospective study to report the pre- and post-operative patient reported outcomes and satisfaction scores following excision of interdigital Morton’s neuroma.

Most of the literature on surgical site infections following the surgical treatment of fractures of the ankle is based on small series of patients, focusing on diabetics or the elderly. None have described post-operative functional scores in those patients who develop an infection. We performed an age- and gender-matched case–control study to identify patient- and surgery-related risk factors for surgical site infection following open reduction and internal fixation of a fracture of the ankle. Logistic regression analysis was used to identify significant risk factors for infection and to calculate odds ratios (OR). Function was assessed using the Olerud and Molander Ankle Score. The incidence of infection was 4% (29/717) and 1.1% (8/717) were deep infections. The median ankle score was significantly lower in the infection group compared with the control group (60 vs 90, Mann–Whitney test p < 0.0001). Multivariate regression analysis showed that diabetes (OR = 15, p = 0.031), nursing home residence (OR = 12, p = 0.018) and Weber C fractures (OR = 4, p = 0.048) were significant risk factors for infection.

A low incidence of infection following open reduction and internal fixation of fractures of the ankle was observed. Both superficial and deep infections result in lower functional scores.

A total of 80 patients with an acute rupture of tendo Achillis were randomised to operative repair using an open technique (39 patients) or non-operative treatment in a cast (41 patients). Patients were followed up for one year. Outcome measures included clinical complications, range of movement of the ankle, the Short Musculoskeletal Function Assessment (SMFA), and muscle function dynamometry evaluating dorsiflexion and plantar flexion of the ankle. The primary outcome measure was muscle dynamometry.

Re-rupture occurred in two of 37 patients (5%) in the operative group and four of 39 (10%) in the non-operative group, which was not statistically significant (p = 0.68). There was a slightly greater range of plantar flexion and dorsiflexion of the ankle in the operative group at three months which was not statistically significant, but at four and six months the range of dorsiflexion was better in the non-operative group, although this did not reach statistically significance either. After 12 weeks the peak torque difference of plantar flexion compared with the normal side was less in the operative than the non-operative group (47% vs 61%, respectively, p < 0.005). The difference declined to 26% and 30% at 26 weeks and 20% and 25% at 52 weeks, respectively. The difference in dorsiflexion peak torque from the normal side was less than 10% by 26 weeks in both groups, with no significant differences. The mean SMFA scores were significantly better in the operative group than the non-operative group at three months (15 vs 20, respectively, p < 0.03). No significant differences were observed after this, and at one year the scores were similar in both groups.

We were unable to show a convincing functional benefit from surgery for patients with an acute rupture of the tendo Achillis compared with conservative treatment in plaster.
