We have recently described an extended lateral approach to the hindfoot for the operative treatment of displaced intra-articular fractures of the calcaneum. It has the advantage of avoiding damage to the sural nerve and preserving blood supply to allow prompt healing. We dissected 15 formalin-preserved cadavers, taking photographs to show the structures of the posterolateral aspect of the hindfoot and ankle. We describe a superficial and a deep triangle: the deep triangle contains a constant posterior peroneal artery which supplies the skin of the posterolateral heel. An approach designed to expose the sural nerve will divide this important artery and cause ischaemia of the posterior skin. The extended lateral approach elevates the sural nerve in a thick flap and preserves the blood supply of the skin. We have reviewed 150 consecutive patients after the use of this approach to study the indications for operation, the quality of wound healing, any damage to the sural nerve and other complications. We recommend the careful use of this approach. Our understanding of its anatomical basis has allowed us to widen the indications for its use

Background. Traditionally, the extended lateral approach (ELA) was the favoured approch for calcaneal fractures, but has been reported to have high incidence of wound complications. There has been a move amongst surgeons in the United Kingdom towards the sinus tarsi approach (STA) due to its minimally invasive nature, attempting to reduce such complications. Aims. To evaluate outcomes of ELA and STA for all consecutive calcaneal fracture fixation in our institution over a 10yr period. Method. Retrospective cohort study of all calcaneal fractures surgically treated with either approach between January 2008 and January 2018. Anatomic restoration was assessed radiologically by the change in Gissane's and Bohler's angles and calcaneal width. Post-operative complications including metalwork removal were recorded. Results. 35 calcaneal fractures were managed surgically via either approach during this period (21 STA and 14 ELA). There was a statistically significant improvement in the radiological makers when the post-operative films were compared to pre-operative ones. When the post-operative films from the 2 groups were compared against each other, there was no significant difference (p< 0.05) in any of the radiological markers. In the ELA group, 2 patients (14.3%) developed deep infections requiring metalwork removal and 1 had delayed wound healing (7.1%). No deep infections occurred with the STA; 1 patient (4.8%) had a superficial infection, treated with antibiotics. Of patients who had metalwork in situ for more than 1 year, 37.5% of the STA group required removal due to pain compared to only 16.7% with ELA. Conclusions. We have moved from ELA to STA. Our results have shown no difference in restoration of calcaneal anatomy but with a decrease in post-operative wound complications including infection. However, we have shown an increase in metalware removal in the STA group and it is important to ascertain the cause and significance of this

Aims

A multicentre, randomized, clinician-led, pragmatic, parallel-group orthopaedic trial of two surgical procedures was set up to obtain high-quality evidence of effectiveness. However, the trial faced recruitment challenges and struggled to maintain recruitment rates over 30%, although this is not unusual for surgical trials. We conducted a qualitative study with the aim of gathering information about recruitment practices to identify barriers to patient consent and participation to an orthopaedic trial.

Introduction:. The dorsal closing wedge calcaneal osteotomy has been described for the treatment of insertional pathology of the tendo-achilles. The aim of this study was to evaluate the efficacy of the technique using outcome measures. Method:. This was a prospective case series. Patients were included if they had tendo-achilles insertional pathology (calcific tendonitis, bursitis or Haglund's deformity). A short extended lateral approach was used and a 1 cm dorsally based closing wedge osteotomy of the calcaneus performed. Fixation was with 2 staples. Patients were scored pre-operatively and at 6 and 12 months post-operatively using the VISA-A and AOFAS ankle-hindfoot scores. Results were analysed with the paired student t-test. Results:. Twenty five feet in 23 patients were enrolled in the study February 2011 – May 2013. 22 patients underwent the osteotomy (9 males and 14 females). Average age was 47.2 years (range 19–62 years). 12 feet have been followed up for 1 year, 6 for 6 months, 5 less than 6 months. Average VISA-A improvement was 27.87 points (−13–71) at 6 months p=0.001 and 38 (−13–81) at 12 months p=0.001. Average AOFAS improvement was 11 points (−8–31) at 6 months p=0.005 and 11 (−18–42) at 12 months p=0.04. 82.3% of patients would have the procedure again. Complications included minor wound problems (3), sural nerve symptoms (1) and plantar fasciitis (3). All complications have resolved. Conclusion:. The results of this study show that the use of the Zadek osteotomy of the calcaneus can provide consistent symptomatic relief from insertional Achilles pathology by altering the biomechanics of the tendon without disrupting the bursa. There is a small risk of minor complications, which should be included in the consent process

Introduction:. We report our 10-year experience of post-operative complications of calcaneal fractures treated by internal fixation and attempt to correlate these with previously cited patient risk factors. Methods:. All calcaneal fractures treated by internal fixation in our Major Trauma Centre between September 2002 and September 2012 were identified. Patient indices (age, gender, smoking status and pre-existing co-morbidities), time to surgery and method of surgery (open reduction and internal fixation (ORIF) versus closed reduction and percutaneous fixation) were recorded. Primary outcome was the incidence of wound infection requiring intravenous antibiotics and/or re-operation. Statistical analysis through Mann-Whitney-Wilcoxon testing and relative risk ratio calculations with 95% Confidence Intervals (CI) was performed. Results:. 98 calcaneal fractures in 92 patients were identified. 79 (80.6%) fractures occurred in males, 19 (19.4%) in females. 54 (55.1%) were smokers and 44 (44.9%) non-smokers. 18 (18.4%) were treated by closed reduction and percutaenous fixation and 80 (81.6%) by ORIF. 3 (3.1%) patients (all male) developed post-operative wound infection (RR 0.96, 95% CI 0.92–1.00), of which 1 was a smoker (RR 1.03 95% CI 0.95–1.11). All infections occurred in patients treated percutaneously (RR 6.33, 95% CI 3.99–10.08). There was no significant difference in mean time to surgery (p=0.069) and mean age (p=0.31) for those patients experiencing wound complications and those who did not. Conclusions:. This study reports an overall wound infection rate in keeping with current literature. There was no statistically significant increased risk of wound infection in smokers or male patients. All infections occurred in patients who had percutaneous treatment. These findings support the continued treatment of displaced calcaneal fractures by open reduction and internal fixation through a conventional extended lateral approach. There is no justification in denying surgery to males or smokers although these two factors have been cited as poor prognostic indicators in earlier studies

Introduction. Calcaneal osteotomy is often performed together with other procedures to correct hindfoot deformity. There are various methods of fixation ranging from staples, headed or headless screws or more recently stepped locking plates. It is not clear if one method is superior to the other. In this series we compare the outcome of various methods of fixation with particular attention to the need for subsequent hardware removal. Patients and Methods. A retrospective review of the records of a consecutive series of patients who had a calcaneal osteotomy performed in our unit within the last 5 years was undertaken. All patients had had their osteotomy through an extended lateral approach to their calcaneous. The subsequent fixation was performed using one of three methods; a lateral plate placed through the same incision; a ‘headless’; or a ‘headed’ screw through a separate stab incision inserted through the infero-posterior heel. Records were kept of subsequent symptoms from the hardware and need for metalwork removal as well as any complications. When screws were inserted the entry point in relation to the weight-bearing surface of the calcaneous was also recorded. Results. Sixty-three osteotomies were investigated of which 15 were fixed using a headed screw, 18 using a headless screw (acutrak TM) and the remaining 30 were fixed using a lateral plate. There was a 100% union rate regardless of method of fixation, no patient was investigated or subject to revision surgery for a suspected non-union. Overall 47% of the headed screws, 10% of the headless screws and 9% of the lateral plates were removed to address symptoms that were suspected to arise from the hardware. There was a 10% (3 from 30) rate of wound complication in the lateral plate cohort. In all these cases there was persisting discharge from the extended lateral wound that resolved with dressing and antibiotic therapy alone. Conclusions. Calcaneal osteotomies have a high union rate regardless of fixation method. Fixation using a headed screw is associated with a high rate of secondary screw removal and this is unrelated to the position of the screw in relation to the weight-bearing surface of the calcaneous. Hardware problems are less frequent in the ‘headless’ screw or the lateral plate groups; however in this series, the incidence of local wound complications was higher in the group fixed with a lateral plate

Aims

Arthroscopically controlled fracture reduction in combination with percutaneous screw fixation may be an alternative approach to open surgery to treat talar neck fractures. The purpose of this study was thus to present preliminary results on arthroscopically reduced talar neck fractures.

Talonavicular and subtalar joint fusion through a medial incision (modified triple arthrodesis) has become an increasingly popular technique for treating symptomatic flatfoot deformity caused by posterior tibial tendon dysfunction.

The purpose of this study was to look at its clinical and radiological mid- to long-term outcomes, including the rates of recurrent flatfoot deformity, nonunion and avascular necrosis of the dome of the talus.

A total of 84 patients (96 feet) with a symptomatic rigid flatfoot deformity caused by posterior tibial tendon dysfunction were treated using a modified triple arthrodesis. The mean age of the patients was 66 years (35 to 85) and the mean follow-up was 4.7 years (1 to 8.3). Both clinical and radiological outcomes were analysed retrospectively.

In 86 of the 95 feet (90.5%) for which radiographs were available, there was no loss of correction at final follow-up. In all, 14 feet (14.7%) needed secondary surgery, six for nonunion, two for avascular necrosis, five for progression of the flatfoot deformity and tibiotalar arthritis and one because of symptomatic overcorrection. The mean American Orthopaedic Foot and Ankle Society Hindfoot score (AOFAS score) at final follow-up was 67 (between 16 and 100) and the mean visual analogue score for pain 2.4 points (between 0 and 10).

In conclusion, modified triple arthrodesis provides reliable correction of deformity and a good clinical outcome at mid- to long-term follow-up, with nonunion as the most frequent complication. Avascular necrosis of the talus is a rare but serious complication of this technique.
