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

Background. Whereas arthroscopic arthrodesis of the ankle is commonplace and of the subtalar joint is established, reports of arthroscopic talo-navicular fusion are a rarity. Aim. To review a case series to establish if arthroscopic talo-navicular arthrodesis is a feasible surgical option. Methods. Arthroscopic decortication of the talo-navicular joint is performed via x1-2 sinus tarsi portals and x1-2 accessory talo-navicular portals using a standard arthroscope and a 4.5 barrel burr. Internal fixation is by a 5mm screw from the navicular tuberosity and x2 headless compression screws introduced under image intensification from the dorsal navicular to the talar head. Between 2004 and 2017 a consecutive series of 164 patients underwent arthroscopic hindfoot arthrodeses of which 72 involved the talo-navicular joint. Only 13 procedures were of that joint alone in unsullied feet. The medical records of these 13 patients were reviewed to assess radiological fusion, complications and improvement of pre-operative state. Results. All Talo-navicular joints were successfully decorticated. All united radiologically by a mean 4.4 months (range 3–8). There were no major complications. All patients reported improvement to their pre-operative symptoms but one patient developed lateral column pain requiring fusion. Conclusions. Arthroscopic Talo-navicular arthrodesis is technically feasible with good rates of union. Complications were rare, making the technique attractive when encountering a poor soft tissue envelope. The surgery cannot be used if bone grafting is required. Long term discomfort can arise from adjacent joints. Accurate alignment is critical

Aims

The aim of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a percutaneous extra-articular reverse-L chevron (PERC) osteotomy.
