Combined Subtalar Distraction Arthrodesis with Peroneus Brevis Tenotomy for Posttraumatic Subtalar Arthritis

Abstract Background Subtalar distraction arthrodesis is advocated as a salvage procedure for isolated posttraumatic subtalar arthritis. This study aimed at evaluating combined subtalar distraction arthrodesis with peroneus brevis tenotomy for such cases. Methods Twenty patients with isolated posttraumatic subtalar arthritis managed by combined subtalar distraction arthrodesis and peroneus brevis tenotomy were reviewed for a retrospective study. The American orthopaedic foot and ankle society [AOFAS] hindfoot scoring, talocalcaneal height [TCH], talocalcaneal angle [TCA] and heel valgus angle [HVA] were used for both pre and postoperative assessments. Results The mean postoperative [TCH] [70.3 ± 1.9 mm] was statistically better than the preoperative value [64.7 ± 2.2 mm] [p  Conclusions Applying this technique for isolated posttraumatic subtalar arthritis with peroneal tendinitis improved both lateral retromalleolar swelling and deformity correction.
