Single-Incision Peroneal Tendon Repair With Concomitant Modified Dwyer Calcaneal Osteotomy: Report of 15 Cases With Plate Fixation.

Background: Addressing hindfoot varus via calcaneal osteotomy with simultaneous peroneal tendon repair from a single incision has not been thoroughly assessed. Some concerns with one incision are wound complications, nerve damage, and symptomatic hardware.
Methods: Patients operated on by one surgeon May 2012 to January 2022 were retrospectively reviewed with minimum 2-year follow-up via in-person visit, telephone, and chart review. Patients with peroneal tendon repair in conjunction with a modified Dwyer (with lateral shift) osteotomy fixated with a laterally applied locking plate were included. Those whose osteotomies were fixated with posteriorly applied screws were excluded.
Results: Fifteen patients were assessed, 13 males and 2 females, average age 56.9 ± 9.9 years. There were no wound complications or nerve injuries. One patient elected to have plate removal. There was 1 deep vein thrombosis. Return to activity including sports was 5.3 ± 1.3 months. On average, postoperative Roles and Maudsley and AOFAS hindfoot scores improved to "significant from pre-treatment" 11 with "excellent" results.
Conclusion: Peroneal tendon repair can be performed through the same incision as a modified Dwyer calcaneal osteotomy to address hindfoot varus deformity. In this series, there were no wound or nerve issues.
