Abstract:
Cavovarus foot is a complex 3-dimensional deformity. Clinical history, physical examination, and comorbidity assessment are essential for preoperative evaluation. In severe cases, ankle or tibiotalocalcaneal arthrodesis can provide symptomatic relief and result in a plantigrade foot. This article emphasizes the importance of weight-bearing computed tomography for surgical planning and presents the authors' preferred technique for tibiotalocalcaneal, which includes a novel curved anterolateral incision, partial fibular onlay bridging graft, and patient-specific instrumentation for forefoot deformity correction. The tips and tricks aim to assist surgeons in better treating these challenging patients while optimizing preoperative planning.
