Endoscopic lateral calcaneal ostectomy for calcaneofibular impingement.

Lateral calcaneal bulging after conservative treatment of calcaneal fracture can result in calcaneofibular impingement or shoewear problem. We describe an endoscopic lateral calcaneal ostectomy. Through the anterolateral, middle subtalar portals, and a plantar portal, the soft tissue envelop is stripped from the bone and the posterior facet cartilage can be accurately assessed. The lateral cortical bulge is burred with an acromionizer and the degenerated cartilage debrided. With this approach, the integrity of the soft tissue envelop is preserved and the amount of cartilage debridement needed is accurately determined.
