Incidence of tendon entrapment and dislocation with calcaneus and pilon fractures on CT examination

Objective To examine the association between tibial pilon and calcaneal fracture classification and tendon entrapment or dislocation. Materials and methods After institutional review board approval, we retrospectively reviewed consecutive CT scans with calcaneal or pilon fractures from 5 years at a level 1 trauma center. We categorized calcaneal fractures according to the Sanders classification, and pilon fractures according to the Ruedi and Allgower and the Arbeitsgemeinschaft für Osteosynthesefragen-Orthopaedic Trauma Association (AO-OTA) classifications. Ankle tendons were assessed for dislocation or entrapment. Fisher’s exact test was used for statistical analysis with significance at p
