Bipartite Talus: Arthroscopic Resection – Case Report

Abstract

Background: Bipartite talus is a rare entity. The etiology is uncertain. The definition is a large bone fragment that occupies the posterior portion of the talus and reaches the posterior subtalar joint. Case Report: We report a symptomatic bipartite talus in a female patient, 41 years old, treated with arthroscopic resection. Discussion: Posterior hindfoot arthroscopy has gained more popularity in the treatment of foot and ankle pathologies. Indeed, this is a secure and useful tool for the surgeon. In this report, we described the use of this technique for resection of a large bone fragment (bipartite talus). Conclusions: We present in detail the arthroscopic resection of a bipartite talus. This is an unusual pathology and a differential diagnosis for posterior impingement. We believe that arthroscopic resection of the bone fragment of the bipartite talus is a safe procedure, with less morbidity for the patient, compared with open resections. Level of Evidence: Level V—technique description.
