Arthroscopic reduction and internal fixation for fracture of the posterior process of the talus (Shepherd’s fracture): a case report

Abstract

Abstract Introduction Fracture of the lateral tubercle of the posterior process of the talus (Shepherd fracture) is an uncommon injury seen in sport. It is secondary either to indirect trauma on the plantarflexed foot or to high-impact direct trauma. The fracture can be missed with conventional X-rays and therefore advanced imaging methods such as CT scans are usually warranted for management planning. There is a low threshold towards surgical management in the displaced or comminuted case as the delayed functional outcome with conservative treatment is frequently sub-optimal with long-term pain, degenerative changes and non-union. In this regard, recent years saw an increasing interest in the role of minimally invasive approaches for Shepherd´s fracture treatment, such as arthroscopic reduction and internal fixation (ARIF). Case report We present a case of a 27-year-old white male professional football player from Serbia who had Shepard fracture and successfully managed with arthroscopic osteosynthesis. The technical approach is detailed with posterior ankle arthroscopy offering the advantages of a minimally invasive approach with low morbidity and a rapid return to regular sporting activities. Conclusion The utilization of the 2-port arthroscopic approach this method enables the direct observation of the articular surface along with the corresponding fracture lines, thereby affording the surgeon the chance to achieve accurate reduction via a minimally invasive soft tissue aperture. We advocate that Arthroscopic reduction and internal fixation (ARIF) is a reliable method for the fixation of Shepherd's fracture in the hands of experienced ankle arthroscopists.
