[Retrospective study of 50 cases of tibial pilon fractures in adults at the Department of Orthopedics of the University Hospital Center Habib Bourguiba, Sfax, Tunisia]. / Etude rétrospective de 50 cas de fractures du pilon tibial chez l'adulte dans le Département d'Orthopédie, Centre Hospitalier Universitaire Habib Bourguiba de Sfax, Tunisie.

Tibial pilon fractures are polymorphic fractures posing therapeutic and prognostic challenges. The purpose of this study is to examine the epidemiological profile of these fractures and to assess our findings from an anatomical and functional point of view. We collected data fom 50 medical records of patients treated for tibial pilon fractures and monitored over the period 2004-2013 at the Orthopedic-Trauma Department of the Habib Bourguiba University Hospital in Sfax. Functional outcomes were assessed using the Ankle-Hindfoot score. Radiological findings were used to determine fracture healing. Treatment was based on internal osteosynthesis in 30 cases, external fixation in 11 cases and on a combination of both techniques in 9 cases. At the end of this study, functional outcomes were good and very good in 36 cases. Thirty cases of fracture healing were reported, with 18 cases of vicious callus and two cases of pseudosteoarthritis. Therapeutic management of tibial pilon fractures is difficult in some cases. Solid osteosynthesis with anatomical reduction is the only therapeutic option to secure a satisfactory functional outcome.
