A rare case of bicondylar Hoffa fracture associated with ipsilateral tibial spine avulsion and extensor mechanism disruption

Abstract

【Abstract】Intra-articular coronal fractures (Hoffas fractures) of distal femur are rare. Although bicondylar involvement in these fractures has been reported in the litera- ture in association with high velocity traumata, the occurrence of these fractures involving extensor mechanism rupture and avulsion of ipsilateral tibial spine is extremely rare. To our acquaintance, such a fracture pattern has not yet been reported in the literature so far. In this article, we re- port one such case and discuss the importance of earlydiagnosis and prompt internal fixation in the management of such cases.We believe that these rare combinations of injuries should be treated aggressively by early open reduction and anatomic rigid internal fixation in order to achieve good recovery of function.
