Extract

A coronal plane fracture of the femoral condyle (creating a so-called Hoffa fragment) has been well described in association with fractures of the supracondylar-intercondylar region of the distal part of the femur1. This fracture has implications with regard to preoperative planning, the choice of surgical approach, implant selection, and functional outcomes.Coronal plane fractures of the distal part of the femur are markers of high-energy injury mechanisms. Their presence warrants a thorough workup for other injuries associated with high-energy trauma such as fractures of the spine, pelvis, femoral neck, tibial plateau, ankle, and calcaneus. A Hoffa fracture can often be missed on plain radiographs. Nork et al. showed that up to 30% of coronal plane fractures were missed on plain radiographs of distal femoral fractures, often necessitating the use of computerized tomography for identification and preoperative planning2.
