Abstract
Chapter 20 discusses femur trauma and reviews the mechanism of injury and clinical features, imaging strategy, imaging characteristics, and classification and treatment options. Subtrochanteric, femoral shaft, and distal femoral fractures are discussed. Subtrochanteric fractures are usually high-energy fractures, but are also seen in osteoporotic patients after low-energy trauma and those on bisphosphonate treatment. Distal femoral fractures may be supracondylar, intercondylar, or condylar. Femoral shaft fractures may be associated with life-threatening trauma elsewhere. Atypical femoral fractures are briefly reviewed. Intraarticular extension of distal femoral fractures is important to note as this will affect management. Evaluation of femoral fractures begins with anterior-posterior (AP) and lateral radiographs of the femur.
