Kim, Chung, Jeon, Shim, Yoon, and Kim: Traumatic Femoral Head Fracture without Hip Dislocation - A Case Report -

Abstract

The incidence of femoral head fracturesafter posteriorhip dislocation is approximately 5-15%, and femoral head fractures are highly associated with posterior dislocation. Femoral head fractures can cause avascular necrosis of the femoral head or post-traumatic osteoarthritis; therefore, diagnosis and appropriate treatment is important. We present a case of femoral head fracture without hip dislocation, as well as a literature review.
