Femoral Neck Aneurysmal Bone Cyst Treated with Articulated Distraction and Grafting

The proximal femur and acetabulum are frequent sites for benign, active, and aggressive lesions. The risk of pathologic fracture is increased when a bone-destroying pathology involves an anatomic location such as the hip joint that undergoes profound mechanical loading. If the destruction involves a large area around the joint, secure fixation cannot be achieved with internal fixation implants. In this case, a patient with aneurysmal bone cyst in the femoral neck, who was treated with articulated hip distraction, is presented. Curretted area was protected with a external fixator, until the bone union is achieved.
