Progression of Compression Type Femoral Neck Stress Fracture: Two Cases Report / 대한스포츠의학회지

ABSTRACT

The stress fracture of the femoral neck is an uncommon injury and delay in diagnosis occurs occasionally. It is generally classified as the compression type and the tension type. The compression type fracture of the femoral neck is stable, and could be treated nonoperatively. Tension type fracture is potentially unstable, and could require operative stabilization. The displacement of the femoral neck stress fractures has potential complications such as osteonecrosis of femoral head, malunion and nonunion. We have experienced two cases of compression type fractures that progressed to entire femoral neck despite conservative treatment with avoidance of weight bearing. These two cases shows even compression type of femoral neck fracture could further progress to entire femoral neck after conservative treatment, which could require operative treatment.
