The purpose of our study was to determine if there was an increased incidence of femoral acetabular impingement (FAI) in patients presenting with femoral neck stress fractures. We evaluated the imaging studies of patient presenting with stress injuries of the femoral neck for features to suggest either cam or pincer-type FAI. Our results suggest that patients with bony abnormalities associated with pincer impingement, such as coxa profunda and acetabular retroversion, may be at increased risk of developing stress fractures. Over-coverage of the femoral head may place additional stresses on the femoral neck, predisposing an athlete to stress fracture
