Femoral neck fracturesFemoral neck fractures occur most commonly in the eighth decade of life as a result of bone that is weakened by either osteoporosis or osteomalacia. The most common mechanisms of injury are either a fall that causes a direct blow to the greater trochanter or forced lateral rotation of the lower extremity (Bucholz et al., 2009). If the fracture is displaced, often the arterial supply to the proximal end of the femur is disrupted, thus creating an environment favorable to the development of either a nonunion or avascular necrosis.
