Redisplacement of nailed femoral neck fractures: 4-year follow-up of 110 cases

In 110 femoral neck fractures, we measured the articulotrochanteric distance and the anteroposterior position of the femoral head, preoperatively, postoperatively, and at a minimum follow-up of 2 years. In displaced fractures the size of the displacement could not be used to predict future incidence of fracture redisplacement or femoral head necrosis.
