OPTCS fixation for FNF in a 47-year-old female complicated by femoral neck shortening. A AP pelvis radiograph demonstrating the uninjured proximal femur was outlined with the neck-shaft angle labeled. B 6-month postoperative radiograph demonstrates fracture union with femoral neck shortening and varus displacement. The outline of the uninjured (solid line) overlapped on the fracture side (dotted line) is provided for comparison. The screw lateral withdrawal could be detected
