a Postoperative lateral radiograph measuring postoperative shaft angle (α) at fracture level. b Postoperative lateral radiograph measuring ventral (x) dislocation at fracture level. c Measurement of the CCD-angle: M = center of the femoral head, A = lateral point at the narrowest part of the femoral neck, B = point at medial femoral neck (through 2nd arc of a circle), 1 = femoral neck axis (vertical reference line to A-B through M), 2 = femoral shaft. d Anterior-posterior radiographs at 6 weeks, 3 months (after change of distal locking bolts) and 6 months postoperative: Radiographic measurements of the leg length shortening
