Measurement of the femoral neck angle (*) compared to the contralateral side (°), defined as the angle between the femoral neck axis and the bisecting line of the femoral shaft (a). The tip-apex distance (TAD) was defined as the calibrated summation of the distance between the tip of the SHS and the apex of the femoral head on anteroposterior and (not demonstrated) lateral radiographs (mm) (b), and the angle between SHS and ASR in the frontal plane (#) (c) and the axial plane (x) (d) by using biplanar conventional radiographs, six weeks postoperatively.
