An AP radiograph of the pelvis and right hip reveals a nonunion neck of femur fracture with varus deformity, assessed at 81 degrees Pauwels angle. Hardware that has been bent. (b) Intraoperative image shows pseudoarthrosis with lysis and scelorosis, as well as impending hardware failure. (c) Visualization of Pauwels' osteotomy execution during surgery. (d) The wedge bone was leveraged into the bone defect by 7 mm cannulated screws that were removed. (e)-(f) Radiographs depicting the postoperative outcome and a 12-month follow-up.

This was easily achieved because of the inactivity atrophy after prolonged immobilisation and pain (Figure 1).

Meanwhile, Southwick osteotomy was carried out in 13 patients as a transverse cut just below the level of the lesser trochanter (Figures 2 and 3).
