Radiographs revealed a valgus-impacted NOF fracture (Fig. 1a and b). Threads of all three cancellous screws passed the fracture line into the femoral head (Fig. 1c and d).Post-operative Garden's alignment index was satisfactory at 160  in the AP plane and 170  in the lateral plane.
(a and b) X-ray of new subtrochanteric fracture; (c-e) computed tomography scan delineating fracture line distal to inferior screw at region of lesser trochanter.

Radiographs and computed tomography (CT) imaging revealed a peri-implant subtrochanteric fracture with a fracture line originating distal to the inferior screw at the level of the lesser trochanter (Fig. 2a and e).
