The patient was a 41-year-old blind male who accidently fell from a height, which caused left hip pain and limited activity. Two months prior, he had presented with ipsilateral femoral neck fracture due to falling from a standing height and was treated with closed reduction and cannulated screws fixation. Additionally, 34 years ago, the left thigh was subjected to a proximal femoral fracture, which was conservatively treated. A preoperative anteroposterior X-ray (a) and a lateral X-ray (b) demonstrated a left femoral intertrochanteric fracture, cannulated screws fixation for previous femoral neck fracture, and a proximal femoral angulation deformity due to the injury 34 years ago. CT radiographs (c) indicated a clear fracture line of the left femoral neck fracture (yellow arrow) and the ipsilateral femoral intertrochanteric fracture (red arrow). The cannulated screws were removed and the reshaped proximal femoral locking compression plate was used for fixation. Postoperative X-ray radiographs of the anteroposterior (d) and lateral view (e) 2 days after surgery. X-ray radiographs of the anteroposterior (f) and lateral view (g) 2 years after surgery indicated fracture union. The general functional outcomes at the 2-year follow-up (h, i)
