title: Subcapital femoral neck fracture after fixation of an intertrochanteric fracture with a proximal femoral nail: a report of two cases.
abstract: Subcapital femoral neck fractures are a rare complication after fixation of an intertrochanteric fracture with a proximal femoral nail. We report 2 such cases where the patients had severe osteoporosis, based on Singh's index and pathological findings. In one case there was a technical error leading to a tip-apex distance of more than 20 mm, but osteoporosis appeared to be a more significant cause than any technical problems.
