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.
