Subcapital fracture complicating an intertrochanteric fracture.

A previously undescribed type of fracture of the neck of femur occurred following intertrochanteric fracture fixation with a McLaughlin nail plate in an 80-year-old woman. This complication was probably caused by prolonged non-weight-bearing and inadequate fixation. The complication possibly could have been avoided by use of a dynamic hip screw and early weight-bearing.
