An intramedullary fixation device for the proximal part of the femur. Nine years' experience.

Nine years' experience with a combined intramedullary rod and triflanged nail in eighty-four non-pathological fractures in the subtrochanteric region of the femur is reported and a system of classifying these fractures based on morphology is offered. The appliance was successful in permitting early mobilization of patients and afforded a high rate of union of the fractures. The problems of varus displacement of the distal fragment and protrusion of the device into the joint were not encountered, and there was only one mechanical failure.
