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.
