  • Patent number: 3996931
    Abstract: A nailing apparatus for fractured femoral bones consisting of a sleeve member and a femoral fastening member, the latter having parallel slots opening through one end of the fastening member and being of different lengths. The sleeve is telescopingly engageable over the slotted end of the fastening member and is equipped with an inwardly projecting key for keying into one of the slots. The shorter slot limits movement of the key along the fastening member and the longer slot allows the sleeve member to be drawn onto the slotted end of the fastening member as far as desired. The end of the fastening member remote from the slots is equipped with anchoring means for anchoring to a femoral head and the sleeve member is equipped with a trochanteric plate for securement to both adjacent cortex portions by fastening means secured through the plate. The trochanteric plate may be disposed at any desired angle relative to the longitudinal axis of the sleeve member.
