Intramedullary hip pin and cortical plate

An intramedullary pin, comprising:

• an elongate shaft having a longitudinally extending groove and a threaded portion formed intermediate its ends, the shaft having an enlarged, flattened end;
• an expansible cage adapted to be secured to the shaft, the cage including a first section in the form of a ring encircling the shaft, the ring including a boss extending into the groove, the first section being a generally concave or conical basket including a pair of fingers having reversely bent end portions as well as a pair of legs having openings formed near their ends, the fingers and legs alternating circumferentially of the ring and being spaced 90 degrees from each other, the cage also including a second section, the second section having a generally concave or conical basket the generally concave or conical baskets of the first and second sections having their concave sides facing one another, wherein the fingers extend through openings in the legs to form an interlocking cage;
• the bosses of the first and second sections being axially aligned for engagement with the longitudinal groove in the shaft;
• a nut engagable with the threads on the shaft and with one of the sections such that, upon tightening the nut, the sections are clamped between the nut and the enlarged end and are compressed axially, thereby expanding the fingers radially outwardly of the shaft;
• an elongate section securable to the lateral cortex of the shaft of a femur;
• and
• a tubular portion positioned at an obtuse angle with respect to the longitudinal axis of the elongate section, the tubular portion adapted to receive the shaft in sliding, non-rotating relationship.
