Abstract

See full text

Compression hip screw apparatus comprising a lag screw, a hip plate, a compression nut and a locking assembly. The lag screw is inserted through the barrel of the hip plate after the hip plate is installed which eliminates the need to find a lag screw buried within the femur. Keyless construction further aids assembly. The locking assembly frictionally locks together the lag screw, the hip plate and the compression nut.
