ABSTRACT:
The instant invention provides both a device and a method for treatment of a fractured neck of a femur. The device is such that it is inserted inside the broken femur and urges the two halves together so that the bone will unite and heal by natural growth processes. Unlike its predecessor the instant invention can be withdrawn from the femur once sufficient healing has taken place and the bone will continue to repair itself for all practical purposes to an extent as if no fracture had occurred.
