Abstract
Disclosed is a fracture fixation device, for reducing and compressing fractures in a bone. The fixation device includes an elongate body comprising a first portion and a second portion that are detachably coupled to each other. The first portion defines a helical cancellous bone anchor and the second portion defines a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device and is rotationally locked to the first portion. The device is rotated into position across the femoral neck and into the femoral head, and the proximal anchor is distally advanced to lock the device into place. The second portion is then detached from the first portion.
