DISTAL BONE ANCHORS FOR BONE FIXATION WITH SECONDARY COMPRESSION

摘要

Disclosed is a bone fracture fixation device (12), such as for reducing and compressing fractures in the proximal femur (10). The fixation device (12) includes an elongate body (28) with a helical cancellous bone anchor (34) on a distal end (32). An axially moveable proximal anchor (36) is carried by the proximal end (30) of the fixation device (12). The device (12) is rotated in to position across the fracture or separation between adjacent bones and into t he adjacent bone or bone fragment, and the proximal anchor (36) is distally advanced to apply secondary compression and lock the device (12) into place. The device (12) may also be used for soft tissue attachments.
