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

53. A method of aiding bone fusion between first and second vertebral bodies of the spine, comprising the steps of:
-
advancing a fixation device through the first vertebral body in the direction of the second vertebral body;
rotating at least a distal anchor of the fixation device to secure the fixation device to the second vertebral body; and
axially advancing a proximal anchor distally along the fixation device to engage the first vertebral body. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)
