Disclosed is a fixation device for spinal fixation. The fixation device includes an elongated body comprising a bone anchor at a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. In one embodiment, the device is inserted through a first vertebra and the bone anchor is rotated into positioned within a second vertebra. The proximal anchor is distally advanced with respect to the bone anchor to provide compression across the first and second vertebra. In other embodiments, the device is used to secure stabilization devices across two or more vertebra.

Method and apparatus for spinal fixation

Disclosed is a fixation device that includes an elongated body including a bone anchor at a distal end. An axially moveable proximal anchor is carried by the proximal end of the fixation device. In one embodiment, the device is advanced through a spinous process of a first vertebra, inserted through the first vertebra and the bone anchor is rotated into position within a second vertebra. The proximal anchor is distally advanced with respect to the bone anchor to provide compression across the first and second vertebrae.

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