METHOD AND APPARATUS FOR SACROILIAC JOINT FIXATION

摘要

Disclosed is a fixation device for sacroiliac joint stabilization. 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 the ilium of the pelvis and the bone anchor is rotated into position within the sacrum. The proximal anchor is distally advanced with respect to the bone anchor to provide compression across the sacroiliac joint.

主权项

1. A bone fixation device, comprising:
an elongate body, having a proximal end and a distal end; a distal anchor on the distal end; a retention structure on the body, proximal to the anchor; a proximal anchor, moveably carried by the body; at least one complementary retention structure on the proximal anchor configured to permit proximal movement of the body with respect to the proximal anchor but to resist distal movement of the body with respect the proximal anchor; and an inner member disposed within the elongate body, the inner member comprising a distal end configured to abut the distal anchor when proximally retracted.
