A second plate section extends continuously from the first plate section. The second plate section has at least a third hole that is positioned to be offset from the first hole and the second hole in a direction that is anterior or posterior from the first hole and the second hole in a case where the longitudinal axis is aligned along a superior-inferior direction. The third hole is configured to receive at least one screw or at least one button for holding a suture at a position offset from the first line segment hole and the second hole in the anterior or posterior direction, for reducing the syndesmosis.

Abstract: The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device described herein is capable of being installed inside an intervertebral disc space at a minimum to no distraction height and for a fusion device capable of maintaining a normal distance between adjacent vertebral bodies when implanted.

Abstract: A two-part screw system includes an inner member and a cannulated outer member that may be pre-assembled with an inner member driver and an outer member driver to form a surgical assembly. A method of inserting the two-part screw system includes advancing the inner member into the bone by using the inner member driver, and advancing the outer member into the bone by using the outer member driver. The inner member acts as a guide for the outer member, and eliminates the need for a separate guide wire. The pre-assembled nature of the surgical assembly eliminates the need to sequentially remove and apply drivers and implant parts. The inner member and the outer member are configured to integrate into a substantially solid body when in a final alignment, thus forming a stronger implant than a cannulated screw.

Abstract: The cable-locking plate with screw allows for compression of bone fractures using a tensioned cable. The cable-locking plate with screw allows the use of a cable as a flexible bridging member, such as a cable, helps create compression while accommodating the unusual shape. The cable-locking plate with screw allows a surgeon to tension a cable through the plate, then grip the cable by tightening a screw associated with the plate. The compression is created is across the fracture, not around the bone, thus avoiding compression of nerve and blood vessels along the bone's surface. The cable is guided into an ideal position using cable channels, allowing the surgeon to concentrate on tension and screw compression. The plate and cable system are then left in the patient while the bone mends. The cable-locking plate with screw is either left permanently or removed during a later surgery.

The implant has a body with a bone facing surface and bilaterally protruding connecting means. The inserter has hooks that engage under the connecting means. The hooks and the rest of the inserter are proximal to the bone facing surface so that the implant may be fully seated against a bone surface while connected to the inserter.
