An artificial joint includes a first joint assembly and a second joint assembly. The first joint assembly is adapted to be connected to a first bone and has a first contacting surface, wherein the first contacting surface includes a first convex arc surface, a second convex arc surface, and a third convex arc surface. The second joint assembly is adapted to be connected to a second bone and has a second contacting surface, wherein the second contacting surface is in contact with the first contacting surface and includes a first concave arc surface, a second concave arc surface, and a third concave arc surface, and the first concave arc surface, the second concave arc surface, and the third concave arc surface respectively correspond to the first convex arc surface, the second convex arc surface, and the third convex arc surface.

An adjustable vertebral spacer includes a spacer body, a movable member coupled to the spacer body, an adjustment ring mounted on the spacer body and rotatable to move the movable member and to further adjust the combined height of the spacer body and the movable member, a lock ring mounted on the spacer body for locking the movable member to the adjustment ring, and a top endplate coupled to the movable member at the top and tiltable to fit the angle of the adjacent upper vertebral body during surgery operation.

Adjustable vertebral spacer for vertebral reconstruction

A vertebral fixation plate assembly for insertion into the resection site between two vertebrae of a patients vertebral column and fixation to front or lateral side of the two adjacent vertebral bodies above and below the resection site by means of surgical implantation is disclosed to include a fixation plate that has a plurality of round holes and elongated holes and an opening on the middle, a plurality of bone screws respectively inserted through the round holes and elongated holes for fastening the fixation plate to the patient's vertebral column, and a cage affixed to the opening on the fixation plate and holding holes cut through the periphery for bone fusion and grow. The cage is linked to a vertebral spacer for artificial vertebrae by means of bone fusion to prevent vertebral sinking or slipping of the vertebral spacer and to improve bone fusion efficiency.
