Cervical Spine Surgical Vertebral Atlanto-axial Trans-articular Screw Fusion Fixation medical trial exhibits movies. Illustrates the surgical technique for performing an atlanto-axial trans-articular screw fusion. This procedure is used to fuse the C1 (atlas) and C2 (axis) vertebra together to control pain or increase stability at the C1-2 segment. It shows the posterior fusion preparation and wire fixation of the bone graft, x-ray position checks and finally wound closure. An atlanto-axial trans-articular screw fusion is done to realign and stabilize the first and second cervical vertebra. See the medical trial exhibits movies. This bone graft will fuse over three months to turn the two vertebrae into one solid bone. While the bone is fusing it is held still by two metal screws and wiring or rods.
