a The pre-operative radiographs of a 44-year-old woman showed sandwich AAD, C1 occipitalization and C2–3 and C5–6 congenital fusion. b-d Preoperative CT revealed the left C2 pedicle can accommodate a 3.5-mm screw (c), while the right pedicle was “thin”and occupied by VA. e. The odontoid invaded the foramen magnum, and ADI was abnormal (10 mm). f. The pre-operative mid-sagittal CT scan. g. The pre-operative MRI showed severe compression of the spinal cord. h. During the surgery: On the left side, C2PS was plated and connected with the occiput by a plate; On the right side, C2LS was inserted and connected with the occiput screws by a rod. Morselizedcancellous grafts harvested from the posterior iliac crest were bridged between the occiput and C2 lamina. i. The post-operative radiographs (AP). j. The post-operative radiographs (Lateral). k. The post-operative MRI showed adequate decompression. l. Postoperative CT (after 4 months) confirmed complete reduction and rigid fusion between occiput and C2. m. The postoperative CT showed the techniques included C2PS and C2LS
