OBJECTIVE: To evaluate the therapeutic effects of fixation and fusion with lateral mass screws of the atlas and vertebra dentata pedicle screws for the treatment of upper vertebral instability.
METHODS: Ten patients with atlantoaxial instability, including 3 with old odontoid fracture and 7 with fresh odontoid fracture (Aderson II) received surgeries for fixation and fusion with lateral mass screws of the atlas and vertebra dentata pedicle screws.
RESULTS: No spinal cord or vertebral artery injuries occurred in these patients after the surgery. The follow-up duration ranged from 3 to 15 months with an average of 8 months. The postoperative JOA scores were from l3.2 to l6.8, with an average of l4.8. Clinical improvement was achieved in 87.5% of the patients, and the implanted bones all fused successfully without internal fixation rupture or mobilization.
CONCLUSION: Lateral mass screws of the atlas combined with vertebra dentata pedicle screws allows three-dimensional fixation for treatment of atlantoaxial instability.
