ABSTRACT
OBJECTIVE:
To introduce a new technique using OsteoMed M3 titanium plate and screws for fixation of the posterior elements in the open position after expansive unilateral open-door laminoplasty and evaluate its clinical effect.METHODS:
Sixteen patients with multilevel cervical disc herniation and canal stenosis were treated with an expansive unilateral open-door laminoplasty using OsteoMed M3 plate and screws, and the follow-up period lasted for over 6 months.RESULTS:
Most of the patients had marked neurological improvement after the surgery. The mean Japanese Orthopaedic Association (JOA) score of the patients increased significantly from 9.06-/+2.380 (range 5 to 13) before surgery to 13.63-/+1.408 (range 11 to 16) at the final follow-up (P<0.005), with a mean recovery rate of 57.5%. One patient without postoperative neurological improvement underwent an additional anterior multilevel corpectomy. Bone fusion of the surgical lamina was achieved in all the cases without canal stenosis.CONCLUSION:
Unilateral open-door laminoplasty with OsteoMed M3 titanium plate and screw fixation can effectively maintain the expansion of the spinal canal and resist closure while preserving the spinal alignment and stability. This modified technique is easy to perform and is associated with a low complication rate.
