Introduction: We investigated the short-term clinical outcomes of 15 patients who underwent double-door cervical laminoplasty using a new titanium plate (CENTERPIECE, Medtronic).
Methods: Fifteen patients (nine men and six women) underwent double-door cervical laminoplasty using a new titanium plate from March 2021. We investigated the operative time, blood loss, intraoperative and postoperative complications, Japan orthopaedic association (JOA) score before surgery and 6 months after surgery, mean C2-7 mid-position angle immediately after surgery and 6 months after surgery, and hinge union on plain computed tomography after 6 months.
Results: The mean duration of the operation was 106 minutes (76-138), and the mean blood loss was 109 cc (30-339). Because the screw failed, one vertebral arch was used as an HA spacer. One case of postoperative C5 paralysis and one of screw backout was observed. The mean C2-7 mid-position angle immediately after surgery was 4.9°, and 6 months later it was 6.3°. The JOA recovery rate was 68.4% 6 months after surgery, and the hinge union rate was 77%.
Conclusion: Despite technical challenges, this surgical procedure is relatively easy and achieves sufficient early stability. Therefore, this innovative technique could be useful for double-door cervical laminoplasty.
