Perioperative Complications and Radiographic Outcomes Following Cervical Laminoplasty: A Review of 105 Cases from a Single Academic Center

-OBJECTIVE: To assess complications and to compare preoperative and postoperative radiographic measures in patients who underwent cervical laminoplasty.-METHODS: We evaluated patients undergoing cervical laminoplasty between 2011 and 2022 at an academic medical center. Patient demographics, intraoperative and postoperative complications, and preoperative and post-operative radiographic parameters were recorded.-RESULTS: Of 150 patients undergoing cervical laminoplasty during 2011e2022, 105 met the inclusion criteria. We identified 22 (21.0%) adverse events in 20 patients: 4 intraoperative (3.8%), 10 perioperative (9.5%), and 8 delayed postoperative (7.6%). Among adverse events, 13 (12.4%) were judged to be minor and 9 (8.6%) were judged to be major complications. Revision surgery was required in 6 (5.7%) patients. Both preoperative and postoperative cervical spine radiographic imaging was available in 47 (44.8%) of the 105 patients. Mean preoperative and post-operative C2-7 Cobb angles were 14.7 degrees and 12.3 degrees, respectively (P = 0.04). Mean preoperative and postoperative sagittal vertical axis measurements were 29.2 mm and 33.3 mm, respectively (P = 0.07). Mean preoperative and postoperative T1 slopes were 32.3 degrees and 30.2 degrees, respectively (P = 0.07).-CONCLUSIONS: Cervical laminoplasty carries a significant risk of adverse events, the majority of which are mi-nor, and has a low rate of reoperation (5.7%). The procedure does not result in significant changes in sagittal vertical axis or T1 slope. Cervical laminoplasty remains a valuable surgical option for selected patients with cervical myelopathy.
