A Feasibility Study of a New Muscle Sparing “C3 Dome-Hybrid Open-Door Laminoplasty”: A Surgical Technique, Clinical Outcome, and Learning Curve Description

This study reports the design and feasibility of a new hybrid laminoplasty technique aimed to reduce the complications of the conventional laminoplasty, with the incorporation of C3 dome-osteotomy, an open-door C4–6 instrumented laminoplasty and C7 cephalad dome-osteotomy. Summary of Background Data. Recent findings showed that the preservation of the dorsal muscles attached at either C2 or C7 cervical spine reduced the complications of C3–C7 open-door laminoplasty. Methods. A retrospective review of consecutive patients who underwent the C3 dome-hybrid laminoplasty technique by a single surgeon with at least 2 years follow-up was performed. The surgical technique was described in detail. Clinical and radiological outcome data were analyzed. Results. Twenty six patients with cervical cord compression who underwent C3 dome-hybrid laminoplasty were recruited. The mean postoperative follow-up was 45.6 ± 24.7 (24–101) months. Significant improvements were observed in the preoperative to postoperative mean Japanese Orthopaedic Association (JOA) score (13→15, P
