Early Bony Healing of Cervical Laminoplasty Hinge

Patrick Fransen, Bart Depreitere


Cervical laminoplasty is progressively gaining attention as a valuable option to treat cervical spondylotic myelopathy, allowing spinal cord decompression without fusion and producing outcomes comparable or superior to laminectomy. We report the early healing of a laminoplasty hinge after infection and removal of the metallic implants. We report the observation of a 69 year old patient presenting with cervical myelopathy, treated with a C6C7 open door laminoplasty. Early S. Aureus infection necessitated early removal of the laminoplasty implants.  During the operation, the uplifted posterior arches seemed stable. The metallic supports were removed and no further surgical action was performed. The infection healed and the patient did well afterwards. The two years radiological follow-up showed no collapse of the lamina. This observation may indicate that the laminectomy hinge can heal as early as two months after surgery. If this is the case, the metallic spacers could be replaced by shorter-lived resorbable implants.
