Cervical Spondylotic Myelopathy Release by Unilateral Open-Door Laminoplasty with Miniplate Alone: Three Years Follow-up

Abstract

Objective: Cervical spondylotic myelopathy (CSM) is a common degenerative spine disease that requires surgical intervention if conservative failed. Currently, there is interest in various technical of laminoplasty. To review outcome of patients who underwent single-door cervical laminoplasty using titanium miniplates alone. Materials and methods:The author performed surgery in patients with CSM by unilateral open-door laminoplasty, which allows through decompression of the cervical spinal canal. Pain was measured with a visual analog scale (VAS). Surgical outcome was analyzed with the modified Japanese Orthopaedic Association (mJOA) score.Results: Visual analog scale scores and mJOA were signi ficantly improved at 1, 2 and 3 years followup compared to preoperative levels. Recovery rate mJOA score 27,7%, excellent pain relief (100% of initial VAS score). Conclusion:Opendoor laminoplasty is easily applied for young spine surgeon, allows good field visualization and decompression, single-door cervical laminoplasty using miniplates alone is a safe technique and achieves a high hinge union rate, good canal decompresion and neurological recovery.
