Spinous process splitting laminoplasty was performed on 52 patients with cervical myelopathy. We evaluated the surgical results of laminoplasty on operating time, blood lose, JOA score, alignment of the cervical spine, and postoperative complications. Clinical evaluation based on the JOA score indicated improvement from 8.5 points preoperatively to 12.1 points postoperatively. Postoperative complications were axial symptoms (4 cases), epidural hematoma (1 case), and liquorrhea (4 cases). Spinous process splitting laminoplasty is an effective procedure for cervical myelopathy.
