title: Factors affecting the surgical results of expansive laminoplasty for cervical spondylotic myelopathy.
abstract: We studied the outcome of expansive laminoplasty in 37 patients with cervical spondylotic myelopathy. Patients were divided into two groups according to the recovery rate (RR) - a 'good' group ( n=19), and a 'fair' group ( n=18). Patients in the good group showed a greater pre-operative Japanese Orthopaedic Association (JOA) score, a greater compression ratio, and a larger Pavlov ratio ( P<0.05). The presence of high signal intensity on MRI proved to be of no prognostic importance.
