Factors affecting the surgical results of expansive laminoplasty for cervical spondylotic myelopathy.
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.
