Abstract
The authors report their experience in the treatment of cervical spondylotic myelopathy by multiple subtotal vertebrectomy and fusion. There were 27 cases with a mean age of 66.9 years. The clinical assessment was carried out using both the Nurick and the Japanese Orthopaedic Association (JOA) grading pre- and post-operatively at 6 months. The post-operative radiological assessment was done at 3 and 6 months. Two cases died from unrelated medical problems. There were three cases of graft dislodgement. Clinical improvement was detected in 80% of cases using the Nurick grading and in 88% of cases using the JOA scoring. No cases deteriorated neurologically after operation. Bony fusion was achieved in 96% of the surviving cases by 6 months. Multiple subtotal vertebrectomy and fusion is therefore an effective method for the treatment of cervical spondylotic myelopathy.
