The treatment of spondylotic cervical myelopathy by multiple subtotal vertebrectomy and fusion.

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.
