Cervical spondylotic radiculopathy (CSR) has been caused by instability and degenerative changes of cervical spine. We report the result of surgical treatment for CSR for 3 years. Material is 12 paients, 9 women and 3 men. The average age of the patients at the time of surgery was 51.8 (range, 26-70 years). The method of surgery is anterior fusion for 6 cases and enlargement of spinal canal by splitting of spinous process for 6 cases. We have judged 4 major symptoms. That is brachialgia, nape pain & occipitalgia, muscle weakness, and sensory disturbance. 11 cases of all have 4 major symptoms. Radiologically, there are 3 cases with instability. In 2 cases, pincer phenomenon is showed and developmental canal stenosis is demonstrated in 5 cases by plain X-P. High signal intensity of spinal cord is showed in one by MRI. Most involved spinal level is both C4/5 and C5/6. About aftected cervical spinal root, C6 root is 6cases and C5 root is 5. In anterior surgery, 4 cases is one level and 2 cases are 2 levels. In posterior intervention, hydroxylapatite block is used for 4 cases as spacer. Evaluation of result is according to Murakami's criteria. The average of improvement ratio was 90.9% in anterior cases and 78.9% in posterior cases. All cases were improved in symptom satisfactorily.
