The basic treatment of cervical spondylotic radiculopathy and myelopathy is conservative including bed rest, cervical traction, epidural block and nerve root block. The cases of cervical spondylotic radiculopathy well responded to these methods of treatment. So there are very few cases which need operative treatment. According to Hirabayashi, we have determined the indication of operative treatment as foolows:
1. Severe radiating pain in the arm which doesn't improve in spite of 3 or 4 weeks of conservative treatment,
2. Recurrence of symptom, and
3. severe muscle atrophy and fatigability in the arm.
We have been experienced four cases which showed above symptoms and were operated upon.
