Cervical foraminotomy: an effective treatment for cervical spondylotic radiculopathy.

Between 1983 and 1994, posterior cervical foraminotomy as described by Frykholm was performed on 89 patients with exclusively radicular symptoms caused by cervical osteophytes. The main presenting feature was arm pain. Objective neurological signs were present in 50% of the patients. At mean postoperative follow-up of 8.6 months, 95.5% of patients reported excellent or good results, while 4.5% were not improved. No patient was rendered worse following the procedure. There were no deaths and the complication rate was 2.2%. Further surgery for recurrent root symptoms was required by 6.7% of patients. Our findings are in keeping with the good results and low complication rate of this procedure as described in other studies. Informal inquiries suggest that this procedure is not widely used, at any rate in the United Kingdom, and we present this series in order to emphasize the efficacy and safety of this procedure.
