Treatment of degenerative cervical disc disease with uncoforaminotomy--intermediate clinical outcome.
BACKGROUND
Anterior cervical uncoforaminotomy (uncoforaminotomy) is an operative method intended to preserve the functional motion segment of the cervical spine while removing the underlying pathology. Controversy exists concerning the patients best suited for this treatment modality. Furthermore, no long-term outcome analyses have been published.


METHODS
Between November 2002 and June 2004, 96 patients underwent single-level uncoforaminotomy in our neurosurgical department for the treatment of cervical radiculopathy. The patients were divided into three groups: A, soft disc; B, hard disc; C, hard and soft disc. Follow-up was performed 2 years after surgery. Clinical outcome was classified according to Odom et al. and to the cervical Oswestry and 11-point box scales for arm and neck pain.


RESULTS
Ninety patients (92%) underwent intermediate follow-up examinations at an average of 33 months after surgery. Forty-nine patients were in group A, 24 in group B, and 17 in group C. At discharge, 98% of those in group A, 96% in group B, and 94% in group C showed excellent or good results. In two patients revision surgery was performed within 4 weeks due to recurrent disc herniation. In one patient revision was carried out due to a subcutaneous hematoma. In group B one case of vertebral artery injury occurred. Additionally in one patient of this group revision surgery was performed due to inadequate decompression of the neural foramen. At follow-up 94% of the patients in group A, 89% in group B, and 87% in group C had excellent or good results. The scores on the cervical Oswestry scale and the 11-point-box scale showed no significant differences among the groups.


CONCLUSIONS
Uncoforaminotomy, especially in patients with soft-disc pathologies, is a good operative method for the treatment of radicular pain.
