Purpose: to evaluate and compare clinical, functional and quality of life (QOL) outcomes after two types of surgical approach for single level cervical disc herniation: anterior cervical discectomy and fusion (ACDF) with cage and cervical artificial disc replacement (C-ADR). Method: 119 patients with cervical disc herniation underwent surgery from January 2007 to December 2010; 55 patients were included in the study (27 ACDF, 28 C-ADR). We performed: a pre and postoperative clinical evaluation of cervicobrachial pain, motor and sensory deficit in the upper limbs; afunctional and QOL evaluation with self assessment scales (VAS, NPNQ, SF-36); a postoperative instrumental evaluation of cervical ROM and pain. Mean follow-up period was 24 months. Results: After surgery both groups showed clinical, functional and QOL improvement. No pre and postoperative differences were found between the groups. The postoperative instrumental evaluation showed a globally reduced cervical ROM and a decreased pain threshold in comparison with normal values in both groups. Conclusion: Our results demonstrate the clinical equivalence of the two surgical techniques and the satisfaction of the two groups of patients two years after surgery. Although functional changes persist after surgery they do not affect quality of life.
