Anterior Cervical Plating after Corpectomy: A Report of 60 Cases

Background and Objectives: Anterior cervical plating is one of the most useful methods for treatment of cervical collapses. This study was conducted to determine the indications, safety, efficacy, and complications associated with performing corpectomy for anterior decompression of neural elements. Materials and Methods: Between 1993 and 1999, 60 patients undervent cervical corpectomy for treatment of degenerative spondylotic diseases (8 cases), ossification of posterior longitudinal ligament (PLL) (2 cases), fractures of vertebral body (40 cases), tumor (7 cases), and infection (3 cases). Eight cases presented with myelopathy, 10 cases with radiculopathy, 2 cases with neck muscle spasm and 40 cases with radiculo-myelopathy. Fifty patients were treated with one-level corpectomy and 10 patients with two-level corpectomy, and all of them underwent discectomy at both upper and lower levels. In all cases autograft (iliac crest) was used and fixation was performed with an anterior plate-screw system. Results: There was no operative mortality and new neurological sequela were not encountered. Postoperative hoarseness, dysphagia, and pain at the operation and graft sites, were transient. During the procedure, the vertebral artery was injured in one patient, that undewent ligation. The fusion rate was 91.7% . All patients presented with pain, improved completely (100%), as did 80% of the patients presented with radiculopathy and 60% of the patients presented with myelopathy. Conclusion: Corpectomy has an important role in the management of various traumatic, degenerative, neoplastic or infectious conditions of cervical spine. In this study, radiculopathy improved in all cases and myelopathy reversed in most patients, following treatment.
