STUDY DESIGN: We have retrospectively reviewed 11 chronic hemodialysis patients with cervical destructive spondyloarthropathy responsible for neural impairment 1 year after surgery and at last follow-up. OBJECTIVE: To evaluate clinical and radiologic outcomes, and necessity of vertebral block excision. SUMMARY OF BACKGROUND DATA: Destructive spondyloarthropathy of the cervical spine is associated with long-term hemodialysis for chronic kidney failure. Spinal cord compression and neurologic troubles occur in a few cases. Surgical treatment remains controversial because these are debilitated patients with multiple organ failures. METHODS: All 11 patients had unstable cervical spondylolisthesis, and 10 had kyphotic vertebral fusion involving at least 2 vertebrae. We performed interbody bone grafting (cement in 1 case) and stabilized with a plate. In 6 of the 10 patients with vertebral block, excision of the block was performed. RESULTS: No patients were lost to follow-up. One patient died 2 days after the operation. There were 2 other patients who required early surgical revision (i.e., a corporectomy followed by early graft expulsion). Bone healing settled in all patients. One year after surgery, patients had almost complete resolution of the pain and satisfactory neurologic recovery. Improvement was evaluated according to the Nurick classification. CONCLUSION: Functional and neurologic results were similar whether the patients did or did not undergo vertebral block excision, suggesting that stabilizing the unstable level may be sufficient in patients with neurologic impairment. Excision of spontaneous vertebral blocks should be avoided to minimize the morbidity of surgery in these debilitated patients with a limited life expectancy.
