[Posterior vertebra column resection and reconstruction for severe kyphosis].

OBJECTIVE: To investigate the feasibility and clinical significance of posterior vertebra column resection and reconstruction in the treatment of severe kyphosis. METHODS: We retrospectively analyzed the clinical data of 12 patients with severe kyphosis who received posterior vertebra column resection and reconstruction from January 2003 to July 2007. RESULTS: The mean operation time was 5.0 h (4.0 - 7.8 h) and the evaluated blood loss during operation was 1 800 ml (800-3,000 ml). No neurologic complications or post-operative infections were noted. The patients became ambulatory 8 days after operation. Before operation, 5 patients were found to have neurological deficit, including Frankel grade A in 1 patient and D in 4 patients. After operation, the grades were all recovered to Frankel E. After operation, the Cobb angle of the kyphosis was corrected to 38 degrees, with an average correction rate of 63%. CONCLUSIONS: Posterior vertebra column resection and reconstruction may be a safe and effective technique for the treatment of severe kyphosis. It can fully decompress the neurological structures, correct the kyphosis deformity, and achieve early weight-bearing. It is especially useful to avoid neurological injury.
