[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.
