Abstract
Objective To study the clinical efficacy of combined DEVEX-cage and pedicle screw fixation for lumbar degenerative instability. Methods Twenty-three patients with lumbar degenerative instability(10 males, 13 females) at the age of 39-68 years(mean 46.6 years) were treated with combined DEVEX-cage and pedicle screw fixation from November 2007 to December 2009. Preoperative lumbar dynamic X-ray showed lumbar degenerative instability at L3-4 in 1 patient, at L4-5 in 11 patients, at L5-Sl in 8 patients, and at L4-5/L5-S1 in 3 patients, respectively. Results The operation time was 1.5-2.3h(mean 1.8h). The intra-operation blood loss was 150-260ml(mean 180.7ml). No injury of dural matter, cerebrospinal fluid leakage, and nerve system occurred. The patients were followed up for 13 months -4 years(mean 3.2 years). The ODI score was 41.37 ± 3.68 before operation, 1125 ± 221 one week after operation, 9.98 ± 2.08 three months after operation, and 9.06 ± 2.68 at the final follow-up time after operation. The mean ODI score was significantly lower 1 and 3 months after operation and at the final follow-up time after operation than before operation(P<0.01). Good bony union was achieved in 22 patients and possible bony union was achieved in 2 patients. Mild leg pain developed in 2 patients after operation, which was improved after conservative treatment. Conclusion Combined DEVEX-cage and pedicle screw fixation is a good procedure for lumbar degenerative instability with a mild injury, a high safety and a good short-term effect.关键词
