Abstract

Abstract:

BACKGROUND: With aged trend of population in China becoming severe, the incidence of osteoporosis fracture with thoracolumbar kyphosis is increasing. Whether osteotomy is required or not still remains a controversy.

OBJECTIVE: To evaluate the clinical efficacy and improvement in sagittal vertical axis after multiple posterior lumber interbody fusion and posterolateral fusion instrumentation for patients with osteoporotic fracture with thoracolumbar kyphosis.

METHODS: Totally 90 cases of senile osteoporosis were included in the retrospective study. Operation group included 40 patients suffering osteoporosis and thoracolumbar kyphosis who underwent anti-osteoporosis treatment and multilevel posterior lumbar interbody fusion and posterolateral fusion instrumentation. Control group included 50 patients with osteoporotic without kyphosis. The Oswestry Disability Index and Visual Analogue Scale scores were compared between two groups after follow-up. Spinoplevic parameters, such as thoracic kyphosis angle, lumbar lordosis angle, sagittal vertical axis, pelvic title and pelvic incidence were compared to evaluate the improvement in the sagittal vertical axis. The quality of life was evaluated with the Japanese Osteoporosis Quality of Life Questionnaire scores.

RESULTS AND CONCLUSION: (1) The Visual Analogue Scale and Oswestry Disability Index scores in the operation group were improved significantly compared the baseline. (2) The postoperative thoracic kyphosis angle, sagittal vertical axis, and pelvic title in the operation group were significantly improved compared with the baseline. (3) The postoperative posture, figure scores, and fear and physiological scores in the operation group were significantly improved compared with the baseline, but lower than those in the control group (P < 0.05). There were no significant differences in the pain and health scores between two groups postoperatively (P > 0.05). (4) These results indicate that spinal alignment and quality of life are significantly improved after corrective spinal surgery using multilevel posterior lumber interbody fusion and posterolateral fusion for patients with osteoporosis and thoracolumbar kyphosis.
