Title: Effect of surgical treatment of degenerative lumbar spondylolisthesis on pelvic parameter and sagittal balance of the pelvis-spine complex in the elderly
Abstract: Objective
To analyze the effect of surgical treatment of degenerative lumbar spondylolisthesis on pelvic parameter and sagittal balance of the pelvis-spine complex in the elderly.
Methods
A retrospective analysis of degenerative lumbar spondylolisthesis in 20 cases was performed. The improvement in Visual Analogue Scale (VAS) of the waist or lower extremity pains and Oswestry disability index (ODI) for patients with low back pain, pelvic parameter and spinal sagittal balance, were assessed pre- and post-operatively.
Results
The average follow-up time was 35.7 months (24-84 months). No screw or plate broken was found in the 20 patients, with the inter-vertebral fusion rate of 100%. There were statistical differences in VAS and ODI scores of low back pain and leg pain before versus after treatment (P 0.05). The lumbar lordosis was increased post-operatively from (53.3±7.6)° to (46.6±6.8)° (P 0.05〕. The inclination of pelvis was decreased post-operatively from (10.7±2.1)° to (15.7±2.5)°. The sacral slope was increased post-operatively from (44.5±5.5)° to (48.6±6.8)°. Patients were grouped into ≥50% restoration and 0.05 for all).
Conclusions
The surgical treatment of degenerative lumbar spondylolisthesis has a good clinical effect in the elderly, that could maintain the spine global sagittal balance, recover the normal lumbar lordosis and improve the spinal pelvic parameters.
