Effect of Modified Assisted Reduction and Internal Fixation System on Chronic Pain and Long-term Prognosis After Isthmic Spondylolisthesis Surgery: A Randomized Controlled Study
Randomized controlled study investigates modified internal fixation impact on chronic pain and prognosis in patients with spondylolisthesis, suggesting improved outcomes.
Key Points
This research aims to evaluate the effectiveness of a modified assisted reduction and internal fixation system in relieving chronic pain after isthmic spondylolisthesis surgery.
58 patients with isthmic spondylolisthesis underwent randomized division into two groups: observation and control.
The observation group used a modified internal fixation system; the control group utilized traditional methods.
Postoperative rehabilitation and evaluations were performed, measuring pain and disability using specific scales over 12 months.
Radiological measurements for intervertebral height and spondylolisthesis degree were recorded.
No significant difference in visual analog scale scores for low back pain or radicular symptoms between groups.
The observation group showed better radiological outcomes, with significant differences in intervertebral height and spondylolisthesis degree after 12 months.
Fusion rates were 85.7% for the observation group and 76.7% for the control group, showing no significant difference.
The observation group reported no implant-related complications, while the control group experienced minor issues with pedicle screws.
