Overview

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.
