Summary
Long arm pedicle screws effectively correct spondylolisthesis in degenerative lumbar spondylolisthesis (DLS) surgery, significantly improving listhesis and spinopelvic parameters like pelvic tilt and sacral slope.
Area of Science:
- Spine surgery
- Orthopedics
- Radiology
Background:
- Posterior instrumentation with long arm pedicle screws is a standard technique for spondylolisthesis reduction.
- Degenerative lumbar spondylolisthesis (DLS) presents challenges in achieving optimal spinal alignment and spinopelvic balance.
Observation:
- A retrospective study evaluated patients with DLS undergoing reduction surgery using long arm pedicle screws.
- Preoperative and postoperative radiological parameters, including listhesis and spinopelvic measurements, were analyzed.
Findings:
- The study demonstrated a statistically significant correction of listhesis by 85.85% post-surgery.
- Significant improvements were observed in spinopelvic parameters, with a decrease in pelvic tilt and an increase in sacral slope.
Implications:
- Long arm pedicle screw reduction surgery is effective for DLS, achieving substantial listhesis correction.
- This technique aids in restoring spinopelvic parameters, contributing to improved patient outcomes.
