The study evaluates the prone transpsoas (PTP) approach for lateral lumbar interbody fusion, showing improved lumbar lordosis, reduced complications, and enhanced patient-reported outcomes. Conducted on 106 patients, the approach minimized operative time and demonstrated safety and efficacy in lumbar fusion.
Clinical Research Summary
• Study Focus: Prone transpsoas lateral lumbar interbody fusion (PTP) for lumbar fusion.
• Study Design: Retrospective observational study of 106 patients, single-surgeon series.
• Patient Demographics: Mean age 66 years, mean BMI 29.3, follow-up 13 months.
• Surgical Technique: Prone positioning, single-position access to anterior/posterior lumbar spine.
• Common Levels: The most common level treated was L4-5.
• Outcomes: Improved lumbar lordosis, reduced pelvic tilt, and decreased PI-LL mismatch.
• Complications: Minimal, with transient hip flexor weakness in 0.9% of patients.
• Pain Scores: VAS pain scores improved from 6 to 5 postoperatively.
• Surgical Indications: Degenerative scoliosis, spondylolisthesis, disk disease, adjacent segment disease, pseudoarthrosis.
• Adverse Events: No bowel or major vessel injuries were reported.
• Radiographic Results: Significant improvement in lumbar lordosis and pelvic parameters.
• Limitations: Single-surgeon study, short follow-up, retrospective data collection.
• Conclusion: PTP approach is safe and effective for lumbar fusion with minimal complications.
