Summary
A new localization technique using lead markers and imaging (X-ray, fluoroscopy, CT) improves collagenase injection for lumbar disc herniation treatment. This method enhances accuracy and effectiveness, leading to better patient outcomes in lumbar disc chemonucleolysis.
Area of Science:
- Minimally Invasive Spine Surgery
- Interventional Radiology
- Biochemical Therapies
Context:
- Lumbar disc herniation is a common cause of low back pain.
- Current collagenase injection techniques require precise needle placement.
- Accurate localization is crucial for effective and safe treatment.
Purpose:
- To develop and evaluate a more reliable and effective localization method for collagenase injection via the lateral approach.
- To improve the precision of targeting the affected disc space for chemonucleolysis.
Summary:
- A novel localization technique involves marking the tender intervertebral space with a lead marker before imaging (X-ray, chest fluoroscopy, CT) for guidance.
- This combined approach was used for collagenase injection in lumbar disc chemonucleolysis.
- The new method demonstrated significantly higher satisfactory results (88.3%) and overall improvement rates (95.9%).
Impact:
- The lead marker and imaging-guided localization method proved to be accurate, safe, economical, and effective.
- This technique offers a superior approach for collagenase delivery in treating lumbar disc herniation.
- Improved localization enhances treatment efficacy and patient outcomes in lumbar disc chemonucleolysis.
