Summary
Minimally invasive percutaneous nucleotomy offers alternatives to open spinal surgery for lumbar disc prolapses. However, these procedures require strict patient selection and are best suited for a limited number of cases compared to endoscopic or microsurgical methods.
Area of Science:
- Neurosurgery
- Minimally Invasive Procedures
- Spinal Surgery
Context:
- Open spinal surgery, particularly for post-discotomy syndrome, has driven the development of less invasive techniques.
- Percutaneous nucleotomy encompasses various intradiscal methods like discography and chemonucleolysis.
- Since the 1970s, diverse percutaneous nucleotomy techniques have emerged, including mechanical, automated, laser, and endoscopic approaches.
Purpose:
- To review the development and clinical outcomes of percutaneous nucleotomy for lumbar disc prolapses.
- To critically assess the scientific rigor and success rates of different intradiscal therapy studies.
- To define the appropriate indications and limitations of percutaneous nucleotomy in spinal surgery.
Summary:
- Clinical results for percutaneous nucleotomy vary widely (30% to nearly 100% good/very good outcomes).
- Limited prospective randomized studies exist, with many studies being retrospective and lacking rigorous scientific design.
- Percutaneous nucleotomy is effective only for select lumbar disc disorder cases meeting strict criteria.
Impact:
- Highlights the need for more high-quality research to validate the efficacy of percutaneous nucleotomy.
- Emphasizes that percutaneous nucleotomy should be reserved for a select patient group.
- Suggests that endoscopic and microsurgical methods may offer broader applicability than percutaneous nucleotomy for lumbar disc disorders.
