Summary
Percutaneous nucleotomy (PN) offers successful lumbar disc herniation treatment for carefully selected patients. New criteria improve patient selection for this minimally invasive procedure.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Minimally Invasive Procedures
Background:
- Lumbar disc herniation is a common cause of low back pain.
- Percutaneous nucleotomy (PN) is a minimally invasive surgical option.
- Optimizing patient selection is crucial for successful PN outcomes.
Purpose of the Study:
- To present clinical results of a prospective series of percutaneous nucleotomy (PN) for lumbar disc herniation.
- To introduce refined patient selection criteria for PN.
Main Methods:
- Prospective study of 107 patients treated with PN (Hijikata's method) since 1983.
- Follow-up of 85 patients for over 2 years.
- Analysis of clinical findings, imaging (MRI, CT discography), and operative findings to identify factors influencing outcomes.
Main Results:
- 54 out of 85 patients (over 2-year follow-up) achieved successful results with PN.
- Identified key criteria for successful PN: age < 40, no posterior longitudinal ligament perforation, no canal stenosis, normal neural structures, significant muscle weakness (Grade 4+), and failed conservative treatment (> 6 months).
Conclusions:
- Percutaneous nucleotomy can yield successful clinical results for carefully selected lumbar disc herniation patients.
- Established new, evidence-based criteria for optimizing patient selection for PN, enhancing treatment efficacy.
