Summary
A new percutaneous sequestrectomy technique using CT, fluoroscopy, and microendoscopy effectively treats herniated discs with free fragments. This minimally invasive approach offers an effective outpatient option for chronic back pain relief.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
- Spinal Endoscopy
Background:
- Percutaneous nucleotomy is limited to herniated discs without free fragments.
- Existing techniques for free fragments are often invasive or lack precise guidance.
- There is a need for advanced techniques to address free disc fragments and scar tissue.
Purpose of the Study:
- To describe a novel technique for percutaneous sequestrectomy using combined imaging guidance.
- To evaluate the safety and efficacy of this technique in patients with chronic back pain due to free disc fragments.
Main Methods:
- A new percutaneous sequestrectomy technique was developed.
- Spinal endoscopy was performed under CT and fluoroscopic guidance.
- The technique utilized CT-scanning, fluoroscopy, microendoscopy, nucleotomes, lasers, and micro-instruments.
Main Results:
- The technique was performed on 20 patients, with 17 treated as outpatients.
- No major complications were reported in any patient.
- The method demonstrated effectiveness in treating small free fragments and scar tissue.
Conclusions:
- The described technique offers an effective and safe outpatient treatment for specific spinal conditions.
- Combined CT, fluoroscopy, and microendoscopy provide precise guidance for percutaneous spinal procedures.
- This approach expands treatment options for herniated discs with free fragments.
