Summary
The interlaminar endoscopic technique for lumbar disc herniation surgery shows better clinical outcomes and fewer complications than the transforaminal technique. Both methods are effective, but interlaminar offers superior results.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Lumbar disc herniation is a common cause of low back pain.
- Endoscopic techniques offer minimally invasive surgical options.
Purpose of the Study:
- To compare the clinical outcomes of transforaminal versus interlaminar endoscopic techniques for lumbar disc herniation surgery.
- To evaluate complication rates associated with each endoscopic approach.
Main Methods:
- A comparative study involving 55 patients with lumbar disc herniation.
- Patients underwent either transforaminal (24) or interlaminar (31) endoscopic surgery.
- Clinical outcomes assessed using Visual Analog Scale and Oswestry Disability Index preoperatively and at 1 and 12 months postoperatively.
Main Results:
- Overall good results were achieved in 89.1% of patients.
- The interlaminar technique had a complication rate of 9.6%.
- The transforaminal technique had a complication rate of 12.5%.
Conclusions:
- Both transforaminal and interlaminar endoscopic techniques are safe and effective for lumbar disc herniation.
- The interlaminar endoscopic technique demonstrated superior clinical results and lower complication rates compared to the transforaminal technique.
