Summary
Unilateral biportal endoscopic spine surgery (UBESS) effectively treated lumbar foraminal stenosis in an elderly patient. This minimally invasive approach preserved spine function and yielded excellent clinical outcomes with no muscle damage.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
- Spinal Endoscopy
Background:
- Minimally invasive spine surgery (MISS) techniques reduce tissue injury compared to open surgery.
- Endoscopic discectomy has evolved for lumbar disc herniation and stenosis, preserving spine function.
- Good clinical outcomes are reported for degenerative lumbar disc disease using endoscopy.
Observation:
- A 70-year-old man presented with severe left L4-5 foraminal stenosis and neurogenic claudication.
- The patient underwent successful left-sided unilateral biportal endoscopic transforaminal decompression and discectomy.
- Postoperative recovery was uneventful with significant symptom relief and no muscle damage.
Findings:
- Unilateral biportal endoscopic spine surgery (UBESS) achieved successful decompression and discectomy at L4-5.
- Postoperative MRI confirmed adequate decompression and no muscle damage.
- The patient experienced significant relief from neurogenic claudication and paresthesias.
Implications:
- UBESS is a viable alternative for treating foraminal and paracentral disc herniations.
- This technique offers an effective option compared to uniportal endoscopy and microsurgery.
- Biportal endoscopic decompression provides excellent outcomes for lumbar stenosis and disc herniations.
