Microendoscopic discectomy (MED) is a feasible outpatient procedure for treating far-lateral lumbar disc herniation, offering excellent outcomes with minimal complications. This minimally invasive technique provides direct visualization and removal of herniated discs, improving radicular pain and neurological deficits.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Far-lateral disc herniations can cause significant radicular pain and neurological deficits.
- Traditional open surgical techniques may involve larger incisions and potential complications.
- Microendoscopic discectomy (MED) offers a minimally invasive alternative for lumbar disc herniation.
Purpose of the Study:
- To evaluate the feasibility and outcomes of performing far-lateral lumbar discectomy using the microendoscopic discectomy (MED) technique.
- To assess the efficacy of MED in treating radicular pain and neurological deficits caused by far-lateral disc herniations.
Main Methods:
- Prospective study of 11 consecutive patients with unilateral, single-level radiculopathy due to far-lateral disc herniation.
- Diagnosis confirmed by MRI and/or CT scans.
- Percutaneous discectomies performed using the MED technique under epidural anesthesia on an outpatient basis.
Main Results:
- All 11 patients showed postoperative improvement in radicular pain and neurological symptoms.
- 10 excellent and 1 good result achieved based on modified Macnab criteria.
- No residual motor deficits; minor residual sensory changes in 4 patients.
- No surgical complications reported.
Conclusions:
- Microendoscopic discectomy (MED) is a safe and effective technique for treating far-lateral lumbar disc herniations.
- MED allows for direct visualization and removal of herniated discs through a small incision.
- Outpatient MED reduces hospital costs and recovery time compared to open procedures.
