Spine Surgery
Endoscopic Lumbar Decompression
Endoscopic lumbar decompression removes the disc fragment, bone spur, or thickened ligament compressing a spinal nerve through a small working channel under direct camera visualization. Most procedures are performed on an outpatient basis.
What Endoscopic Decompression Treats
Endoscopic lumbar decompression is appropriate for patients with nerve compression caused by a structural problem that has not responded to conservative treatment. Common indications include:
- Lumbar disc herniation causing leg pain or weakness
- Lumbar spinal stenosis with neurogenic claudication
- Foraminal stenosis compressing a nerve root
- Extraforaminal disc herniation
- Selected recurrent disc herniations
How the Procedure Works
Small incision
Typically less than 1 cm, through which a working cannula is placed.
Endoscope placement
A small camera provides direct visualization of the operative field.
Decompression
The herniated disc fragment, bone spur, or thickened ligament compressing the nerve is removed under direct vision.
Closure
The incision is closed with a single suture or skin closure strip. Most patients go home the same day.
Patient Selection
Not every patient with back or leg pain is a candidate for endoscopic decompression. Surgery is recommended when imaging confirms a structural problem that correlates with the patient's symptoms, and when conservative treatment has been given a reasonable trial without adequate relief.
The evaluation includes a thorough history, physical examination, and review of imaging. Dr. Blythe will explain whether endoscopic decompression is appropriate for your specific condition, what the procedure involves, and what outcomes are realistic.
Frequently Asked Questions
- Am I a candidate for endoscopic lumbar decompression?
- Candidacy depends on your specific diagnosis, imaging findings, and response to conservative treatment. Endoscopic decompression is most appropriate for patients with a discrete compressive lesion — such as a disc herniation or foraminal stenosis — causing nerve root symptoms. Patients with significant instability, deformity, or multilevel disease may require a different approach. Dr. Blythe evaluates each patient individually.
- How does endoscopic spine surgery differ from traditional open surgery?
- Traditional open lumbar surgery requires a longer incision and significant muscle retraction to expose the spine. Endoscopic surgery uses a working cannula typically less than 1 cm in diameter, with a camera providing direct visualization. This reduces disruption to surrounding muscle, blood loss, and recovery time for appropriately selected patients.
- Is endoscopic lumbar decompression an outpatient procedure?
- Yes. Most endoscopic lumbar decompression procedures are performed on an outpatient basis, meaning patients go home the same day. The procedure is performed under general or regional anesthesia at a surgical facility.
- What is the recovery time after endoscopic lumbar decompression?
- Recovery varies by the pathology treated and the individual patient. Many patients return to light activity within days to a few weeks. A structured return-to-activity plan is provided at follow-up. Full recovery and return to more demanding physical activity typically takes several weeks to a few months.
