Robotic Sciatic Nerve Decompression
Beyond the spine — treating sciatic pain at its true source, deep in the pelvis.
What is intrapelvic sciatic nerve entrapment? The sciatic nerve forms from the lumbosacral plexus and exits the pelvis through the greater sciatic foramen. Inside the pelvis it is vulnerable to inflammatory adhesions, fibrotic entrapment, endometriotic infiltration, and compression from surrounding ligaments and muscles. This intrapelvic pathology is frequently overlooked — yet it is a central driver of chronic “sciatica” that doesn’t respond to spine care.
Symptoms – Deep buttock pain • posterior thigh or radiating leg pain – Burning, sharp, or electric-type pain – Pain worsened by sitting or prolonged standing – Pelvic pain or pressure; overlap with pudendal symptoms – Symptoms persisting despite normal spine imaging
How ESSI treats it — A robotic intrapelvic approach gives direct access to the sciatic nerve at its origin and along its pelvic course: safe entry into the retroperitoneal space, precise identification of the lumbosacral plexus, access to the greater sciatic foramen, and targeted decompression under magnified visualization. Adjacent nerves that commonly contribute — the posterior femoral cutaneous, perforating cutaneous, pudendal, and gluteal nerves — are evaluated and treated in the same procedure. Benign tumors of the region (schwannomas, endometriomas) can be removed through the same minimally invasive access, avoiding large gluteal incisions.
Recovery — Gradual improvement over weeks to months; less postoperative pain and faster recovery than open approaches.
You may be a candidate if you have: chronic buttock or posterior thigh pain • sciatic-type pain without a clear spinal cause • failed conservative treatment • known or suspected pelvic endometriosis • ongoing neuropathic pain after pelvic surgery.
