Unilateral Biportal Endoscopy Discectomy for High Grade Migrated Lumbar Disk Herniation with a Homemade Guider

Abstract

Percutaneous endoscopic discectomy treating high-migration disc herniation is still technical challenging. Unilateral biportal endoscopic discectomy is a potential surgical method for migrated herniation discectomy. Although UBE discectomy is more minimally invasive compared with the open surgery, the dissection of soft tissue during surgical exposure has received increasing research attention. To reduce the damage of paravertebral muscle, we introduced a homemade guider assisting UBE discectomy of high-migrated upper lumbar disc herniation and reported the related clinical outcomes. The use of self-designed guidelines for UBE can quickly and accurately establish the surgical field, simplify the operation process and reduce paravertebral muscle damage.
