ABSTRACT
BACKGROUND: Discectomy of distally, inferiorly migrated disc herniations below midpedicle level of the vertebral body in the lower lumbar spine is known to be very difficult by endoscopy. The purpose of this study was to introduce the technical possibility of percutaneous endoscopic lumbar discectomy using a contralateral transforaminal approach for distally migrated disc herniation.

METHODS: We reviewed 12 patients who underwent percutaneous endoscopic lumbar discectomy using the contralateral transforaminal approach for distally migrated disc herniation. Complete removal was verified through postoperative magnetic resonance imaging (MRI) follow-up in all patients. Mean follow-up was 25?months.

RESULTS: Clinical results according to MacNab criteria were excellent in ten patients and good in two. Average visual analogue scale for lower back pain and radicular pain improved from 6.8 and 8.2 preoperatively to 1.5 and 1.4, postoperatively (p?
