A Novel Foraminoplasty Technique for Posterolateral Percutaneous Transforaminal Endoscopic Lumbar Surgery

摘要

BACKGROUND: In posterolateral percutaneous transforaminal endoscopic lumbar surgery, foraminoplasty is currently performed by resecting part of the superior articular process together with surrounding soft tissues. This procedure remains technically demanding. An ideal foraminoplasty technique should be safe, easy, efficient, and controllable and should minimize X-ray exposure.
