Percutaneous endoscopic lumbar herniectomy for high-grade down-migrated L4-L5 disc through an L5-S1 interlaminar approach: a technical note.
L4-L5 disc herniations can be treated with percutaneous endoscopic lumbar discectomy (PELD) using a transforaminal posterolateral approach. Although PELD has some distinct advantages over conventional open discectomy, inadequate decompression is a major cause of failure of the procedure, especially with high-grade migrations. The objective of this technical note is to present a new surgical approach for treating high-grade, down-migrated, L4-L5 disc herniations through an L5-S1 interlaminar endoscopic approach. ⋯ This technical note presents a new technique for treating high-grade, down-migrated, L4-L5 disc herniations with PELD using an L5-S1 interlaminar approach.
