Percutaneous transforaminal endoscopic discectomy through different approaches for lumbar disc herniation / 中国骨伤

ABSTRACT

Compared with open surgery, percutaneous transforaminal endoscopic discectomy (PTED) for lumbar disc herniation (LDH) has advantages of minamilly invasive, little impact on stability of spine and rapid recovery. However, PTED by transforaminal approach has relatively limited indications and can not completely replace open surgery, due to different location of migrated herniated fragment, the level of pathological segment or presence of a high iliac crest. Development of new approach and ancillary equipment have become the focus and future direction of PTED. In recent years, interlaminar and transiliac approach extended the indications of PTED greatly. However, not-standard manipulation, improper selection of indications or surgical approach has been attributed to the main reason for failure in PTED surgery. In view of this, the paper summaries indications, different approaches and methods, clinical efficacy and complications of PTED.
