Anatomical considerations of the iliac crest on percutaneous endoscopic discectomy using a transforaminal approach

Percutaneous endoscopic discectomy (PED) is a minimally invasive procedure for the surgical treatment of lumbar disc herniation (LDH). It can be performed under local anesthesia and requires a skin incision of only 8 mm, with minimal disruption of the spinal structures including ligaments and muscles. However, performing PED with a transforaminal approach (TF-PED) for the lower lumbar spine is associated with some anatomical problems such as interference from the iliac crest. This study sought to assess the operability of TF-PED for the lower lumbar spine.
