Transforaminal percutaneous endoscopic lumbar discectomy ( TF-PELD ) is a minimally invasive procedure, which has developed very fast recently. The appearance of Yeung Endoscopy Spine System ( YESS ) marked the maturation of TF-PELD. The YESS consists of a video system and a rigid endoscope including optical fiber lighting, wide-angle lens, some irrigation channels and a working channel. Inclusive lumbar disc herniation can be treated, but it is inadaptable for herniated lumber disc prolapsed in the canal. The cross-sectional area of the intervertebral foramen will be expanded by using ransforaminal Endoscopic Spine System ( TESSYS ), so as to put the working tube into the canal. The puncture point is moved outside and the working tube will be put into the canal in the “far-lateral technique” invented by Ruetten et al. The deficiency of YESS is offset by the 2 techniques stated above, and the operation indications of TF-PELD are extended. In recent 20 years, the side injuries have been constantly reduced and as good clinical results as in traditional decompression procedures have been achieved. TF-PELD will hold a bright prospect.
