Transforaminal Approach for L5-s Level
- 46 Downloads
The trajectory of TELD can be limited by the surrounding anatomical structure. TELD for the central-type lumbar disc herniation at the L5-s disc level is more technically demanding than TELD at the L4–L5 disc level because of the interference of the iliac crest. However, in the clinical setting, such anatomical particularities can be overcome by using a hand-down technique with the possible addition of a foraminoplasty when we perform TELD at the L5-s disc level.
