Summary

43% or so of far lateral lumbar disc herniation (FLLDH) occurred at L5/S1, however, the surgical treatment is still quite challenging. We conducted a modified PELD technique that enable us to remove the extraforaminal herniated disc at L5/S1, through the anatomical space surrounded by transverse process, facet joint and sacrum (TFS space). This study is to this technique's effect and safety in a one year follow-up.

Conditions

  • Neuralgia, Sciatic

Interventions

PROCEDURE

PELD operation

Under local anesthesia, the introduction of 20G needles could be performed with fluoroscopy. After the needle traveled through TFS space, extremely care was needed to avoid nerve root injury. Discography was recommended. The following steps were performed as usual: the needle was replaced by a guide wire; a 9 mm incision was made in the skin; a tapered cannulated dilator was inserted along the guide wire; and finally a working cannula was inserted. The remove of disc was performed carefully under endoscope. The first step was to locate the annulus fibrosis of L5/S1 disc, then by using nerve dissector and bipolar elliquence, soft tissue including fat tissue, muscle and fibers of ligaments were pushed cephalad until the blue stained herniated disc was visible and removed.
