Abstract

Lumbar foraminal stenosis or extraforaminal stenosis is a common cause of spinal cord radiculopathy. Recently, several authors have introduced an endoscopy-based spinal surgery technique. The study aimed to introduce far lateral approach of biportal arthroscopic technique using 30° arthroscopy for foraminal decompression of L5-S1. Technical note. 12 consecutive patients. The leg VAS with modified Macnab criteria was measured. The leg VAS improved from VAS 7.5 to 1.8. Far lateral approach of BASS with 30° arthroscopy is an alternative method that can decompress foraminal stenosis minimally invasively.
