Abstract

Background context: 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.

Purpose: The study aimed to introduce far lateral approach of biportal arthroscopic technique using 30° arthroscopy for foraminal decompression of L5-S1.

Study design: Technical note.

Patient sample: 12 consecutive patients.

Outcome measures: The leg VAS with modified Macnab criteria was measured.

Result: The leg VAS improved from VAS 7.5 to 1.8.

Conclusion: Far lateral approach of BASS with 30° arthroscopy is an alternative method that can decompress foraminal stenosis minimally invasively.
