Lateral Transpsoas Approach for Lumbar Indirect Lateral Recess Decompression: 2-Dimensional Operative Video.

ABSTRACT

Neurogenic claudication is a common symptom of lumbar spinal stenosis; its pathophysiology is thought to be ischemia of the nerve roots secondary to compression from surrounding structures. The stenosis of the lateral recesses and neuroforamen can cause these symptoms and its surgical treatment is decompression. The placement of interbody cages that restore the disc space height may indirectly decompress the neuroforamen and alleviate the nerve impingement symptoms. In case of concomitant low-grade spondylolisthesis, interbody devices might also reduce the slippage. We present a technical surgical video of a minimally invasive lateral transpsoas fusion, relying on indirect decompression to treat a patient with neurogenic claudication secondary to grade 1 spondylolisthesis. The patient signed a written consent to publish a video, recording, photograph, image, illustration, and/or information about him.
