Ameliorated Full-Endoscopic Transforaminal Decompression for L5-S1 Foraminal and Extraforaminal Stenosis.

ABSTRACT:

Study design

This is a retrospective review.

Objective

To describe a modified surgical technique, full-endoscopic transforaminal decompression (FETD) in patients with L5-S1 foraminal stenosis or extraforaminal stenosis (EFS) and to detail the short-term results.

Summary of background data

Performing FETD surgery for L5-S1 FS and EFS is challenging because of high iliac crests in most cases and the difficulty in accurately differentiating between FS and EFS by images preoperatively.

Material and methods

Patients who had solitary unilateral L5-S1 FS or EFS and had undergone FETD between October 2014 and December 2017 were included. In total, 22 patients underwent FETD for L5 root compressions at the L5-S1 levels. All patients were followed up for more than 1 year
