Surgical outcomes of full-endoscopic lumbar discectomy by transforaminal approach (FELD TF) at lumbar spine under local anesthesia for teenagers

Abstract

Introduction: With the increasing use of full-endoscopic spine surgery (FELD) in lumbar disc herniation (LDH), FELD has been introduced to the treatment of LDH in teenagers. FELD by transforaminal approach (FELD TF) can be performed under local anesthesia. Although FELD TF is good indication for LDH in teenagers because it is minimum invasive and enable patients to return to school early, surgeons may have some concern about whether teenagers can understand requests from surgeons intraoperatively or not.

Purpose: To evaluate surgical outcomes of FELD TF at lumbar spine under local anesthesia for teenagers.

Subjects and methods: We evaluated the mean operation time, perioperative complications, VAS and the improvement of VAS for teenagers who was performed FELD TF under local anesthesia from April 2014 to March 2021.

Results: 14 male and 6 female were included in this study. The mean age was 16.9 years. The mean operation time was 34.5 minutes. Intraoperative complication was nothing, but a discal cyst was occurred.

Preoperative VAS in LBP, leg pain and numbness was 69.8, 77.1 and 62.1. Postoperative VAS was 19, 13.8 and 11.5. The improvement of VAS was 72.8, 82.1 and 81.5%.

Conclusions: FELD TF at lumbar spine under local anesthesia for teenagers was useful and safe procedure.
