Abstract
Background and Study Aim Foraminal disc herniations present the unique surgical challenge for exiting nerve root retraction and decompression. The aim of current study is to describe an innovative maneuver and evaluate its usefulness for endoscopic decompression of foraminal disc herniations. Material and Methods A retrospective review was performed including cases of foraminal disc herniations who underwent endoscopic discectomy utilizing the rotate-to-retract technique. Data on patient demographics and improvement in VAS/ODI scores were collected and analyzed statistically. Results There were ten patients (three male; seven female) in the final analysis. Seven procedures were done at the L4-L5 level, two were done at the L5-S1 level, and one was done at the L3-L4 level. The average VAS scores improved from preoperatively 7.5 to postoperatively 4.4 (p= 0.001). The mean preoperative ODI was 67.8 and improved to 26.6 postoperatively (p< 0.001). None of the cases reported any neurological or dural complication. Conclusion Foraminal disc herniations can be safely and adequately addressed endoscopically with the use of rotate-to-retract technique.
Highlights
Posterolateral endoscopic lumbar decompression (PLELD) is fast becoming the procedure of choice for surgical management of lumbar disc herniations [1,2,3,4,5,6,7]
The aim of this paper is to report an innovative maneuver, the “rotate-to-retract technique,” for safe retraction and decompression of the exiting neural structures during PLELD
Inclusion criteria included all patients who were diagnosed with lumbar radiculopathy due to foraminal disc herniations, failed conservative therapy, and underwent PLELD
Summary
Posterolateral endoscopic lumbar decompression (PLELD) is fast becoming the procedure of choice for surgical management of lumbar disc herniations [1,2,3,4,5,6,7]. Cases of foraminal disc herniation (FDH) present the unique surgical challenge for exiting nerve root retraction and decompression [8,9,10,11]. The aim of this paper is to report an innovative maneuver, the “rotate-to-retract technique,” for safe retraction and decompression of the exiting neural structures during PLELD in cases of FDH. Foraminal disc herniations present the unique surgical challenge for exiting nerve root retraction and decompression. The aim of current study is to describe an innovative maneuver and evaluate its usefulness for endoscopic decompression of foraminal disc herniations. The average VAS scores improved from preoperatively 7.5 to postoperatively 4.4 (p= 0.001). Foraminal disc herniations can be safely and adequately addressed endoscopically with the use of rotateto-retract technique
