Percutaneous Endoscopic Interlaminar Discectomy for L5-S1 Adolescent Lumbar Disc Herniation

Özet

AIM: L5/S1 Adolescent lumbar disc herniation (ALDH) is usually ignored for its low incidence. Recently, percutaneous endoscopicprocedures have been widely used. To investigate the surgical techniques and clinical outcomes of percutaneous endoscopicinterlaminar discectomy (PEID) in the treatment of adolescent L5-S1 disc herniation (ALDH).MATERIAL and METHODS: A retrospective study was performed between May 2012 and September 2014, which included 23adolescent patients who underwent PEID for L5/S1 lumbar disc herniation. Ten females and 13 males were included, with a meanage of 15.4 years and a mean BMI of 25.1 kg/m2. The pre- and postoperative visual analogue scale (VAS), Japanese OrthopaedicAssociation (JOA), and modified MacNab scores, as well as perioperative data, were collected.RESULTS: The mean follow-up period was 19.7 months. The average operation time and hospital stay were 80.9 ± 7.3 minutes and5.8 ± 1.2 days, respectively. During the follow-up period, the VAS for back and leg pain decreased significantly, and JOA scoresgreatly increased (p<0.05). In terms of modified MacNab criteria, 86.9% of patients showed excellent or good results. After surgery,two patients complained of leg numbness, and another patient underwent a subsequent open discectomy due to recurrent discherniation.CONCLUSION: Considering specific anatomical peculiarities and expectation for rapid recovery, PEID is a safe and effectiveminimally invasive technique for ALDH at the L5-S1 level.
