Abstract:Objective To investigate the clinical efficacy of targeted puncture technique in percutaneous transforaminalendoscopic discectomy (PTED) for Adolescent Lumbar Disc Herniation (ALDH).Methods A retrospective study was performed between Jun 2014 and September 2017,which included 30 adolescent patients who underwent PETD for lumbar disc herniation.2 females and 28 males were included,with a meanage of (18.50±2.13)years and a mean BMI of (22.04±3.71)kg/m2.The pre-andpostoperative visual analogue scale (VAS),Oswestry disability index (ODI),and modified MacNab scores,as well as perioperative data,were collected.Results The mean follow-up period was (25.63±14.14)months.The average operation time and hospital stay were (118.23±31.57)minutes and (6.13±2.03)days.Besides,the average bleeding were (8.30±6.17)mL.During the follow-up period,the VAS for back and leg pain decreased significantly,and ODI scoresgreatly increased (P<0.05).In terms of modified MacNab criteria,86.87% of patients showed excellent or good results.After surgery,one patients complained of leg numbnessand underwent a second surgery.Conclusion The targeted puncture technique percutaneous transforaminalendoscopic discectomy is a safe and effectiveminimally invasive technique for ALDH.
