Lumbar disc herniation in adolescents is not uncommon in clinical practice. Some data show that its incidence accounts for about 1% of all lumbar disc herniations [1]. Its pathogenesis is relatively simple, mostly due to trauma. There is no consensus on how to choose the treatment method [4]. The authors treated 21 cases of lumbar disc herniation in adolescents with non-surgical treatment from 1994 to 1999 and observed the follow-up for 4 years, and the treatment methods and efficacy are reported as follows: Clinical data (1) General data: 15 males and 6 females among 21 cases; age 12 ~ 20 years, average 16.8 years; duration of disease 7 days to 1 year and 2 months, average 10.2 months. Occupation: 12 students, 4 athletes, 4 farmers, 1 soldier; all had clear history of trauma or sprain before onset. (2) Clinical manifestations: 15 cases of low back pain with radiating pain of one lower limb, 4 cases with bilateral radiating pain; 12 cases of obvious lumbar scoliosis; 8 cases of low back muscle tension; 19 cases of positive straight leg raising test; 9 cases of decreased thumb and back extension, 8 cases of abnormal superficial skin sensation in the dominant area; 7 cases of abnormal tendon reflex. (3) Imaging examination: X-ray plain film and CT examination of lumbar spine were performed in all cases to clarify the diagnosis, and CT showed disc herniation in the corresponding intervertebral space plane. Among them, there was 1 case of L3-4, 11 cases of L4-5 and 9 cases of L5-S1; 18 cases of lateral-posterior herniation and 3 cases of central herniation. (4) Treatment method: Lumbar traction group (group 1) computer-controlled lumbar traction bed, supine position, continuous horizontal traction, mass of 1/2 to 2/3 of the patient’s body weight, 25 min each time, 15 times as a course of treatment. Epidural injection group (group 2), using the sacral canal or lumbar epidural injection method, the injection drug is prednisolone 62.5mg or Coninectone 20mg, 2% lidocaine 2.5ml, diluted to 10-20ml with saline, once a week, 3 times for a course of treatment. Patients in this group were still given lumbar traction during the injection period in the same way as group 1. Percutaneous puncture group (group 3): operated under DSA or CT monitoring, with the patient in lateral recumbency and 6-8M from the posterior midline on the horizontal line of the diseased vertebra as the entry point. The nucleus pulposus was cut and aspirated using a domestic APD-III automatic nucleus pulposus spinner for 5-10 min, and the nucleus pulposus was cut and aspirated at about 1-4 g. The needle entry point for collagenase injection was the same as above, and after the puncture needle entered the diseased disc, 1,200 units of domestic injectable collagenase and 5 ml of saline were used to extract 1 – 2 ml of collagenase into the nucleus pulposus. -Then the needle tip was retreated to the epidural space of the intervertebral foramen on the lesion side, and 3 ml of collagenase was injected after the injection of contrast agent to confirm the location of the needle tip. (5) Results Efficacy criteria: NaKai efficacy assessment criteria were used [2]. Excellent: all the symptoms and features disappeared and the original work was resumed. Good: symptoms and signs basically disappeared, occasional back and leg pain after exertion, resumed original work. Possible: symptoms and signs improved, still had mild back and leg pain, unable to perform normal work. Poor: no improvement or aggravation of symptoms and signs, unable to perform normal work. Efficacy results: the recent efficacy (within 15 days and 30 days) of the lumbar traction group (group 1) was 42.8% and 57.1%, respectively; the epidural injection group (group 2) was 62.5% and 75.0%, respectively, and the percutaneous puncture group (group 3) was 66.6% and 83.3%, respectively
