    Abstract:
    OBJECTIVE: To investigate the efficacy and safety of total spine endoscopy in the treatment of lumbar disc herniation combined with posterior apophyseal ring separation. METHODS: From January 2015 to January 2018, a total of 21 patients with lumbar disc herniation complicated with posterior apophyseal ring separation were treated with total spine endoscopy via interlamina approach. There were 17 males and 4 females. The age ranged from 18 to 48 years old and the median age was 27 years old. All were single segment unilateral disc herniation, interlaminar approach was adopted, and the herniated disc was removed unilaterally at the symptomatic side under the microscope, and all or part of the broken bonewas removed. RESULTS: There were no complications such as incision infection, intervertebral space infection, intestinal injury, dural injury and cerebrospinal fluid leakage. The operation time ranged from 32 to 92 minutes and the median time was 57 minutes. Postoperative imaging examination showed that 2 patients had complete resection of osteotomy of posterior edge of vertebral body, 16 patients had partially resection and 3 patients had no resection. All intervertebral discs were completely removed. All 21 patients were followed up, and the duration ranged from 12 to 36 months, with a median of 15 months. The VAS of lumbago was 7.10±1.20 before surgery, 3.46±0.23 on the 3rd day after surgery, 2.36±0.19 on the 6th month after surgery; and the VAS of leg pain was 8.80±0.55 before surgery, 3.54±0.28 on the 3rd day after surgery, and 2.59±0.26 on the 6th month after surgery. The Oswestry Disability Index score was (69.71±9.37)% before surgery, (32.19±6.95)% on the 6th month after surgery, and (20.95± 6.16)% at the latest follow up. Onthe 1st year after operation, 16 patients got an excellent result, 4 good and 1 fair according to Macnab evaluation system. CONCLUSION: Total spine endoscopy via interlaminal approach can be used as an option in the treatment of lumbar disc herniation combined with vertebral posterior margin dissociation, which can reduce trauma and injury to the lumbar dorsal muscle and achieve similar decompression effect as open surgery. The long term efficacy needs to be further proved by prospective randomized controlled studies with larger sample size.
