Objective To explore the short-term clinical efficacy of Intraspine in the treatment of single-segment lumbar disc herniation. Methods A retrospective study of 80 patients with single-segment lumbar disc herniation treated with Intraspine from August 2017 to March 2019 in our hospital. The average age is 67.3±5.1 years. The operation method was simple window decompression, nucleus pulposus removal, and Intraspine insertion between spinous processes. The operation time, intraoperative blood loss and postoperative complications were recorded. At the same time, the Oswestry disability index (Oswestry disability index, ODI) and visual analogue score (VAS) were used to evaluate the clinical efficacy. Take the X-rays of the lateral position of the lumbar spine and the X-rays of the hyperextension and flexion positions. Measure and record the height of the intervertebral foramen before, 3 months, 1 year, and the last follow-up of the Intraspine segment.

Results The group was followed up for 12-24 months, with an average of 15.6±5.0 months. The average operation time of single-segment Intraspine was 55.0±12.4 minutes, and the average bleeding volume was 80±12 ml. One case of wound infection after intratraspine, and one case was repaired one year after operation. The VAS and ODI scores of low back pain and leg pain at the last postoperative follow-up were significantly different from those before the operation (P<0.05). The height of the intervertebral foramina and the height of the posterior edge of the vertebral body were greater than that of the preoperative 3 months after Intraspine implantation, and the difference was statistically significant (P<0.05). Compared with pre-operation, the difference was statistically significant (P<0.05). Conclusion Intraspine Interlaminar dynamic stabilization system for single-segment lumbar disc herniation is satisfactory in short- and medium-term follow-up. The intraforaminal height of the Intraspine segment and the height of the posterior vertebral body can be significantly improved in the short term.
