Patient Wu, male, 42 years old, was admitted to the hospital with lumbar pain with right lower limb pain for 2 years, aggravated for 1 week. MRI of the lumbar spine showed that the L5-S1 disc was herniated, compressing the dural sac, with hyperplasia and hypertrophy of the ligamentum flavum and spinal stenosis of the corresponding segment. The patient was discharged on the third day after the operation with a lumbar girth on the second day after the operation. Three months after the postoperative review of the X-ray lumbar ortholateral position, the incision was only the size of a dollar coin Minimally invasive inferior transvertebral foraminal lumbar fusion (MIS TLIF) was performed using a paramedian incision, and the paravertebral muscles and soft tissues were bluntly separated step by step by propping up the trocar, and then a working trocar was placed for the surgical operation, thus reducing the stripping and stretching of soft tissues such as muscles, avoiding atrophy of the paravertebral muscles, and better preserving the paravertebral muscles The muscle function of the paravertebral muscles is better preserved, so that the muscle strength of the low back after surgery is little different from that of a normal person. At the same time, the operation is very traumatic, with only 50-100 ml of intraoperative bleeding, and the patient can get out of bed in 24-48 hours after the operation and be discharged in 72 hours. Economically, this procedure replaces two pedicle screws with one cortical bone screw, which is a few tenths of the cost of pedicle screws, so it can be considered as saving the cost of two pedicle screws (less than 4,000 to 5,000, more than 20,000 to 30,000). This procedure is suitable for lower back pain caused by a variety of lumbar spine diseases, and has significant advantages especially in the treatment of lumbar disc herniation, discogenic back pain, lumbar spinal stenosis, and lumbar spinal canal stenosis.
