With the development and mature application of modern minimally invasive surgical techniques, elderly osteoporotic to vertebral compression fractures are mostly treated with vertebroplasty and infusion of bone cement to achieve instant cure. Now there is a new minimally invasive technique, vertebral strut block internal fixation, specifically for vertebral compression fractures in young adults, which fully fills the blind spot in the treatment of spinal fractures in young adults. A 33-year-old Zhang fell from the 2nd floor a few days ago and was diagnosed with L2 vertebral compression fracture with 1/3 degree of compression, no neurological symptoms, good spinal canal morphology, lumbar back kyphosis, lumbar back pressure pain +, restricted movement, and inability to walk on the ground. We performed internal fixation of the vertebral body brace for Zhang, under the guidance of C-arm fluoroscopy with clear vision, the patient was placed prone under general anesthesia, small incisions of 1 cm were made on each side of the diseased spine vertebrae, special guide pins were implanted, the vertebral body was entered through the injured vertebral arch, the working channel was expanded, bone particles were implanted in the diseased vertebrae, a suitable vertebral body brace was selected, bone particles were filled in the brace, the vertebral body brace was screwed into the injured vertebrae, and the position After fitting, the brace was propped open to restore the vertebral height of the injured vertebra. The next day, the patient is up and about under the protection of the brace. This procedure has been successfully performed in more than 20 cases in our spine specialty with minimal intraoperative trauma, short bed rest, and good patient recovery. Compared to previous incisional internal fixation, the patient suffers less pain and does not have to be bed-ridden for a long time, especially when the internal fixation is removed twice, which reduces the pain and cost of surgery. After the short-term restrictive protection, the physiological dynamics of the spine can be restored after the rehabilitation exercise, and the bending activities can be carried out without any influence on the patients’ life.
