The BacFuse System is a posterior, non-arch root fixation system for single-stage vertebral disease outside the cervical spine (Tl-Sl) in the following indications: degenerative disc disease, spinal slippage, trauma (e.g., fracture or dislocation), and/or tumor. The BacFuse System was approved by the U.S. Food and Drug Administration (FDA) in 2011 and has been successfully performed in more than 200 procedures in the United States, with no adverse events reported to the FDA. At the same time, the Middelheim Hospital (Belgium) has performed more than 100 Backfuse surgeries, and the corresponding hospitals in France and the Netherlands have also performed nearly 1000 cases of this procedure. The procedure has the following advantages: ①minimally invasive; can be applied to patients with osteoporosis; postoperative revision of conventional open pedicle screw surgery. (2) Lateral insertion into the spinous process prevents damage to the posterior spinal structures, especially the supraspinous ligament; allows “stacked tile” fixation between adjacent spinous processes of less than two segments; can be used with bone graft material. ③ Wide range of application, suitable for T1-S1 degenerative disc disease, spinal slippage, trauma (such as fracture or dislocation)
