At present, due to the proposal of the concept of postoperative accelerated rehabilitation surgery, surgical treatment tends to be minimally invasive and more precise. Therefore, the existing percutaneous minimally invasive screw and screw technology slowly becomes the mainstream treatment mode of pelvic fracture. The sacroiliac joint screw is a minimally invasive screw treatment technology aiming at unstable fracture of the posterior pelvic ring, and the screw vertically passes through the sacroiliac joint from the lateral side of the ilium and enters the sacrum 1 or sacrum 2 vertebral body, thereby realizing internal fixation, having small wound, less bleeding, providing stable biomechanics and having good vertical and rotational stability.
