Abstract:
Unstable sacral fracture is usually caused by high-energy trauma. Unstable sacral fracture often results in damage to the mechano-conductive structures of the spine and pelvis and thereby affects walking dysfunction. Treatment of sacral fracture has been a challenge due to the complex local anatomy, unique biomechanics and poor bone quality of the sacrum. The screw-rod fixation system has always played an important role in the treatment of variant sacral fracture and more severe sacral fracture. With the introduction of new technology, the screw-rod fixation system has evolved into a variety of structural types. According to whether the fixation range extends to the spine, it can be divided into two categories including spine-pelvic stabilization techniques and pelvic stabilization techniques. The authors review the progress of the screw-rod fixation system in the treatment of sacral fracture from aspects of biomechanical properties and clinical efficacy, so as to provide a reference for the selection of clinical internal fixation.
