Research progress in the treatment of traumatic spinopelvic dissociation / 中华骨科杂志

ABSTRACT

Traumatic spinopelvic dissociation is trauma-induced complete separation of the pelvis and spine anatomy. It is characterized by longitudinal fracture lines on both sides of the sacral bone with transverse fractures, multiplane unstable fractures, more common in high-energy violent injury, more combined injuries, high incidence of sacral nerve injury, improper treatment can easily lead to fracture re-displacement, painful deformity healing, secondary nerve injury, dysfunction and other adverse consequences. The difficulty in the surgical treatment of traumatic spinopelvic dissociation lies in the reduction and fixation of fractures. Among them, it is still controversial whether the reduction method of fracture should be open reduction or closed minimally invasive reduction, the internal fixation should be simple sacroiliac screw or plate, iliolumbar fixation or triangular fixation, and whether the sacral nerve injury needs direct decompression. With the improvement of the understanding of spinopelvic dissociation injuries and clinical application of closed minimally invasive reduction technology, minimally invasive sacroiliac screws, iliolumbar fixation, and triangular fixation are increasingly used in clinical treatment, postoperative wound complications are significantly reduced, patient function prognosis is good, indirect decompression of the injured sacral nerve after fracture reduction helps to restore nerve function, but when the fracture displacement is large with a narrow sacral canal and the nerve is compressed by the fracture or free bone mass, direct decompression by laminectomy is recommended.
