Surgical treatment of a Malgaigne fracture

INTRODUCTION: Sacral fractures are generally accompanied pelvic ring fractures. They rarely develop in isolated form. However, sacroiliac dislocation without sacral fracture is extremely rare.
METHOD: One sacroiliac dislocation without sacral fracture was operated. Lumbopelvic stabilization was applied using iliac wing plates. The case was evaluated according to demographic data and VAS, ASIA and Oswestry scales.
CONCLUSION: Considering the role of the sacrum, which transmits the load of the entire spine to pelvis, for ensuring the mechanic stability of the spine, meticulous care must be given when evaluating the patients with sacral and pelvic fractures. Very serious spinopelvic instability is present in sacroiliac dislocations even without sacral fractures. Caudal migration of the sacrum together with the cranial migration of the iliac wings can cause serious pelvic imbalance and difficulties in walking and maintaining the standing position. Aggressive stabilization and fusion are required, and these must be performed in the early period.
