Abstract

Objective: To study the morphology of fracture - dislocations sacroiliac joint injuries on CT scan pelvic with three dimensional (3D) reconstruction. Subject and method: CT scan pelvic with three dimensional reconstruction images of cases dislocation SIJ, fracture – dislocation sacroiliac joint, treated at the Trauma and Orthopedics department of Cho Ray hospital (from January 2015 to June 2019). Result: Most of cases were crescent fractures and sacroiliac joint dislocation (64.3%), in which the Day III type was the highest rate (41.7%). The main displacement direction was backward, upward and outward (42.9%). There were 3 cases of anterior fractures – dislocation sacroiliac joint (looked type). Most of cases combined with other injuries as ischiopubic rami fractures, pelvis rami fractures (35/48 patients). 8/48 patients were bilateral fracture - dislocations sacroiliac joint. Conclusion: This study provides some patterns of fracture - dislocations sacroiliac joint injuries, that were very helpful in the diagnosis, classification and choosing treatment methods.
