Operative management and radiological outcome of sacroiliac joint fractures and dislocation: A cross sectional study

Abstract

Pelvic ring fractures are the most unstable fractures because of the posterior ring disruption. Motor vehicle accidents lead to high-energy pelvic ring fractures, which leads to the sacroiliac joint disruption with complete or incomplete posterior ring disruption. Surgical correction of unstable pelvic fractures is must for better functional outcomes. This study was conducted to assess the short term functional and radiological outcome of the percutaneous sacroiliac screw fixation for sacral fractures and sacroiliac fracture dislocations based on scoring system suggested by Merle d' Aubigne' and Postel. All adult patients in the age group 15 to 70yrs presenting with sacral fractures and sacroiliac dislocations treated with percutaneous sacroiliac screw fixation were included in the study. 23 patients satisfying the inclusion criteria were included, and followed up over a period of 6 months. 47.8% of the patients required one screw during the surgery. 77% patients had good union of fractures, 18% had malunion and one patient had delayed union. There was no significant association between number of screws used and radiological outcome. There was significant association between radiological outcomes with associated injury with hip.
