Abstract

PURPOSE
To evaluate the effectiveness and clinical outcomes of surgical fixation of a sacroiliac joint complex in unstable pelvic ring injuries.
MATERIALS AND METHODS
We selected sixteen cases in our hospital from 2006 to 2010 that underwent surgical fixation of the sacroiliac joint complex and had unstable pelvis ring injuries corresponding to B and C of Tile classification. Plate fixation through an intra-pelvic anterior approach was performed for 9 cases, tension band plate fixation for 2 cases, iliosacral screw fixation for 4 cases, and spino-pelvic fixation through extra-pelvic posterior approach for 1 case. Radiological and clinical evaluations were implemented to determine the results of treatment.
RESULTS
Bone union was observed in all patients. For radiological evaluation using the Matta and Saucedo criteria, 15 cases were above the nearly-anatomic reduction. Out of 10 cases that performed rotational displacement analysis, 9 cases were above fair. All cases had above moderate clinical results as well.
CONCLUSION
For unstable pelvic ring injuries, the satisfactory radiological and clinical results have been obtained through the anatomical reduction of the sacroiliac joint complex and firm internal fixation. And from the evaluation of fracture types, the Type C fracture and vertical shear type fractures showed relatively poor results.
