Percutaneous Iliosacral Screw Fixation for Pelvic Ring Injury / 대한정형외과학회잡지

ABSTRACT

PURPOSE: This study evaluated the surgical outcomes of percutaneous iliosacral screw fixation for an unstable pelvic ring injury. MATERIALS AND METHODS: Twenty patients (20 cases) who were classified as having a Tile classification type B or C pelvic ring injury. Anterior fixation was added in 17 cases to maintain the stability of the anterior pelvic structre. The radiological results were compared using Slatis and Karaharju's method and the clinical results before and after surgery were compared using Moon's method between before and after surgery. RESULTS: The outcomes of the radiological evaluation were excellent in 19 cases, good in 1. The outcomes of the clinical evaluation were excellent in 7 cases, good in 12, and poor in 1. There were similar clinical and radiological results regardless of the number of screws. One patient complained of mild discomfort in the screw entry site. Nonunion developed in one case. However, there was no lloss of fixation observed. No neurological or vascular complications were encountered during the procedure. CONCLUSION: Satisfactory outcomes could be obtained without serious complications after percutaneous iliosacral screws in the unstable pelvic ring fractures. One iliosacral screw fixation provided for the stability in a pelvic ring injury in association with anterior fixation.
