The posterior ring was supported with an iliac lumbar double rod fixation and the anterior ring with an INFIX fixation. Operation time and peri-operative bleeding were recorded. The reduction of pelvic fracture displacement was evaluated by Matta score, the post-operative results were evaluated according to Majeed score, and the complications were recorded.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Twelve males and five females, aged 21\u201371\u00a0years (mean 40.1\u2009\u00b1\u20093.8\u00a0years) were followed up for three to\u00a012\u00a0months, (median 6.7\u00a0months).

Operation time was 90\u2013160\u00a0minutes (mean 112.9\u2009\u00b1\u200916.8\u00a0minutes), bleeding was 80\u2013150\u00a0mL (mean 105.9\u2009\u00b1\u200920.6\u00a0mL). X-ray three to five\u00a0\u00a0days after operation was evaluated by Matta score as excellent in 15 and good in two cases. Majeed score at last follow-up was 85\u201398 points, excellent in 17 cases.
