摘      要：Purpose: Combined anterior and posterior ring (APR) fixation is classically performed in Tile B2 and C1 injuries to achieve superior biomechanical ***,the posterior ring (PR) is the main weight bearing portion that is responsible for weight transmission from the upper parts of the body to the lower limbs through the sacrum and the linea *** is hypothesized that isolated PR fixation can achieve comparable radiological and clinical outcomes to APR ***,we conducted this study to compare the two fixation principles in managing Tile B2 and C1 ***: Our study included 20 patients with Tile B2 injuries and 20 patients with Tile C1 *** study was a randomized control single-blinded study via computerized random numbers with a 1:1 allocation by using random block *** study was performed at a level one trauma center.A total of 40 patients with Tile B2 and C1 injuries underwent combined APR or isolated PR fixation (Group A and B,respectively).Matta & Tornetta radiological principles and Majeed pelvic scoring system were used for the assessment of primary outcomes and postoperative *** outcomes included operative time,amount of blood loss,intraoperative assessment of reduction,need of another operation,length of hospital stay,ability to weight bear postoperatively and pain control *** used studentt-test to compare the difference in means between two groups,and Chi-square test to compare proportions between two qualitative *** set the confidence interval to 95% and the margin of error accepted to 5%.So,p ≤ 0.05 was considered statistically ***: The mean follow-up duration was 18 *** operative time (mean difference 0.575 h) and the intraoperative blood loss (mean difference 97.5 mL) were lower in Group ***,despite the higher frequency of rami displacement before union in the same group,there were no significant differences in terms of radiological outc
