The goal of this study is to compare the sequence of fixation in Vertically Unstable Tile C1.2 and C1.3 pelvic ring injuries, as regards clinical, radiological outcomes and implant failure rates. Our hypothesis is that starting with anterior ring fixation will achieve superior results as regards easier reduction, less operation time, and finally better radiological and functional outcomes when compared with starting with posterior ring fixation.

The procedure will involve addressing the pelvic ring anteriorly with open reduction and internal fixation (ORIF) of the pubic rami and symphysis pubis by using a single 3.5 mm recon plate. The goal isto achieve anatomical reduction and stable fixation to restore the integrity of the pelvic ring. Fixation of the posterior ring will be achieved using a single sacroiliac screw in S1. The goal of posterior fixation is to achieve stability and alignment of the posterior pelvic structures.
the procedure will involve fixation of the posterior ring which will be achieved by using a single sacroiliac screw in S1. Then open reduction and internal fixation (ORIF) of the pubic rami and symphysis pubis by using a single 3.5 mm recon plate.

RECRUITINGRadiological outcome scores
Patients will be followed up at two weeks, six weeks, three months, six months and one year postoperatively. Matta \& Tornetta radiological principles will be used to assess the radiological and clinical outcomes via plain X-ray of pelvis showing both hips through anteroposterior, inlet and outlet views. Evaluation of five criteria on X-ray films postoperatively: residual posterior displacement, vertical displacement, pubic symphyseal translation, sagittal rotation and gapping of the sacroiliac joint. According to the grading of Matta \& Tornetta principles, results will be as follows; excellent (\< 4 mm), good (4 - 10 mm), fair (10- 20 mm), and poor (\> 20 mm).
Time frame: 12 months
Clinical outcome score
Clinical outcome assessment at final follow up using Majeed pelvic score. Five factors are assessed and scored: pain, standing, sitting, sexual intercourse and work performance. The total score is then given a clinical grade as excellent, good, fair or poor.
Time frame: 12 months
Operative time in minutes.
Operative time will be recorded in each group
Time frame: 3 hours
Implant failure rate
Implant failure if any, will be recorded during follow up.
Time frame: 12 months
