The use of pedicle screws in stabilizing posterior pelvic ring fractures
Purpose: In this study, the clinical, functional and radiological outcomes of the patients were evaluated using a pedicle screw/rod system technique in stabilizing the posterior pelvic ring fractures. Methods: This was a prospective study during the period of April 2013–January 2016 in the level 1 trauma center, and thirty-eight (38) patients underwent internal fixation for pelvic ring fractures using pedicle screws and rod technique. Out of these, twenty-four (24) were posterior pelvic ring fractures with or without anterior pelvic failure (6 cases with posterior pelvic fixation only, 7 cases fixed with anterior and posterior pedicle rod system technique, 11 cases fixed with posterior pedicle rod system and any sort of anterior pelvic ring fixation EF and/or symphyseal plate). The study group was comprised of 13 men and 11 women, with a mean age of 31 years (range 18–60 patients were followed up for a minimum of one year (12-17 months)). All patients were seriously injured and received a total-body CT scan at the time of emergency admission. Results Matta and Tornetta score was used to assess the radiological outcomes. There were thirty-eight cases in which the pelvic component of injury was managed operatively, the results were: 18 patients were excellent, 15 were good, and 5 had fare reductions. The Majeed score was used to evaluate the functional outcome of the patients, five factors were assessed and scored; pain, standing, sitting, sexual intercourse and work performance and the results for17 patients were excellent, 18 had good, 1 had fair and 1 had a poor functional outcome. Conclusion: Pedicle screw/rod system technique was a successful method for treating posterior pelvic ring disruption regarding the clinical and radiological outcomes. The reduction of sacral fracture was important to save satisfactory functional outcomes.
