Effect of Percutaneous Posterior Pelvic Ring Reduction and Fixation on Patient-Reported Outcomes

Objectives: The purpose of this study was to assess patient outcomes using Patient-Reported Outcomes Measurements Information System (PROMIS) scores after closed reduction and percutaneous fixation (CRPF) of the posterior pelvic ring and determine whether quality of reduction affects the outcomes. Design: This is a retrospective cohort study. Setting: The study involved a Level I trauma center. Patients: The study included 46 adult patients with operatively treated pelvic ring injuries (63% OTA/AO 61-B) who underwent CRPF between 2014 and 2018 at a single institution. Intervention: The intervention involved closed reduction and percutaneous posterior pelvic ring fixation. Main Outcome Measurements: The main outcome measurements were postoperative patient PROMIS scores, including physical function, pain interference, anxiety, and depression, and radiographic measurements of postoperative displacement and pelvic deformity. Results: After CRPF, PROMIS scores of physical function, pain interference, and anxiety were significantly improved at the time of final follow-up when compared with the first postoperative visit. The amount of malreduction or pelvic deformity did not significantly affect outcome scores; however, results were limited by small sample size. Conclusions: CRPF of posterior pelvic ring injuries results in good functional and radiographic outcomes. Degree of malreduction may not affect outcomes as much as previously believed.
