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.
Level Of Evidence:
Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
