Abstract:
To characterize the success and complications of percutaneous posterior pelvic fixation in the treatment of displaced spinopelvic dissociation patterns. Design: Retrospective cohort study. Setting: Three Level I trauma centers. Patients: 53 patients with displaced spinopelvic patterns were enrolled. Intervention: Percutaneous iliosacral screw fixation was used. Main outcome measures: Main outcome measures include incidence of union, fixation failure, and soft tissue complications. Results: All patients had displaced, unstable patterns with a mean preoperative kyphosis of 29.7 ± 15.4 degrees (range, 0–70). Most of the patients treated were neurologically intact (72%) or had an unknown examination at the time of fixation (15%). The median follow-up was 254 days (interquartile range, 141–531). The union rate was 98%. Radiographic and clinical follow-up demonstrated 1 case (2%) of nonunion. Two patients (4%) had radiographic evidence of screw loosening at the final follow-up, both of whom had fixation with a single sacroiliac-style screw placed bilaterally and went on to uneventful union. Neurologic recovery occurred at an average of 195 ± 114 days (range, 82–363 days). When present, long-term neurologic sequelae most commonly consisted of radicular pain and paresthesias at the final follow-up (n = 3, 6%). Conclusions: Percutaneous posterior pelvic fixation of select displaced spinopelvic dissociation seems to be safe with a low complication rate and reliable union. In a cohort of displaced fractures that were fixed in situ, we found a 2% rate of fixation failure/nonunion. Although rare, radicular pain and paresthesias were the most common long-term neurologic sequela. Level of Evidence: Therapeutic Level IV.
