Abstract
Purpose
Additional CT imaging for fragility fractures of the pelvis (FFP) has a high detection rate for concomitant posterior ring fractures (cPRFs). However, the clinical value of routine additional CT imaging is unknown. This study aimed to determine the additional clinical value of routine CT imaging by changes in treatment policy and to establish the predictive value of pain localized around the sacroiliac joint (SIJ) for cPRFs.
Methods
A prospective cohort study was conducted in a single teaching hospital in the Netherlands between November 2019 and November 2020. Patients were included if they were ≥ 65 years and had a (suspected) FFP on the pelvic radiograph. All patients underwent additional CT imaging. Changes in treatment policies ((possible) surgery, restrictive weight-bearing, hospital admission and outpatient follow-up) after CT imaging were registered.
Results
Fifty-one patients (44 female) were included with a mean age of 80.6 years. Routine CT imaging revealed an additional cPRF in 27 patients (53%). A change in treatment occurred in 29 patients (57%), of which 7 (12%) were managed either surgical or with restrictive weight-bearing. The presence of pain around the SIJ had a sensitivity of 89% and specificity of 61% for detecting a cPRF.
Conclusion
Routine additional CT imaging has few direct therapeutic consequences with regards to surgical management or restrictive weight-bearing. These findings may be altered when considering a lower threshold for surgical intervention. The presence of pain around the SIJ was highly predictive for a clinically relevant cPRF.
