Radiographic evaluation of reactive osteitis in traumatic injury of sacroiliac joints.

Clin Imaging 2021 Apr 29;76:175-179. Epub 2021 Apr 29.

Departments of Radiology and Orthopaedic Surgery and Rehabilitation, Loyola University Chicago Stritch School of Medicine, 2160 S 1st Ave, Maywood, IL 60153, United States of America. Electronic address:

Objectives: After traumatic Sacroiliac (SI) joint injury, follow up radiographic imaging can demonstrate subchondral bone resorption resembling inflammatory sacroiliitis. No studies have described the incidence of marginal SI post-traumatic osteitis, the probable temporal relationship to the initial traumatic injury, or the possible effect of unilateral hardware fixation on the contralateral SI joint.

Methods: A Level 1 trauma center imaging database was queried to identify patients with pelvic bony trauma between 2005 and 2017 with CT baseline preserved SI cortication and unilateral/bilateral traumatic SI diastasis. Read More
