A bursa within the posterior sacroiliac joint capsule, associated with the complex synovial and fibrocartilaginous SI joint. The posterior SI joint capsule has both synovial and syndesmotic components, and bursal spaces within the capsular tissue contribute to the complex pain patterns of sacroiliac dysfunction.
Sacroiliac joint bursitis is indistinguishable from SI joint synovitis without imaging, both producing posterior iliac crest and buttock pain reproduced by FABER and FADIR tests and posterior shear tests. CT-guided or fluoroscopic sacroiliac joint injection targets the inferior synovial component of the joint. Ultrasound can identify capsular thickening and peri-articular fluid. Prolotherapy and PRP injections target the posterior capsular-ligamentous complex.
Periarticular bursal inflammation around the SI joint capsule contributing to posterior pelvic pain with sitting and stair climbing, managed by fluoroscopic SI joint injection and pelvic stabilisation exercises.
