Diagnostic techniques for sacroiliac joint region pain

The sacroiliac joint and pain deriving from this complex region remains poorly understood in horses, although our understanding grows as the body of literature grows. A deeper understanding can be derived by borrowing from the richer array of literature on human sacroiliac joint pain. Disease processes and diagnostic challenges appear similar in both species. A highly specific and sensitive diagnostic test for this condition does not exist, so equine clinicians have to make a presumptive diagnosis based on presenting signs, findings of clinical examination, diagnostic imaging, and the response to blocking or therapeutic medication of the sacroiliac joint region. Diagnostic tests include traditional imaging modalities like nuclear scintigraphy and transrectal ultrasound, and recent advanced imaging modalities like computed tomography. Many horses with sacroiliac joint region pain have concurrent orthopaedic injury or disease highlighting the need for complete orthopaedic assessment in horses presenting with signs consistent with sacroiliac region disease.
