A case is presented in which bilateral diastasis of the sacro-iliac joints and grossly abnormal motion could be demonstrated. Sacro-iliac fusion relieved the patient of her disabling symptoms. It is theorized that destruction of these joints was an unusual but extremely early finding in rheumatoid spondylitis and may have been caused by the presence of rheumatoid granulomatous nodules.
