In this brief study we provide evidence that earlier and more recent findings pertaining to the anatomy and physiology of the sacroiliac joint suggest that dysfunction in this joint could, similar to a herniated lumbar disc, produce pain along the sciatic nerve. These observations might explain some of the cases of sciatica in which no disc pathology can be found.
