* * The lateral branches supply the Sacrospinalis. The upper three give off cutaneous nerves which pierce the aponeurosis of the Latissimus dorsi at the lateral border of the Sacrospinalis and descend across the posterior part of the iliac crest to the skin of the buttock (Fig. 801), some of their twigs running as far as the level of the greater trochanter Introduction In the first part of the 20th century, sacroiliac joint (SI joint) syndrome was the most common diagnosis for low back pain, or lumbago. Before 1932, SI joint syndrome was a particularly popular diagnosis. It was actually called the Era of SI Joint because so many physicians felt that the SI joint was the cause of most back problems. Any pain in the low back, buttock or adjacent leg was usually referred to as SI joint syndrome. In 1932, the discovery of the herniated (or ruptured) disc led many physicians to assume that most pain in the back was the result of this new problem. Thus was born the Dynasty of the Disc, and the SI joint was somewhat forgotten. In the late 1980s, many physicians rediscovered the SI joint as a possible source of back pain. Yet, even today SI joint pain is often overlooked as a cause of low back pain. Many physicians have not been trained to consider it when diagnosing back pain and many are still reluctant to believe a joint that has so little movement can cause back pain. The symptoms of back pain from problems in the SI joint are difficult to distinguish from other types of low back pain. This document will offer you valuable information about the following: Anatomy of the Sacroiliac joint Causes of SI Joint Syndrome Symptoms Diagnosis Treatment Options Possible Complications from Surgery Anatomy The sacroiliac joint (SI joint) is one of two joints in your pelvis that connect the tailbone (the sacrum) and the large pelvic bone (the ilium).
