Goldthwaite and Osgood indicated the sacro-iliac joint  (SIJ) as a probable cause of low backache in 1905, but it was generally disregarded since Mixter and Barr identified the disc between the vertebrae as the primary culprit in back discomfort in 1934. There is proof that this joint's malfunction could cause discomfort to travel down the identical path as the sciatic nerve, much like a bulging lumbar spinal disc (1). The Sacroiliac (SI) joint (SIJ) dysfunction pain usually occurs at the region of base of spine at the affected side (low back) and Gluteal/Buttock area that may radiate to proximal thigh till knee.
