Sacroiliac joint (SIJ) dysfunction due to minor subluxation of the joint can cause SIJ pain. Most patients with SIJ dysfunction or pain are treated conservatively. Long-term joint subluxation can induce inflammation in the intraarticular region. For chronic and severe SIJ conditions, various conservative therapies should be administered according to the pathophysiology of each condition. In addition, SIJ dysfunction occasionally occurs with lumbar spine or hip joint disorders.
