Sacroiliac joint dysfunction
medical condition
The term sacroiliac joint dysfunction refers to abnormal motion in the sacroiliac joint, either too much motion or too little motion, that causes pain in this region.
Signs and symptoms
Common symptoms include lower back pain, buttocks pain, sciatic leg pain, groin pain, hip pain (for explanation of leg, groin, and hip pain, see referred pain), urinary frequency, and "transient numbness, prickling, or tingling". Pain can range from dull aching to sharp and stabbing and increases with physical activity. Symptoms also worsen with prolonged or sustained positions (i.e., sitting, standing, lying). Bending forward, stair climbing, hill climbing, and rising from a seated position can also provoke pain. Pain can increase during menstruation in women. People with severe and disabling sacroiliac joint dysfunction can develop insomnia and depression. Sacral rotation can be transmitted distally down the kinematic chain and, if left untreated over a long period of time, may lead to severe Achilles tendinitis.
Causes
Hypermobility
Sacroiliac joint dysfunction is an outcome of either extra-articular dysfunction or from intraarticular dysfunction.
SI joint dysfunction is sometimes referred to as "sacroiliac joint instability" or "sacroiliac joint insufficiency" due to the support the once strong and taut ligaments can no longer sustain.
