Sacroiliac (SI) Joint Dysfunction is a common cause of low back pain and can be easily missed when not evaluated for properly, leading to SI Joint Dysfunction being notoriously underdiagnosed as a common cause of low back pain.
The SI joint connects the lowest part of the spine (sacrum) to the pelvic bone (ileum). SI joints are typically very strong and provide structural support and stability with the aid of ligaments which hold the joint together. When the SI joint is irritated or injured, it may cause pain in the lower back. SI joints can become painful because of alterations in the normal motion of the joints, typically due to too much movement (hyper-mobility), or because of direct trauma such as a fall or motor vehicle accident. Abnormal or excessive motion can directly injure the joints by stretching or straining the primary SI ligaments.
Young and middle-aged women are most susceptible to this condition, but it can affect anyone at any age. Simple tasks such as sitting, bending, and standing can become a difficult and painful task. When SI joint dysfunction is severe, there can be referred pain into the hip, groin, and leg.
Treatment may include anti-inflammatory medications, ice, physical therapy, bracing for sacroiliac joint support, SI Joint steroid injection, Prolotherapy, Platelet Rich Plasma (PRP), and Bone Marrow Concentrate (BMC) Therapy.
