What Is the Sacroiliac Joint?
Sacroiliac Joint is the connection between the sacrum at the base of the spine and the ilium of the pelvis. Each person has a joint on both sides. These joints transfer forces between the upper body and legs while allowing limited movement during standing, walking, bending, and other weight-bearing activities.

Key Takeaways About Sacroiliac Joint
- The joint connects the sacrum with each side of the pelvis.
- Its movement is small but supports weight transfer.
- Nearby muscles, nerves, and hip structures can create similar symptoms.
How Sacroiliac Joint Works
Sacroiliac Joint function depends on the fit between the sacrum and the pelvic bones. Strong ligaments support the connection, while nearby muscles help control movement. The joint does not move through a large range. Its main mechanical role is to transfer load between the trunk and legs during activities such as walking or rising from a chair.

A clinician may examine pelvic motion, nearby muscle tension, gait, and the location of discomfort. Findings from the lumbar spine and hip also help separate sacroiliac joint concerns from problems in nearby structures. A chiropractic adjustment may address restricted joint motion as part of a broader physical assessment. The adjustment does not treat every source of pain in the pelvic region.
From the Advanced Injury Care Clinic team
When we assess the sacroiliac joint, we examine how the pelvis, lumbar spine, hips, and surrounding muscles work together. We use movement findings and symptom location to guide a chiropractic adjustment when restricted motion appears relevant. We also consider nearby structures that can produce similar complaints.
Sacroiliac Joint in Practice: A Real-World Example
A person may feel discomfort near one side of the lower back after lifting or prolonged sitting. During a chiropractic adjustment visit, we assess pelvic and lumbar movement before deciding whether the sacroiliac joint is a relevant part of the care plan.
