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 side of the pelvis has one sacroiliac joint. These joints transfer load between the upper body and legs while allowing limited movement during standing, walking, and changes in position.

Key Takeaways About Sacroiliac Joint
- The sacroiliac joint links the sacrum with the pelvic bone.
- Movement is limited but supports walking and weight transfer.
- Sacroiliac joint discomfort is not the same as hip joint pain.
How Sacroiliac Joint Works
The sacroiliac joint connects the sacrum with the ilium, which forms part of the pelvis. Strong ligaments support the joint and limit its movement. This design helps the pelvis remain stable as force moves between the spine and legs.

Clinicians consider the joint’s location, nearby tissues, movement patterns, and pain behavior during an assessment. Findings may be compared with the lumbar spine and hip joint because discomfort in these areas can feel similar. A practical assessment looks at how standing, walking, bending, or changing position affects the region.
From the Arrowhead Clinic - Lithia Springs team
When we assess the sacroiliac joint, we consider the person’s symptoms, posture, pelvic movement, and nearby spinal or hip findings. Our team connects those observations with functional tasks, such as walking or changing position, so the care plan addresses the full movement pattern.
Sacroiliac Joint in Practice: A Real-World Example
A person with hip-area discomfort may feel symptoms near the back of the pelvis when standing from a chair. During a hip pain treatment visit, the assessment can consider the sacroiliac joint along with the hip and lumbar spine.
