What Is the Sacroiliac Joint?
Sacroiliac Joint is the connection between the sacrum at the base of the spine and the ilium bones of the pelvis. The paired joints transfer forces between the upper body and legs while allowing limited movement. Ligaments support each joint, and surrounding muscles help control pelvic stability during walking, standing, and other daily activities.

Key Takeaways About Sacroiliac Joint
- Each sacroiliac joint links the sacrum with one side of the pelvis.
- Small movements help the pelvis manage forces during daily activity.
- Sacroiliac joint symptoms can resemble pain from the lower back or hip.
How Sacroiliac Joint Works
The sacroiliac joint connects the sacrum with the pelvic ilium. Its joint surfaces and strong ligaments limit motion while allowing the pelvis to adapt as you walk, change position, or carry weight. Muscles around the abdomen, lower back, hips, and pelvis support this movement.

Clinicians assess the joint through a history, movement observation, and focused physical examination. They may compare pelvic motion, tenderness, muscle control, and symptoms during selected movements. The lumbar spine and hip are also considered because discomfort in these areas can feel similar. An examination helps identify whether the sacroiliac region fits the overall pattern.
From the Advanced Injury Care Clinic team
When we assess the sacroiliac joint during prenatal chiropractic care, we consider pelvic movement, nearby muscle tension, posture, and the person’s reported symptoms. Our team also checks related areas, such as the lumbar spine and hips, so the care plan reflects the full movement pattern.
Sacroiliac Joint in Practice: A Real-World Example
During prenatal chiropractic care, a patient may report discomfort near one side of the pelvis when turning in bed or walking. The clinician examines pelvic and nearby spinal movement to determine how the sacroiliac region may contribute to that pattern.
