Who Is at Risk for SI Joint Problems?

Sacroiliac pain can occur in patients with widely different history, physiology, and physical examination findings.


Women and SI Joint Pain

Women may be at increased risk for SI joint problems because of their broader pelvises and greater curvature of lumbar spine, which result in different SI joint biomechanics.

Women also have more elastin in the collagen that makes up their ligaments. Elastin is a molecule that allows increased flexibility of ligaments.

In addition, pregnancy often results in stretching of the sacroiliac ligaments. Some women have permanent changes to the SI joint ligaments as a result of pregnancy.

Many of the women who've had iFuse surgery are over 50 and have been in pain for years.

Lumbar and Hip Surgery and SI Joint Pain

SI joint pain may appear after lumbar spine surgery or hip replacements.

Lifestyle Factors and SI Joint Pain

Risk factors associated with lower back pain may include: smoking, poor physical condition, positive family history, and occupational exposure to repetitive trauma to the SI joint.5,13,41
