What Is a Sacroiliac Sprain?
A sacroiliac sprain is a sprain in the sacroiliac joint, which connects the spine and pelvis. This joint is a critical part of the body, providing support and stability which allows people to walk upright. The joint is surrounded by a number of tough ligaments and muscles which are designed to stabilize it. When these muscles are strained, a patient can develop a sacroiliac sprain. Pregnancy can sometimes lead to a sacroiliac sprain, because pregnant women secrete a hormone which relaxes the bones and ligaments of the pelvis in preparation for labor and delivery. Strains can also be caused by heavy lifting. If people lift improperly, without adequate bracing and support, they can strain ligaments in a variety of parts of the body, including the sacroiliac joint. Stress from poor posture and strenuous physical exercise can also lead to a sacroiliac sprain.
