Sacroiliac Joint Injections
At the lower end of the spine lies the Sacrum. The Sacrum is a triangular shaped bone formed by the fusion of several smaller bones. The Sacroiliac (SI) joint sits between the Sacrum and the Ilium.
> The Sacroiliac joint has an irregular surface and has very little motion.
> The older one gets, the less motion occurs in the joint. This can create a significant amount of pain and loss of mobility.
