Sacroiliac Joint Sprain / Piriformis Syndrome

“An incredibly common, and often overlooked reason for pain…”

What is a sacroiliac joint?

Your pelvis is made of three bones, two big hip bones (ilia) and one sacrum. These bones are joined by three joints, one at the front (pubic symphysis) and two sacroiliac joints at the back. The sacroiliac joints are large, weight baring joints that help transmit forces form the lower body to the upper body. There are no muscles that directly influence the sacroiliac joints, instead ligaments and the shape of the joint form the stability of the joint, due to this, these joints are often predisposed to recurrent injury.

What does sacroiliac pain feel like?

Symptoms of sacroiliac joint pain are relatively easy to spot. Research tells us that 94% of patients with SI pain will feel the pain in their buttocks, 14% in their groin, 72% in their lower back (Curtis.W 2001). The pain is often dull and aching, it is often felt to one side of the spine and normally peaks on certain movements such as going from seated to standing and turning over in bed.

What can we do?

First the chiropractor must deduce why the sacroiliac joint is painful, sometimes this will be due to excessive movement in the joint, whereas it can also be due to not enough movement, the two causes of pain require very different treatments. Sacroiliac joint syndrome can arise for acute trauma right through to chronic postural strain. Often your chiropractor will use a manipulation if the joint is tight, however if there is excessive movement a course of exercise will usually be prescribed.
