Sacroiliac Joints

These joints are part of the pelvis are the most commonly known pelvic joints to cause pain. They function to dissipate physical forces that travel through the body. Generally speaking, it is anatomically low in its natural range of movement, especially when you compare it to the neighbours — the hip joints! Hence the main role of the pelvis is to produce stability and dissipate force loads. Whereas the hip joints are allowing you to move with more freedom.

The surfaces of the sacroiliac joints are initially smooth and flat, however, as you age they tend to become more rough and friction begins to settle in. This will limit movement even more. Over time the joints fuse naturally together. However there is no set date or age for when this definitively will happen in each individual.

There are many many muscles and ligaments which insert and are attached onto the sacroiliac joints – hence pure evolution just shows how important this joint is.

When things go wrong?

When the sacroiliac joint is irritated (for the various reasons we’ll come onto), the person experiencing the pain usually points straight to the area. However a referred pain can also occur to the groin, leg, hip, bum and also sometimes to the lower part of the leg/ foot which can sometimes mimic sciatica.

A lot of the time, Pain is rarely just focal in one spot. This is because pain fibres when travelling back to the spinal cord, travel up and down 2 levels before going up to the Brain. So the Brain 🧠 interprets pain with a bunch of further mixed messages, that causes the person to experience pain in other areas too, even though the main problem areas are the SI joints. This can occur alongside further peripheral (in the limbs) nerves being trapped.

You need to know that you body is a big-bag-full-of-stuff, that stuff has to go somewhere. So with postural changes and poor repetitive movements, things can get pushed and squished in certain positions. This is where they eventually become “trapped”. More commonly with sacroiliac Joint pain – Iliohypogastric and genitofemoral nerves become trapped which radiate pain into the groin and sometimes testicles too.


People experiencing this type of pain will complain of these problems in their daily life👇:

-Painful sit to standing up

-painful whilst walking up stairs

-Points to small bumps on lower back as most tender spots

-referred pain into the hip/groin/testicles/leg/lower leg and sometimes foot

-pain worsens with certain bending motions (i.e. when put socks, shoes/ trousers on in morning)

-long walks

-walking on uneven surfaces (step off curb)

Causes found in most individuals 

-Sitting more often (especially during this lockdown 🦠)

-low levels of physical activity / weekend warriors

-leg length discrepancies (in the normal population there are maximum normal leg length differences of around 20mm – this doesn’t mean that this is the problem)

-tight / unstretched muscles

-Stressful periods in life  – WIDE variety!! (This is one of the most common things to set it off)
