What is Sacroiliitis

Sacroiliitis is a painful condition at the joints of the spine and pelvis, also called sacroiliac joints. In humans, there are two sacroiliac joints on either side of the pelvis. Therefore, the pain and inflammation could happen either or both of the sacroiliac joints.

This painful condition may cause other painful sensation in the buttocks or lower back region to the ankle of the legs.

This condition usually arrives in improper sitting habits, prolonged standing, injury, infection of the pelvis, etc. However, they are hard to diagnose because it could be easily mistaken as lower back pain.

Causes of Sacroiliitis

Causes of Sacroiliitis

While talking about causes, the inflammation in sacroiliac joints could be due to many reasons. But the most common causes are:

Ankylosing Spondylitis

It is a type of inflammatory arthritis that affects the spine and hip joints. This is a progressive condition of ankylosing spondylitis where the inflammation and stiffness are common in the spine and hip joints.


They are caused by excessive use of spine and hip muscle that causes wear-and-tear in them. They are common in athletes, football players, etc. So, due to the overuse of sacroiliac joints it could generate sacroiliitis.

Trauma or Injury

Any traumatic event that leads to hip, spine, or pelvis injury could damage the sacroiliac joints. And finally, it could cause inflammation of sacroiliac joints.


During the infant development in the womb of the mother, the pelvis region becomes bigger that exerts pressure on the sacroiliac joints. And that’s the only reason why pregnant women develop sacroiliitis’s inflammation.


There are certain bacteria that can cause sacroiliac joint infection. One of the major threatening bacterial species is enterococcus. If you want to learn more about this bacterial gene, please check the link.

In addition, other infections such as UTI (Urinary Tract Infection) can also be a leading cause of sacroiliitis conditions.

Note: In very rare cases, endocarditis and intravenous (IV) drug addiction could cause sacroiliitis conditions in humans.

Symptoms of Sacroiliitis

Symptoms of Sacroiliitis

The symptoms of sacroiliitis are commonly misinterpreted as lower back pain. But after close examination and closer look it can be differentiated from other back pains. And these are the most common symptoms of this inflammation condition.

  • Pain and inflammation in the buttocks, lower back, and posterior side of one or both legs.
  • Fever due to pain which mostly mild
  • Stiffness in the hips and lower back
  • Pain in hips and feet— rare

However, if you have sacroiliitis then the following activities might dwell you in pain.

  • Prolonged sitting or standing
  • Standing on one leg— bodyweight usually on one leg
  • Frequently climbing the stairs
  • Long strides while walking and running
  • A habit of sleeping on one side.

Diagnosis for Sacroiliitis

Diagnosis for Sacroiliitis

For diagnosing the sacroiliitis, your doctor may first ask about the medical history, especially related to your previous inflammatory disorder or diseases such as diabetes, arthritis, or cancer

After a preliminary inspection, your doctor now advises some series of imaging and blood tests. 

Physical Examination

In the physical examination, a doctor might first examine any injury or bruises over the lower spine region. He/she may also check for the alignment and rotation factor of the sacroiliac joints.

After testing the movement disorder in the sacroiliac joints, doctors may apply some pressure to the spine, hips, and sacroiliac joints. Now, based on the pain distribution in these areas, the doctor may conclude whether you have sacroiliitis or not.

Note: Generally, the higher the number of paining areas higher the chance that you have sacroiliac joint inflammation. 

Blood Culture Test

These are generally useful when this inflammation is due to some bacterial growth. The blood sample usually is taken from the infected area to get more accurate results.

So, an intravenous syringe is used to remove the joints fluids for blood culture. 

Imaging Tests 

If there is a case of a traumatic injury, an x-ray would be beneficent revealing the sign of damage to the sacroiliac joints.

But if in case of inflammation due to muscles, MRI is recommended by the doctor. So, with the help of an MRI scan, a doctor can easily study the cross-sectional details of both the bone and soft tissues.

Anesthetic Injections

They are not just the diagnosis test but a temporary treatment to reduce the sacroiliac inflammation.

They are generally given to those people whose inflammation and pain is unbearable. And during the procedure, injection is employed with the guidance of a live x-ray.

Treatment For Sacroiliitis

Treatment For Sacroiliitis

There are basically two broad categories for the treatment of Sacroiliitis; one is medication and the other is surgical therapy. 

Medicational Drugs

Medications are generally employed to relieve the pain and inflammation of sacroiliac joint pain. And these are the following drugs:

Pain Relievers

Muscle Relaxants

When the cause of pain is due to overuse or damage of muscle tissue then muscle relaxant drugs or intravenous injections are helpful. Some commonly used muscle relaxants are chlorobenzene

TNF Inhibitors

When you’re suffering from ankylosing spondylitis and TNF inhibitors are used to reduce the sacroiliitis condition. Some commonly used inhibitors are Enbrel, Humira, and Remicade.

Surgical Therapy and Injection

These are the following surgical therapy and injections that are commonly used to treat sacroiliac joint inflammation, both permanently and temporarily. 

Joint Injections

Medication such as corticosteroids can be injected directly into the sacroiliac joints. They are generally injected only a few times in the year. This is because, these sedatives can weaken joints, tendons, and muscles. 

Radiofrequency Denervation

They are used to destroy any sensory parts that cause inflammation. And to destroy these muscles and tissues, radiofrequency is very useful.

Electrical Stimulation

In this case, an electrical stimulator is directly placed into the sacrum area to reduce the pain receptors to reach the brain. And if the pain receptors signal doesn’t reach the brain, you didn’t feel the pain at all.

Joint Fusion

Joint fusion, in general, is very rare. But it could be employed to fuse two bones together to relieve the inflammation from sacroiliitis pain.

Physical Therapy

There are certain physical therapy and stretches exercises that may decrease the pain. However, there are certain stretches too that can cause more inflammation in the sacroiliac joints.

Therefore, one should always try to hire some expert therapists to guide you the right way of doing physical exercises and stretches.
