Risk Factors for Sacroiliitis: Who Is Most at Risk?
Sacroiliitis is inflammation of one or both sacroiliac (SI) joints, which connect the lower spine (sacrum) to the pelvis. It can cause pain in the lower back, buttocks, hips, and sometimes the legs.
But why does sacroiliitis develop in some people and not others?
Several factors can increase the risk of developing sacroiliitis. Understanding these risk factors can help people recognize symptoms early and seek appropriate medical advice.
What Is Sacroiliitis?
The sacroiliac joints are located on both sides of the lower spine. They help transfer the body's weight between the upper body and the legs and provide stability during walking and other movements.
Sacroiliitis occurs when one or both SI joints become inflamed. The inflammation may be related to injury, infection, pregnancy-related changes, or inflammatory diseases.
Who Is Most at Risk of Sacroiliitis?
1. People With Inflammatory Arthritis
One of the important risk factors is having an inflammatory condition affecting the spine and joints.
Examples include:
Ankylosing spondylitis
Axial spondyloarthritis
Psoriatic arthritis
Reactive arthritis
Inflammatory bowel disease-associated arthritis
These conditions can cause inflammation around the sacroiliac joints.
2. People With Previous SI Joint Injury
A direct injury to the pelvis or lower back may damage or irritate the SI joint.
For example:
Falls
Road traffic accidents
Sports injuries
Direct blows to the pelvis
Sudden twisting injuries
Repeated stress on the joint can also contribute to symptoms.
3. Pregnancy
Pregnancy can increase stress on the sacroiliac joints.
Hormonal changes can make the pelvic ligaments more flexible, while increasing body weight and changes in posture place additional stress on the pelvis.
Some women may therefore experience SI joint pain during pregnancy or after childbirth.
4. Repetitive Physical Activity
Activities involving repeated lifting, twisting, bending, or heavy physical work may increase stress on the SI joints.
People who regularly perform activities such as:
Heavy lifting
Running
Contact sports
Repeated bending
Repetitive twisting
may experience increased mechanical stress around the pelvis.
5. Leg-Length Difference
A significant difference in leg length can affect the way the pelvis is positioned and how forces are transferred through the SI joints.
Over time, altered biomechanics may contribute to pain or irritation around the joint.
However, leg-length difference is not always the cause of sacroiliitis, and other conditions should also be considered.
6. Previous Surgery or Fusion of the Spine
People who have undergone certain spinal surgeries or spinal fusion procedures may experience changes in the distribution of forces through the pelvis.
These biomechanical changes can sometimes increase stress on the SI joints.
7. Infection
Although infectious sacroiliitis is uncommon, infection can affect the SI joint.
The risk may be higher in people with certain infections, bloodstream infections, recent surgery or invasive procedures, or conditions that weaken the immune system.
Infectious sacroiliitis can cause severe pain and fever and requires prompt medical assessment.
8. Inflammatory Bowel Disease
Conditions such as Crohn's disease and ulcerative colitis can be associated with inflammation of the sacroiliac joints.
Some people may develop SI joint inflammation even when bowel symptoms are mild or not currently active.
9. Psoriasis and Psoriatic Arthritis
People with psoriasis or psoriatic arthritis may have inflammation affecting the spine and sacroiliac joints.
Persistent lower back or buttock pain in someone with psoriasis should therefore be discussed with a healthcare professional.
10. Family History
Some inflammatory forms of sacroiliitis are associated with genetic factors.
A family history of conditions such as ankylosing spondylitis or axial spondyloarthritis may increase the likelihood of developing these disorders.
One commonly discussed genetic marker is HLA-B27. However, having HLA-B27 does not mean that a person will definitely develop sacroiliitis.
Is Age a Risk Factor?
Age alone does not determine whether someone will develop sacroiliitis.
Inflammatory sacroiliitis can occur in younger adults, while degenerative changes and mechanical problems involving the SI joints may become more relevant with increasing age.
Therefore, the cause of the SI joint problem is more important than age alone.
Is Sitting for Long Hours a Risk Factor?
Long periods of sitting can contribute to lower back and pelvic discomfort, but sitting alone does not necessarily cause inflammatory sacroiliitis.
If someone has persistent SI-region pain, it is important to identify the actual underlying cause rather than assuming that prolonged sitting is responsible.
Common Risk Factors at a Glance
| Risk Factor | How It May Affect the SI Joint |
|---|---|
| Inflammatory arthritis | Can directly cause SI joint inflammation |
| Previous pelvic injury | May damage or irritate the joint |
| Pregnancy | Increases pelvic stress and ligament flexibility |
| Heavy physical activity | Can increase mechanical stress |
| Repetitive twisting | May irritate the SI region |
| Leg-length difference | May alter pelvic biomechanics |
| Spinal surgery | Can change load distribution |
| Infection | Can cause infectious sacroiliitis |
| Inflammatory bowel disease | May be associated with axial inflammation |
| Psoriatic arthritis | Can involve the SI joints |
| Family history | May increase risk of inflammatory disease |
When Should You See a Doctor?
You should seek medical evaluation if you have persistent lower back or buttock pain, particularly when it is associated with:
Morning stiffness
Recurrent pain
Pain that interferes with walking or daily activities
Fever or chills
A recent injury
Known inflammatory arthritis
Psoriasis
Inflammatory bowel disease
Severe or rapidly worsening pain
A healthcare professional may use a combination of medical history, physical examination, blood tests, and imaging to determine the cause.
MRI can be useful when active inflammation of the sacroiliac joints is suspected, particularly in inflammatory forms of sacroiliitis.
Can Sacroiliitis Be Prevented?
Not every type of sacroiliitis can be prevented, especially when it is related to autoimmune or inflammatory diseases.
However, maintaining good physical conditioning, avoiding unnecessary injury, using proper techniques during heavy lifting, and managing underlying inflammatory conditions may help reduce problems related to mechanical stress.
Final Takeaway
Sacroiliitis can affect different people for different reasons. Important risk factors include inflammatory arthritis, previous injury, pregnancy, infection, repetitive physical stress, inflammatory bowel disease, psoriasis, and certain genetic factors.
Having one or more risk factors does not automatically mean that a person has sacroiliitis. Persistent symptoms should be evaluated by a qualified healthcare professional to determine the correct diagnosis and treatment.
