Car crashes can cause many different types of injuries that can change a victim’s life. One such condition is called sacroiliac joint dysfunction. People with this condition have pain in their lower back, hips, and thighs. According to, a leading pain management publication, sacroiliac joint dysfunction is very comparable to – but not the same as – sciatica. As car accident victims are thrown about the car or into other passengers, the sacroiliac joint can be injured.

The anatomy of the sacroiliac joint

The sacrum is a triangular bone at the end of the spine. The iliac bones are the two large bones that make up the pelvis. The sacroiliac joint connects the sacrum to the iliac bones or crests. The sacroiliac joint helps people bend and absorb shock. In a normal anatomy, ligaments support the sacroiliac joint. The gluteus maximus muscle and the piriformis muscle also support the sacroiliac joint.

Types of pain common to a sacroiliac joint dysfunction

Spine-health claims that up to 30% of lower back pain diagnoses are due to sacroiliac joint dysfunction. A normal sacroiliac joint can withstand a lot of force to the upper body, the legs, and the pelvis. A dysfunctional sacroiliac joint means the joint moves too little or too much.

  • Too little motion. (Hypomobility) This can cause pain and muscle tension. It can make mobility difficult. Symptoms include pain on just one side of the lower back or buttocks. Like sciatica, the pain can radiate down the back of a car accident victim’s leg.
  • Too much motion. (Hypermobility). With this situation, the patient feels like the pelvis isn’t stable. Symptoms include lower back or hip pain which can radiate into the groin.

Dysfunction of the sacroiliac joint can also cause inflammation.
