Sacroiliitis

Sacroiliitis is the name of inflammation of the sacroiliac joint.  The sacroiliac joint connects the lower spine and pelvis.

Signs and symptoms of sacroiliitis depend on the underlying cause but may include:

  • Pain and stiffness in the lower back or buttocks, especially in the morning
  • Arthritis affecting the hips and shoulders
  • Psoriasis, an inflammatory skin condition

A doctor may confirm a diagnosis based on:

  • X-rays of the sacroiliac joints
  • Magnetic resonance imaging (MRI) scan

Treatment depends on the signs and symptoms as well as the underlying cause and may include:

  • Nonsteroidal anti-inflammatory drugs, such as indomethacin (Indocin), ibuprofen (Advil, Motrin, others) and naproxen (Aleve, Anaprox, others)
  • Corticosteroids, such as prednisone
  • Physical therapy to help manage pain and stiffness
  • Antibiotics, if the cause is infection
