What is synovitis?
Synovitis is a type of arthritis that causes hip pain and limping. It occurs in children prior to the onset of puberty and usually resolves on its own.
Hip pain (one side only)
Thigh pain, in front and toward the middle
Toxic/transient synovitis is diagnosed only after more serious conditions have been ruled out. Exams can include an ultrasound or X-ray of the hip, a complete blood count and in some cases, a bone scan and aspiration of hip joint fluid.
Children can limit activity to ease pain or soreness but may engage in normal activities as they like. Nonsteroidal anti-inflammatory medications may be prescribed to reduce pain. Generally the hip pain goes away in seven to 10 days. For persistent or more severe cases, your doctor may recommend a hip arthroscopy to remove the inflamed tissue.
