Transient synovitis of the hip is a temporary irritation of the tissue that lines the hip joint. It can cause pain and difficulty when walking.
The cause of transient synovitis of the hip is unknown. It often happens after a recent cold or stomach virus but the virus is not suspected to be the cause.
Transient synovitis of the hip is more common in children aged 2-10 years. It is also more common in boys.
Symptoms may include:
- Pain and swelling in the hip (pain may also pass to the groin, thigh, or knee)
- Holding the leg and hip without moving (in infants and younger children)
- Difficulty walking and standing
- Refusal to bear weight on the affected leg
- Your child will otherwise appear well.
You will be asked about your child’s symptoms and medical history. A physical exam will be done.
There are many reasons for hip pain. Other more serious causes may be ruled out with further examination and tests such as:
- Blood tests—to look for potential infection of the joint.
- Images of the hip—to look for any damage to the tissue or bone of the hip.
Transient synovitis may be diagnosed if there are no other obvious causes of the hip problems.
Transient synovitis will usually pass on its own in 5-7 days. Rest and over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) will help manage discomfort.
Follow up appointments will be done to make sure the hip is improving as expected. Further testing may be done if the hip does not improve as expected.
