Risk Factors

Transient synovitis of the hip is more common in children between who are between 3 and 8 years of age. It is also more common in boys.


Symptoms may be:

  • Sudden pain in the hip, groin, or thigh
  • Pain when putting weight on the side that has pain
  • Limping or avoiding walking and standing


The doctor will ask about the child's symptoms and past health. A physical exam will be done. This is often enough to make the diagnosis.


Transient synovitis often goes away on its own in three to ten days. The goal will be to manage symptoms during this time. This can be done with rest and over the counter pain medicine.


There are no current guidelines to prevent transient synovitis of the hip.
