Transient synovitis of the hip – Unpleasant for the child and Unsettling for the parent

Transient synovitis of the hip is the most common cause of abnormal walking in children. In other words, it is also called toxic synovitis and irritable hip. It is usually seen after a recent viral infection like a common cold. Although it can happen at any age, it is most often seen between 3 to 10 years of age. Boys are more commonly affected. However, there is nothing to panic, it recovers with rest over some time.

The exact cause is not known. It may be caused by the substances produced by the body’s immune system which fight against the recent viral infection.

It usually presents with sudden onset abnormal walking patterns or difficulty in crawling or difficulty in standing. Most often one side is affected. Older children complain of pain in the groin, hip, thigh or knee. In addition, children feel unpleasant and refuse to walk. However, children are fine with a nontoxic look.

Transient synovitis of the hip will get better with rest. Mild non-steroidal anti-inflammatory drugs such as ibuprofen or acetaminophen are enough to aid in the recovery.
