What is irritable hip?

Irritable hip is a common cause of hip pain and limping in children who have not yet reached puberty. Although the symptoms may be alarming, it does not usually last for more than a few weeks.

It is also known as acute, transient synovitis.

The tissues around the hip joint swell, normally in one hip only, and pain may spread from the hip to the groin, thigh, and knee.

Boys are two to four times more likely to have irritable hip than girls. It often appears about 2 weeks after a viral illness, especially of the upper respiratory tract, but experts do not know why it happens.

What are the symptoms of irritable hip?

Irritable hip involves hip pain that tends to start suddenly, usually on one side of the hip. Pain may range from mild to severe.

Acute transient synovitis is a common source of hip pain in children.

The pain spreads, possibly to the groin, the thigh, and the knee on the affected side.

A limp can develop because of the pain.

Young infants may crawl or cry in an unusual way because of the pain. This may be more noticeable when changing diapers.

A slight fever sometimes occurs, but this is less common. If the fever is above 101 degrees Fahrenheit, it is likely the child has another problem, which may be more serious.

What are the causes of irritable hip?

In acute, transient synovitis, the synovial membrane that surrounds the hip becomes inflamed or swollen, but it is not clear why this happens.

In many cases, the child has a viral infection, usually of the upper respiratory tract, about 2 weeks before the symptoms of irritable hip appear. This could be a cold or sore throat.

A fall or an injury may also cause it.

Poor blood flow can cause the head of the femur, or thigh bone to become damaged. This part of the femur is the ball in the ball-and-socket hip joint. This is called Perthes' disease, and it can cause irritable hip.

Diagnosis of irritable hip

The doctor, usually a primary care physician, will ask the child or parent or guardian about symptoms. This will be followed by a physical examination, and possibly an X-ray, imaging scan or blood test. The blood test will detect any infection.

What is the treatment for irritable hip?

With rest, the problem will resolve within a few weeks, without needing to spend time in the hospital.

The doctor may recommend paracetamol, such as Tylenol, for pain. Children under 16 years of age should not take aspirin.

In the hospital, the child may be put on a traction, which means the leg is kept rested by applying a pulling force to the leg taking tension off the hip and alleviating pain and spasm.
