Irritable hip syndrome is a condition that causes hip pain in infants and young children. It is most common in children between the ages of 3 months and 5 years old. The exact cause of irritable hip syndrome is not known, but it is thought to be related to changes in the structure of the hip joint and the muscles and ligaments that support it.
Studies have suggested that the most likely cause of irritable hip syndrome is a viral infection that causes swelling and inflammation of the hip joint. This swelling can cause the joint to become misaligned, leading to pain. Other factors that may contribute to irritable hip syndrome include genetics, congenital hip dysplasia, and trauma to the hip joint.
In some cases, irritable hip syndrome is caused by a bacterial infection that affects the hip joint. Bacteria can enter the joint through a wound or cut on the skin. They can also gain access to the joint through the bloodstream if the bacteria are present in the bloodstream. Treatment for bacterial infections usually involves antibiotics.
Another cause of irritable hip syndrome is a condition called Legg-Calve-Perthes disease, in which the blood supply to the hip joint is disrupted. This can lead to the breakdown of bone and cartilage in the joint, causing pain and swelling. Treatment usually involves medications to reduce inflammation, as well as physical therapy to help restore movement and strength in the hip.
In some cases, the cause of irritable hip syndrome is unknown. In these cases, treatment may involve physical therapy to help strengthen the muscles and ligaments that support the hip joint, as well as medications to reduce pain and inflammation. Surgery may also be recommended to correct any structural abnormalities in the hip joint.
