Congenital Hip Dysphasia and Perthes’ Disease
This condition affects newborn babies and is much more common in girls than in boys. It often affects babies who are born by breech delivery, which puts excessive strain on their hip joints. In mild cases, there is a looseness of the ligaments around the hip joint, which results in excessive flexibility. In very severe cases, the hip joint is permanently dislocated. Hip dysphasia may correct itself within weeks of the baby’s birth, but a plaster cast might need to be worn for up to six months. Corrective surgery may be necessary in some cases.
Congenital hip dysphasia may be due to weakness of the hip joint ligaments or, in more severe cases, to an abnormality in the hip socket. If the problem does not right itself within the first few weeks, it is vital that the affected head of the femur is correctly positioned in the hip socket, so that the hip can develop normally. The orthopedics specialist will use a harness or a plaster cast to keep the hip in correct alignment and this may need to be worn for six months.
Perthes’ disease: Perthes’ disease is a rare condition in which the head of the femur breaks down and gradually reforms over about two years. The condition tends to occur in boys between the ages of four and eight. Typical symptoms are limping and pain in the hip or knee. Doctors do not know why children develop perthes’ disease, but it may be due to disrupted blood supply to the femur. If your child has an unexplained limp, you should arrange to see your doctor about it.
