We un FOHOWtreats and cures the sickness of Legg–Calvé–Perthes disease
Legg–Calvé–Perthes disease (LCPD ),
is a childhood hip disorder initiated by a disruption of blood flow to the head of the femur. Due to the lack of blood flow, the bone dies ( osteonecrosis or avascular necrosis ) and stops growing. Over time, healing occurs by new blood vessels infiltrating the dead bone and removing the necrotic bone which leads to a loss of bone mass and a weakening of the femoral head.
The condition is most commonly found in children between the ages of 4 and 8, but it can occur in children between the ages of 2 and 15. It can produce a permanent deformity of the femoral head, which increases the risk of developing osteoarthritis in adults. Perthes is a form of osteochondritis which affects only the hip. Bilateral Perthes, which means both hips are affected, should always be investigated to rule out multiple epiphyseal dysplasia .
Signs and symptoms
The condition is most commonly found in children between the ages of 4-10. Common symptoms include pain in the hip, knee (hip pathology can refer pain to a normal knee or ankle), or groin, exacerbated by hip or leg movement, especially internal hip rotation (with the knee flexed 90°, twisting the lower leg away from the center of the body). The range of motion is reduced, particularly in abduction and internal rotation, and the patient presents with a limp.
Pain is usually mild. Atrophy of thigh muscles may occur from disuse and an inequality of leg length. In some cases, some activity can cause severe irritation or inflammation of the damaged area, including standing, walking, running, kneeling, or stooping repeatedly for an extended period of time.
In cases exhibiting severe femoral osteonecrosis, pain is usually a chronic, throbbing sensation exacerbated by activity.
The first signs are complaints of soreness from the child, which are often dismissed as growing pains , and limping or other guarding of the joint, particularly when tired. The pain is usually in the hip, but can also be felt in the knee ( referred pain). In some cases, pain is felt in the unaffected hip and leg,
due to the children favoring their injured side and placing the majority of their weight on their "good" leg. It is predominantly a disease of boys (4:1 ratio). Perthes is generally diagnosed between 5 and 12 years of age, although it has been diagnosed as early as 18 months. Typically, the disease is only seen in one hip, but bilateral Perthes is seen in about 10% of children diagnosed.
