s e h t r e P r o f e r u C A e r e  Is Th Disease?
• Perthes disease, also known as Legg-Calve-Perthes Disease (LCPD), is a disorder that mostly affects children’s hips. Perthes disease falls in a group of disorders known as osteochondroses, in which there is degeneration along with ensuing regeneration of epiphyses (growing ends of bones). • In Perthes disease, the head of femur is affected, which is shaped as a ball. The femur (thighbone) is connected to the pelvic bone through ball and socket joint, where the head of femur (ball) fits into the socket (acetabulum). • This ball and socket joint provides mobility and flexibility to the hips/legs and helps in leg movement to various degrees.
• Perthes disease is a result of decreased blood supply to femur head that leads to necrosis and deformity of the femoral head. • The cause of decreased blood supply to femoral head is unknown, but theories have pointed toward genetics, malnourishment, thrombophilia (blood clotting disorder) and other environmental factors. • The necrosed bone takes several years to heal and regenerate, this condition resolves with the establishment of new blood supply, and a healthy bone is formed in the affected area without any intervention.
