General Discussion

Legg-Calve-Perthes Disease (LCPD) is one of a group of disorders known as the Osteochondroses. The Osteochondroses typically are characterized by degeneration (avascular necrosis) and subsequent regeneration of the growing end of a bone (epiphyses). In Legg-Calve-Perthes Disease, the growing end (epiphysis) of the upper portion (capital) of the thigh bone (femur) is affected. Researchers believe that an unexplained interruption of the blood supply (ischemia) to the capital femoral epiphysis results in degeneration (avascular necrosis) and deformity of the thigh bone in this area. Symptoms may include a limp with or without pain in the hip, knee, thigh, and/or groin; muscle spasms; delayed maturation of the femur (delayed bone age); mild short stature; and/or limited movements of the affected hip. The disease process seems to be self-limiting as new blood supplies are established (revascularization) and new healthy bone forms (reossifies) in the affected area. Most cases of Legg-Calve-Perthes Disease occur randomly for no apparent reason (sporadically).
