Case 3 An 18 year old white boy complains of right hip pain that is so severe he is unable to walk Multiple doses of ibuprofen have not helped He has a history of right hip problems since age 11 when he was diagnosed with LCP disease Physical examination reveals that the severe right hip pain is aggravated by movement He has been followed by an orthopedist who has discussed the possibility of hip replacement surgery Radiographs show avascular necrosis of the right femoral head with deformity of the right hip joint Figure 3 Pathophysiology and Etiology LCP disease is an osteochondrosis of the capital femoral epiphysis Osteochondroses occur when the blood supply to the epiphysis is interrupted In LCP disease disruption of blood supply to the capital femoral epiphysis causes infarction of the bone ie avascular necrosis and subsequent cessation of growth of the ossific nucleus The infarcted epiphyseal bone softens dies and is gradually absorbed Left untreated the epiphysis will eventually collapse from the pressure of the body s weight The body s reparative processes work to replace the dead bone with new bone and cartilage that grows in from the adjacent nonaffected viable bone Complete healing generally does occur but it may take up to 3 to 4 years 7
