Perthes disease
Legg-Calvé-Perthes disease (LCPD) is the name given to idiopathic osteonecrosis of the capital femoral epiphysis of the femoral head. The goal of treatment is to avoid severe degenerative arthritis
Sex: Males are affected 4-5 times more often than females.
Age: LCPD most commonly is seen in persons aged 3-12 years
Symptoms usually have been present for weeks because the child often does not complain.
· Hip or groin pain, which may be referred to the thigh
· Mild or intermittent pain in anterior thigh or knee
· Limp
· Usually no history of trauma
· Plain x-rays of the hip are extremely useful in establishing the diagnosis.
· Frog leg views of the affected hip are very helpful.
· Five radiographic stages can be seen by plain x-ray. In sequence, they are as follows:
· Cessation of growth at the capital femoral epiphysis; smaller femoral head epiphysis and widening of articular space on affected side
· Subchondral fracture; linear radiolucency within the femoral head epiphysis
· Resorption of bone
· Re-ossification of new bone
· Healed stage
Catterall staging is as follows:
· Stage I - Histologic and clinical diagnosis without radiographic findings
· Stage II - Sclerosis with or without cystic changes with preservation of the contour and surface of femoral head
· Stage III - Loss of structural integrity of the femoral head
· Stage IV - Loss of structural integrity of the acetabulum in addition
