Perthes' disease is a form of idiopathic osteonecrosis (or osteochondrosis) of the femoral head in childhood (1).
- characteristically there is avascular necrosis of the epiphysis resulting in impaired enchondral ossification of the femoral head (2)
- it occurs principally in boys aged between 5 and 12 (3)
Presentation is with pain and limping, usually affecting just one hip, but occasionally both, developing over a month (1).
