[Legg-Calvé-Perthes disease].

Legg-Calvé-Perthes disease (LCPD) is a necrosis of the capital femoral epiphysis that occurs during the growth stage and evolves in consecutive stages with varying degrees of intensity and extension. It is self-limited, caused by ischemia of unknown origin, and involves a complex course, from the time of diagnosis to the decision of providing treatment. The latter needs to be understood for it to be effective and delay or prevent the occurrence of the pain resulting from the arthrosis that may occur as a sequela.
