Legg-Perthes-Calvé disease (LPC) or primary hip osteochondritis (PHO) is an ischemic necrosis of the upper femoral epiphysis. It was described in 1910 simultaneously by Legg in the USA, Calvé in France, Perthes in Germany and Waldenstroem in Sweden. It is a serious and disabling disease. It attacks the upper extremity of the growing femur, and evolves in four phases: condensation, fragmentation, repair, and deformation. The frequency of this disease is not well known and varies according to the authors between 1 in 2000 in Europe and 1 in 5000 in black Africa. Legg-Perthes-Calvé disease is a hip disorder of children between three and ten years of age, with the majority of cases occurring in children under 14 years of age. The sex ratio is 4 boys to 1 girl and the mean age of diagnosis is 6.5 years. We report the observation of a 13 year old female patient who presented for 4 years after a road accident with mechanical pain involving the hips.
