Abstract
Slipped capital femoral epiphysis - coxa vara adolescentium - is a hormonally determined disease, which may lead to permanent consequences in the form of early coxarthrosis, sometimes up to disability in the young adulthood, if wrongly or lately dia-gnosed. In the clinical picture chronic or acute groin pain is typical, but thigh or knee pain may be misleading.
In order to put up the diagnosis an x-ray of both hips in two projections (anteroposterior and "axial") is essential. Therapeutically in the case of acute overlaps we endeavour to achieve a reposition and epiphyseodesis, in the case of chronic overlaps (over 30° in one of the planes) we solve the condition through multi-plane corrective osteotomy with the effort to achieve the correct position of the epiphysis.
Anyhow the patient is endangered by coxarthrosis - namely through the mechanism of femoroacetabular impingement - the mechanic conflict between the wrong form of the femoral head and the margin of the fossa.
