| Abstract: | Authors deal, on the basis of an analysis of 3 own cases and of the literary data, with the indication of Chiari's osteotomy in Perthes' disease. It is stated that the operation is to be performed over the age of 8-9 years, in severe lesion of the femoral head, and if the femoral head is so much flattened, widened and extruded from acetabulum that it can not be centralized with varisation. The operation promotes the rebuilding of the femoral head epiphysis, the biomechanical relations are improved and the early arthrosis can be prevented. |
