Twelve cases of Perthes's disease operated on by intertrochanteric varus osteotomy with epiphyseodesis of the greater trochanter were followed on an average of 7 years and 5 months after the operation.
1) Satisfactory results were obtained in the cases operated on before 6 years of age.
2) The operation could be indicated for the late and regeneration stage of the disease, as for the early stage.
3) Development of high position of the greater trochanter appeared to be prevented by epiphyseodesis.
4) There were no significant differences in the anatomical results between the cases operated conservatively, but the periods of treatment were markedly reduced in the cases operated on.
