Retrospective analysis of treatment of 183 patients, aged 1 month-18 months, with congenital hip dislocation was performed. 146 patients had failed hip reduction. It was detected that in 134 cases (91.8%) inadequate treatment and/or wrong management and behavior of parents took place. Failed treatment with Frejka pillow, abductive splint, Pavlic device, functional plaster bandage, closed reduction were considered. Main mistakes in application of those methods as well as violation of treatment tactics were described. It was shown that repeated failed femoral head reductions were unfavorable factors for the following development of hip joint.
