Long-term results of conservative treatment of 612 children (710 joints) with congenital hip dislocation showed that the highest complication rate was detected in Lorenz procedure. Authors suggest the device to reduce hip dislocation without traumatization but with preservation of joint movement during treatment. Movements rotating the hip inside promote epiphysis centration into acetabulum that decreases the risk of dystrophic process development. In 91.4% of cases excellent and good results were achieved in children over 4 months who were treated using that device in combination with physiotherapy. Rational tactics for conservative treatment of congenital hip dislocation was elaborated. Authors believe that the suggested treatment complex allows to delay by 10-15 years the early coxarthrosis development in children and adolescents.
