The hip development after surgical treatment of congenital dislocation of the hip in children under school age

The results of roentgenological examination have been analyzed in 21 patients (26 joints) at the age of 2-6 years with congenital dislocation of the hip, who were subjected to closed reduction of their dislocation with the Ilizarov fixator and subsequent reconstruction of pelvic and hip components. Soft-tissue blocking had place in all the cases, it was preserved during the performance of reconstructive procedures, during rehabilitation period and gradually regressed at 1/5-2 years after the fixator removal. Using the technology of the cavity transposition, worked out at the Centre, afforded sufficient articular stability under the conditions of soft tissue remained interposition and created conditions for subsequent development of the joint. Acetabulum formation in children under school age after closed reduction of dislocation mainly occurred as the increase of acetabular top part slope and the change of acetabular shape. Dysplasia signs of acetabulum remained in all the cases as thickening of its bottom.
