Analysis of the variations of the fixation of proximal part of the femur in the treatment of hip joint diseases in children using the apparatus

On the basis of a numerical experiment using the mathematical apparatus of finite element method on the computer IBM PC by means of program package «Microcomputeraided design of structures» modified for design of structures, applied in traumatology and orthopedics, a new method of the apparatus fixation if proximal part of the femur is developed. The arranging of Elizarov’s apparatus suggested provides the needle — rod fixation of the femur. The method is used in the treatment of 84 patients with hip joint diseases, positive results are obtained in 96,4% of the cases. The efficacy of the method allows recommending it for the treatment of patients with congenital dislocations of the femur, aseptic necrosis of the head of the femur and coxa-vara in specialized hospitals.
