Abstract


In their study the authors received data about strain distribution and values of fragment movement in a nonunion fracture model of the distal femoral metaepiphysis in conditions of three types of its fixations: with a blocked intramedullary rod, a plate with angle stability, and a plate with a 95 degree blade plate. The contact area between fragments was 50%. The load application area corresponded to the natural load on the femur in a standing position and during flexion in the knee joint. A variant of rotation loading was examined too.
