[The biomechanical characteristics of the hip joint during endoprosthesis]

Under consideration was the interaction of the hip joint endoprosthesis pedicle with the femur. Causes of shaking the prosthesis pedicle, fracture of the femur, progressing deforming arthrosis were analyzed. Formulas for calculating the character of interactions of the prosthesis pedicle with the femur are presented, as well as risk factors and recommendations for practical use. The article is illustrated with a clinical case.
