[About the proposition of strength of animal-experimental results with hip endoprosthesis. A comparative analysis of the stress of the upper thigh of man and of four-leg (author's transl)].
Precise knowledge of the biomechanic of the hip of man and of animal is necessary to evaluate the procedures of adaption of the femur after endoprosthesis with animal experiment and the transfer into the endoprosthesis of the human medicine. After functional-morphological and biomechanical researches (Pauwels), the upper femoral end of the man is highly stressed by bending at direct level while lowly stressed at sagittal level. The present own biomechanical analysis of the hip of the dog reveal - under consideration of the gaits "pace", "trot" and "gallop" - that the coxal end of the femur of the four-leg compared with that of man is highly stressed by bending at sagittal level as well as at direct level. The observations are herewith clearly explained that intense reconstructions of the bone at artificial human thighs are found mainly at lateral and medial circumference of the bed of the prosthesis, at animal experiment however at dorsal, ventral as well as medial circumference.
