Early full weight bearing in femoral trochanteric fractures is an important problem. It seems to us to be imperative because the very old aged population (about 80 year old average) concerned by that type of fractures. That attitude reduces hospitalisation and rehabilitation time. The authors propose an original 95 degrees angular-plate rendered by a stay. A complete experimental study proved that material able to support the immediate weight bearing. A clinical application on 207 cases confirmed the experimental hypothesis.
