The authors describe three fractures of femoral stem which occurred in a series of 200 cemented total hip prostheses type Weller (derived by Charnley-Mueller). All these three prostheses have been applied in patients who at operation weighed more than 96 kg. The level of the fracture always happened at the same height between 8 and 9.2 cm, in the point where loosening and cement fracture occurred. They attribute the mechanical failure to the increased body weight because the prostheses had been applied in the normal position and were perfectly cemented.
