ABSTRACT:
When a femoral prosthesis, mounted in the femur, by cement, has been in use for some years, the upper part thereof can become unsupported and fracture of the stem near its mid-point can occur. To minimize this possibility, a flange is provided on at least one side of the stem of the prosthesis to ensure better load transfer to the cement and thus the bone. To prevent shear forces causing such separation at the concave surface of the stem of the prosthesis, this can be provided with serrations to discourage separation.
