prostheses family femoral prostheses including modular and monoblock prosthesis

The invention relates to a family of femoral prostheses intended for a medullary cavity of given dimensions, including: at least one piece prosthesis not lateralized (210) having a femoral stem (212) adapted to the dimensions of the medullary cavity, and a neck (214) having a first angular orientation of neck-shaft (A1) and a first femoral offset dimension (D3); at least one piece prosthesis lateralized (310) having a femoral stem (312) adapted to the dimensions of the medullary cavity and a neck (314) having a second angular orientation of neck-shaft (A2) different from the first angular orientation cervico-diaphyseal ( A1) and a second femoral offset dimension (D4); at least one modular femoral stem (12) adapted to the dimensions of the medullary cavity and having a cavity (22) for inserting a modular neck (14, 114); and a plurality of modular necks (14, 114) each having a lug (24) complementary to the insertion cavity (22).
