Abstract: A femoral hip prosthesis has a body having a body lateral face, a body medial face, a body front face and a body rear face. A stem extends longitudinally from a lower end of the body along a central stem axis. A neck extends from an upper end of the body along a central neck axis inclined at an obtuse angle to the central stem axis. The body lateral face is provided with a series of longitudinally spaced lateral face teeth transversely extending between the body front face and body rear face. Each of the lateral face teeth has an upper face inclined with respect to an adjacent tangent of the body lateral face by between 60 and 120 degrees.
