An acetabular socket having an inner face for receiving the head of a femoral prosthetic component, said inner face being of hemispherical shape extended by a part-cylindrical section of radius equal to the radius of the hemisphere, the axial length of a first circumferential part of the part-cylindrical section being greater than that of a second circumferential part of the part-cylindrical section. Said socket is designed for mounting in the pelvis with the first circumferential part at the posterior to limit backward movement of the femoral prosthetic component, while the shorter, second circumferential part at the anterior allows a good range of forward flexion of the femoral prosthetic component.
