A limb prosthesis which via coupling means (5) is adapted to be connected to an implant (6) in the form of an osseointegrated shaft projecting from an amputated stump (7). The coupling means (5) comprises a flexible joint and the prosthesis further comprises at least one force transmitting device (8) secured to and extending from a prosthetic member (4) connected to the coupling means (13, 14) up to a position on the amputated stump (7) or body portion to which the stump connects. The force transmitting device (8) is adapted to be secured to the stump or other body portion in such a way that it relieves the implant (6) from at least part of the bending and/or rotational forces exerted to the prosthetic member (4).
