A device for anchoring prostheses comprises a securing member (1) to be secured in bone tissue, a support member (2) for supporting the prosthesis and means for interconnecting the securing member and support member. The support member and securing member comprise co-operating surfaces (10, 11), which are complementary concave and convex respectively and arranged to allow adjustment of the position of the support member relative to the securing member, the adjusted position being fixable by the connection means. The securing member comprises a thread for screwing into the bone tissue. The thread is a trapezoidal thread or a round thread. |
