Abstract

A prophylactic implant is provided for protecting osteoporosis-affected bone segments against fractures, in particular the neck of the femur, the vertebral column and the wrist. According to a proposed solution, the implant comprises a thin-walled hollow reinforcing body (1) having such a large number of passages (2) in its outer wall (3) that the ratio of the total area of the passages (2) to the total surface area is at least 1:2.
