Abstract: A device for the reconstruction of skeletal defects with a flexible member, which is preferably resorbable, attached to a rigid structural prosthesis such as a dental implant, an orthopedic prosthetic implant, or an artificial disc implant. The cavitary space surrounded by the flexible member is filled with osteoconductive and/or inductive materials which eventually matures into bone. The prosthesis is supported by the bed of graft material surrounding it and is gradually unloaded as the bed matures into solid bone. The fixation of the prosthesis into native bone depends on the specific implant and the anatomic area of its use. The flexible member is secured to the margins of the prosthesis using rails, runners, sutures, or other attachment devices that prevent the escape of the bone graft and maintain an initial column of support for the implant.
