Abstract
The improved endoprosthetic device surface treatment encourages soft tissue attachment thereto. A porous mesh surface treatment creates on an outer surface of the endoprosthetic device a three-dimensional surface structure similar to cancellous bone. Suture attachment features are provided at various locations around the treated surface structure to initially affix a vascularized soft tissue to the treated surface. As the patient heals the soft tissue grows and infiltrates the porous mesh surface to achieve an attachment strength substantially equal to the surrounding tissue.
Claims10
A bone endoprosthesis comprising:
- a prosthetic bone body segment sized and adapted to replace at least a portion of a natural bone, the body segment comprising an outer surface with a plurality of suture attachment features, the suture attachment features adapted to accept a tendon suture for affixation of a tendon thereto, each suture attachment feature comprising a through-hole feature for passage of a tendon suture therethrough, the through-hole feature located beneath the body segment outer surface;
- and
- a porous mesh surface adapted to encourage the infiltration of tendon collagen fibers for formation of an enthesis therewith, wherein the porous mesh surface is formed along a portion of the body segment outer surface that emulates the shape of the natural bone.
