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.
Claims9
A bone endoprosthesis for replacing a humerus comprising:
- a prosthetic body segment having an upper end with a spherical insert for engaging a metal ball, a plurality of modular spacers, at least one of the plurality of modular spacers having a porous mesh surface treatment for soft tissue attachment on an outer surface thereof, a recess in the porous mesh surface, and a suture attachment feature adapted to accept a tendon suture for affixation of a tendon thereto, the suture attachment feature comprising a through-hole in the recess for passage of the tendon suture therethrough, the through-hole being located entirely beneath the outer surface of the porous mesh surface.
