Recesses in orthopaedic or surgical implants for containing a medication

Abstract

Abstract 1. An orthopedic or surgical implant formed with a recess for receiving substances which are effective as medicaments, for example, in fixing members of uncemented hip joint replacements, which substances are required to discharge into the surrounding tissue, characterised in that the recess (5, 6; 18) in the implant surface (7; 19) is closed by a porous cover (10, 24) of a porosity such as to permit the passage of substances and of liquids dissolving the same but to inhibit an invasion of tissue into the cover (10; 24) and recess (5, 6; 18).
