Abstract
Isoelastic implants are provided with a surface roughness for anchorage in and load transmission to the surrounding tissue. The surface roughness is formed of one or more of the structures including undulations, or grooves, or pores, or lacunae, or gaps and protrusions. The roughness is located at two separate and confined regions along the surfaces of the implant which are intended for transmitting loads from the surrounding tissue into the implant or vice versa. The regions for containing the roughness are confined to two small areas at the opposite ends of the implant's surface. The ends are defined in relation to the direction of the load to be transmitted through the surfaces.
