  • Patent number: 5645593
    Abstract: A prosthesis component having a surface intended, in use, to come into contact with bone tissue, wherein at least part of the external surface is textured to provide an array of lands or peaks (12, 12') separated by troughs (14, 14'), the troughs (14, 14') containing particles (20, 20') embedded in a biocompatible bonding material. The embedded particles (20, 20') preferably fill the troughs (14, 14') up to the level of the lands or peaks (12, 12'). This means that bone ingrowth into the lands or peaks (12, 12') and into the embedded particles (20, 20') can take place simultaneously, thus forming a rapid permanent fixing between the component and the bone with a reduced risk of dislodging of the component due to shear stresses and an increased tensile strength between the component and the adjacent bone.
