Abstract

1416267 Bone implants SULZER BROS LTD 31 Jan 1973 [2 Feb 1972] 4835/73 Heading A5R The shank of a bone implant has a narrowing cross-sectional area towards one end thereof and an external non-porous surface having discrete unconnected depressions therein between raised portions of said shank, said depressions being between 10 Ám and 100 Ám in depth. The shank may have a plurality of side walls and a distal end portion of generally trapezoidal cross-section, at least two of the side walls having depressions therein. The external surface of the shank including the depressions may be roughened e.g. by sand blasting.
