This invention relates to a biodegradable implant including magnesium, wherein the magnesium contains, as impurities, (i) manganese (Mn); and (ii) one selected from the group consisting of iron (Fe), nickel (Ni) and mixtures of iron (Fe) and nickel (Ni), wherein the impurities satisfy the following condition: 0&#x3c;(ii)/(i)&#x2264;5, and an amount of the impurities is 1 part by weight or less but exceeding 0 parts by weight based on 100 parts by weight of the magnesium, and to a method of manufacturing the same.

Biodegradable implant and method for manufacturing same

The present invention relates to a magnesium alloy having controlled corrosion resistance properties, which comprises magnesium (Mg) and an alloying element and includes a magnesium phase and a phase composed of magnesium and the alloying element, wherein the difference in electrical potential between the magnesium phase and the phase composed of magnesium and the alloying element is greater than 0 V but not greater than 0.2 V.

Magnesium alloy

Disclosed is a bone fixation apparatus. This device comprises a bone screw having a head; a cap member placed on an upper part of the head of the bone screw; a receiver member having a bore in which the cap member and the head of the bone screw are respectively accommodated and held, and a U-shaped channel through which a support bar extends; and a compression member threadedly coupled into the receiver member to downwardly bias the support bar. A multitude of stepped portions are formed at a lower end and inner surface of the receiver member to be brought into linear contact with an outer surface of a lower part of the head so that the supporting force for the head of the bone screw is increased.
