Abstract
Description
インプラントは、ヒト及び/または動物において1つ以上の骨を支持及び/または固定するために使用され得る。例えば、インプラントは脊椎において使用されて、脊椎の椎骨間の損傷した組織を支持及び/または置換し得る。インプラントが、2つの椎骨間に埋め込まれると、その2つの椎骨間に支持体を提供し得、骨成長が、長期の支持のために、これら2つの椎骨を少なくとも部分的に融着するためにインプラント周辺及びインプラントを通って生じ得る。インプラントは、剛性材料と共に、例えば、端板と相互作用する範囲の50%を覆い得る比較的大きなリムを含み得る。リムは、インプラントと椎骨の端板との間の接触範囲を提供し得る。大きなリムは、いくつかの欠点を有し得る。例えば、大きなリムは、骨成長を妨げ得、上位椎体及び下位椎体を融着する骨柱のサイズを低減し得る。
