より多くの患者にフィットし、アプローチを選ばないデザインアコレードII は新しいデザインコンセプトの人工股関節システムです。独自のSOMA※テクノロジーを使用することで人体計測データに基づいたデザインを実現しました。ストライカーは股関節、膝関節また骨折治療材料などの整形外科用インプラントをデザインするためにこのテクノロジーを開発しました。SOMAには多様な人々の計測データが蓄積され続けています。THA患者層の変化に対応するために、アコレードII は最新の計測データにより幅広い骨のサイズと形状に適合するデザインとなっています。1）, 2）

モルフォメトリックウェッジ － Morphometric Wedge －テーパーウェッジステムは 1970 年代のセメント型 Mueller ステムが原型とされています。全てのサイズにおいて内側カーブが一定で外側に向けてサイズが大きくなるのが特徴でした。アコレード II は初のモルフォメトリックウェッジデザインで、当社従来型テーパーウェッジステムの進化型です。今日、患者の骨の大きさや形状は多岐にわたることが確認されていますが、1）, 2）それらに幅広く適合するようにステムの内側カーブはサイズ毎に設定されています。工学試験の結果、このデザインは初期固定性に優れ、3）また大腿骨近位部に荷重伝達が促進されることが明らかになりました。アコレードII 大腿骨ステムは全置換、もしくは部分置換（人工骨頭置換）に使用できます。

効率化を促進THA の普及に伴い、効率化は一層重要になってきました。アコレード II は手術手技の流れに沿った 2 つのトレーとブローチオンリーの簡便な器械システムで、術者とスタッフのために手術室の効率化をサポートします。また毎手術後に滅菌する器械の数も少なくすることができます。1)Wuestemann T, Bastian A, Schmidt W, Cedermark C, Parvizi J, Rothman R.
