Abstract
【解決手段】 本装置は、大腿骨−膝関節人工装具402と脛骨膝関節人工装具404とを含んでいる。両人工装置は、膝関節人工装置装置を形成するべく生体内で接続可能なモジュール型コンポーネントで形成されている。大腿骨−膝関節人工装具が、二つの独立したコンポーネントである、側方顆406と中央顆408とを含んでいて、脛骨部膝関節人工装具は、複数の独立したコンポーネントである、中央ベースプレート432及び側方ベースプレート430と、中央インサート452及び側方インサート450とを含んでいる。
【選択図】 図1
Description
本発明における一つの利点は、コンポーネントのモジュール化により、外科医が中央又は側方顆用のサイズを選択する際により多くの融通性があることである。従って、これらの顆と脛骨プラトーの間における曲りは、運動範囲にわたって容易に等しくすることができる。従って、ソフトティッシュが容易にバランス可能となっている。
中央及び側方DPFCは、基端部18の端面30に設置された継手28を含んでいる。継手28は円筒状テーパ付き凹部形状である。これらの凹部は、大腿骨コンポーネントのボデーの中に延在している。
アンテリア及びディスタルポステリア大腿骨コンポーネント間における完全モジュール化は、外科医が、患者生来の歩行を弱体化するようなことを回避している。装置により、外科医はインプラント寸法を融通し調節することが可能になっている。
独立形ディスタル/ポステリアコンポーネントはMIS単一区画式人工装具として使用することができる。従って外科医は、手術中に単一区画式あるいは二区画式の選択をすることができる。
独立形アジア人用端部/後部コンポーネントは、アジア人の解剖学的構造体に対応する、単一区画式あるいは二区画式を可能としている。
