Description
本出願は、2010年9月20日に出願された米国特許出願第61/384,399号明細書の利益を主張し、その出願の開示内容は本明細書に完全に記載されているものとして参照により本明細書に組み込まれる。
本開示は、概して整形外科用インプラントに関し、特に、柔軟な(compliant)整形外科用インプラントに関する。
健康な関節の動きパターンは複雑であり、回転および並進を、時には単独で時には組み合わせて含んでいる。したがって、瞬間的な回転中心または回転軸は、その関節とともに移動する。典型的な従来の関節形成(arthoplasty)インプラントは、通常、完全な(intact)解剖学的構造の生理学的な動きをよりよく再現する複雑な動きを具現化することに機能が限定され、したがって、解剖学的荷重に対して正確に反応しない。
一実施形態によれば、整形外科用インプラントは中心軸に沿って圧縮可能である。整形外科用インプラントは、第1部材と、第2部材と、第1部材と第2部材との間に接続された柔軟な接合部とを備えている。柔軟な接合部は、筋かい状に接続される少なくとも一対のばね部材を備えている。ばね部材は、中心軸に沿って第1部材を第2部材から間隔を空けて配置する。
図1および図2を参照すると、柔軟な整形外科用インプラント20を、脊柱の腰椎または頸部において、または要求に応じて脊柱のいずれかの別の位置において生体椎間板に置き換わることができる、椎間板インプラントとして構成することができ、または、指関節、股関節、肘関節、肩関節、手首関節、膝関節等、要求に応じてあらゆる人工関節として構成することができる。インプラント20は、中心軸22に沿って垂直に延在し、第1の隣接する骨に当接するように構成された第1端部部材24等の第1部材と、中心軸22に沿って第1端部部材24から垂直方向に間隔が空けられて配置され、第2の隣接する骨に当接するように構成された第2端部部材26等の第2部材と、第1端部部材24および第2端部部材26の間に結合されるとともにそれらに接続され得る、柔軟な中間接合部32とを備え、第1端部部材24および第2端部部材26を、中心軸22を中心に回転するように構成することができ、それにより、中心軸22は、第1端部部材24および第2端部部材26に対する回転の軸を画定することができる。たとえば、第1端部部材24および第2端部部材26の一方または両方は、整形外科用インプラント20の中心軸22を中心に他方の端部部材に対して回転することができる。
