本件出願は、「股関節置換人工補装具に適用する生物学的吸収性寛骨臼拘束体および物質ならびに股関節置換における安定性と機能を増強するための生体吸収性物質(BIOLOGICALLY ABSORBABLE ACETABULULAR CONSTRAINING COMPONENTS AND MATERIALSFOR USE WITH A HIP REPLACEMENT PROSTHESIS AND BIOABSORBABLE MATERIALS TOAUGMENT HIP REPLACEMENT STABILITY AND FUNCTION)」の名称で2002年4月9日に出願された米国仮特許出願第60/371,058号と、「股関節置換人工補装具に適用する生物学的吸収性寛骨臼拘束体および物質ならびに股関節置換における安定性と機能を増強するための生体吸収性物質(BIOLOGICALLY ABSORBABLE ACETABULULAR CONSTRAINING COMPONENTS AND MATERIALS FOR USE WITH A HIP REPLACEMENT PROSTHESIS AND BIOABSORBABLE MATERIALS TO AUGMENT HIP REPLACEMENT STABILITY AND FUNCTION)」の名称で2003年3月20日に出願された通常の米国特許出願第10/392,553号の利益を主張する。参考のために、上記両出願の開示は、本明細書中に援用される。
(発明の分野)
本発明は、人体の関節に適用する拘束部材に関する。その関節の例として、股関節、肩関節、肘関節および足関節が挙げられる。更に詳しく述べれば、本発明の局面は、修復外科手術後または置換外科手術後の関節の安定性と機能を少なくとも一時的に増強するための生物学的寛骨臼拘束部材および生物学的再吸収性寛骨臼拘束部材に関する。
図1は従来の股関節置換人工補装具を説明したもので、その補装具は、患者の骨盤12に接合させた寛骨臼陥凹/円胴10と、患者の大腿部16に接合させた大腿部材14または大腿幹部を含み、寛骨臼陥凹/円胴10と大腿部材14が球継手型連結体18で一体に連結されている。図2は、患者の骨盤12に接合させた寛骨臼円胴10の側面図を示す。その寛骨臼円胴は内部に着座した、ポリエチレン、金属またはセラミックで形成したインサート20を含む。
本発明は、外科手術後に人工股関節の球体面が位置ずれを起こすような場合、位置ずれ抑制を手助けできる拘束装置に関する。本発明の局面の一部は、股関節人工補装具の寛骨臼陥凹と大腿部材の相互間に付着させる生物学的物質および/または生物学的再吸収性物質から形成した人工股関節移植片に対して、拘束機構を適用することに関する。更に、本発明の局面は、組織形成(瘢痕組織形成などの)の速度を高めるとともに、股関節置換全体に対する宿主側の安定性に要する時間を増やすために、生物学的物質および/または生物学的再吸収性物質を適用することに関する。更には、本発明の局面は、瘢痕組織形成の速度を高めるのと同時に、股関節置換完了後の股関節に対する宿主側の安定性を高めるために、生物学的性状および/または生物学的再吸収性のペースト物質またはグルー物質(単独での使用または上記の何れかの局面との併用)を適用することに関する。更には、本発明の局面は、上記生物学的物質と生物学的再吸収性物質の何れかの物質に対して、凝固剤、瘢痕剤、造骨予防薬(抗異所骨化)、非ステロイド抗炎症薬(NSAID)および/または抗生物質などの有用薬剤を含浸させることに関する。更には、本発明の局面は、生物学的性状および/または生物学的再吸収性の安定剤の適用に関する。その安定剤は、単独での使用または前述の他の何れかの局面と併用した場合、寛骨臼から大腿部材の頚部に懸架して固定し、輪ゴム様に作用して大腿部材を運動させることができると同時に、結局のところ、瘢痕化を導いて永久に安定性を与える。更には、本発明の局面は、拘束機構を寛骨臼陥凹/円胴に取り付けるために、生物学的再吸収性のネジまたは他種固定部材(単独での使用または上記の何れかの局面との併用)を適用することに関する。更には、本発明の局面は、生物学的再吸収性の網目材またはウェブ材の適用に関する。その網目材やウェブ材は、単独で使用するか、または、上記の何れかの局面と併用した場合、大腿部材を寛骨臼または寛骨臼陥凹/円胴部材に保持させる。
本明細書中に記載する代表的実施態様は、股関節置換手術に適用される拘束装置、物質、および技術に関連する。当然のことだが、本明細書中に開示の装置、物質、技術が他形式の移植片や整形外科手術にも有用であることは当業者には明かである。
