Description

膝假体***
本申请为2011年1月21日提交的专利申请“膝假体***”（申请号：201110031384.X，申请人：德普伊产品公司）的分案申请。
背景技术
本公开总体上涉及外科手术装置和手术，更具体地讲，涉及可植入的全膝置换假体。
在全膝置换（TKR）手术中植入患者体内的被最广泛使用的类型的膝假体包括三个部件：金属股骨部件，其附着于股骨远端；金属胫骨部件（或托盘），其附着于近端胫骨；以及聚合物（UHMWPE）***件（也称支承件或镶嵌物），其安装于股骨部件和胫骨部件之间。还可获得与这些膝假体的一些结合使用的各种类型的髌骨置换物。膝假体的两种类型为：用于当后交叉韧带不再有活力时使用的后稳定型（PS）假体以及（后）交叉韧带保留型（CR）膝假体。这两种类型的膝假体的每一种可设置为固定支承膝假体，其中***件不相对于胫骨部件运动，或者设置为活动支承膝假体，其中***件在胫骨部件的光滑平台上旋转。使用活动***件还是固定***件很大程度上取决于患者的膝韧带和其它软组织的状况。
膝假体***可包括多种尺寸的股骨、胫骨和***件部件，以适应全世界TKR患者群体中患者解剖结构的不同。膝假体***的设计需要在许多重要因素间权衡，所述因素涉及（仅例举一些）运动性能、临床结果、植入物耐久性、成本和易用性。关于膝假体的运动性能和寿命二者的重要考虑是股骨部件支承表面和***件支承表面之间的型合度。
研究人员通常将冠状面或矢状面的型合度表征为股骨部件的股骨髁的凸面半径与相接的***件表面的凹面半径的比率。型合率为零代表平坦的***件表面，对应于高负载下的非常高的接触应力。型合率为0.99代表高型合度，通常对应于高接触面积、相对低的接触应力，以及随之而来的***件聚乙烯表面的磨损率降低。
研究人员已经发现冠状面的型合度对假体寿命的影响可能会大于矢状面的型合度对假体寿命的影响。例如，在Kuster等人的论文“Theeffectsofconformityandloadintotalkneereplacement（在全膝置换中型合度和负载的影响）”(ClinicalOrthopaedicsandRelatedResearch（临床整形外科和相关研究），第375期、302-12页，2000年6月)中，作者发现压缩表面应力、剪切应力和vonMises应力受到型合率改变的影响，而受负载变化的影响较小。在更新近的Berend等人的论文“EffectsofcoronalplaneconformityontibialloadinginTKA:acomparisonofAGCflatversusconformingarticulations（在TKR中冠状面型合度对胫骨负载的影响：AGC平坦与型合关节连接的比较）”(SurgicalTechnologyInt.（外科手术技术），第18期，第207-212页，2009年)中，作者研究了型合度对患者的近端胫骨负载的影响。近端胫骨的不合适的负载可导致胫骨部件在胫骨中的无菌性松动，并最终导致假体失效从而需要修复手术。作者发现冠向凹形扭曲部件造成胫骨前内侧的应变增大，同时造成胫骨后侧的应变显著减小。他们还发现在型合与平坦关节连接中近端胫骨应变减小并集中。
但是，本领域中周知的是，非常高的型合度也可引起（例如）***件表面的不良负载状况，或者引起对股骨部件的过度约束，从而抑制了对于关节性能和患者舒适度而言重要的关节运动。因此，只要应力低于***件材料的屈服强度，则用接触面积的中间值来设计可以是最佳的，以达成关节松弛和型合率的最佳组合。
全世界的TKR患者群体的患者解剖结构不同，这使膝假体设计者面对的挑战复杂化。具有较小股骨的体型较小的患者明显需要较小的膝假体。与用于体型大的患者的大股骨部件相比，小股骨部件的股骨部件内外髁各自具有更小的冠状半径。为了保持合适的型合率以及包括髁间距在内的其它几何关系，小股骨部件必须与合适尺寸的***件匹配。然而，除了大范围的患者尺寸之外，股骨和胫骨之间的尺寸比例也变化很大。例如，对于给定尺寸的近端胫骨，一些患者具有比其它患者更大的股骨远端。在这种情况下，当使用目前可用的膝假体***时，医生可能需要选择植入与股骨稍微不匹配而与***件匹配的股骨部件，或者与股骨匹配而与***件稍微不匹配的股骨部件。
因此，根据上述考虑，需要这样一种膝假体***，其允许医生选择与特定患者的股骨尺寸相符的股骨部件、与胫骨尺寸相符的胫骨部件以及与股骨部件最佳匹配并与胫骨部件相容的***件。这种膝假体***应当包括固定类型和活动类型的假体这二者，并用于CR和PS这两种手术。此外，所述***应当顾及全世界患者群体的患者解剖结构的各种变化。
除了提供最佳匹配的膝假体部件之外，还存在保持和降低膝假体***的成本和复杂度的持续需要。膝假体***可包括多种尺寸的、各用于左右膝的股骨部件、胫骨部件和***件，以适应患者解剖结构和状况的变化。此外，每个***件可具有多种厚度，从而医生可选择引起合适关节张力的一种。因此，膝假体制造商必须提供代表大量不同尺寸组合的非常大的部件库存，以顾及世界范围的患者群体。因此，需要允许部件可互换的改进的膝假体***，以用最少量的部件得到必要的尺寸组合。
膝假体***设计过程中的另一考虑是对于PS股骨部件植入的骨预备。PS和CR股骨部件这二者均有一对分离的髁，所述髁与股骨远端的自然髁在一定程度上相似。对于PS股骨部件，位于髁之间的盒状物（或髁间窝）包括与PS***件上的棘突相互作用的特征。PS股骨部件的植入需要在股骨远端切割凹槽以接纳所述盒状物。在一些当前的膝假体***中，对于所有的PS股骨部件尺寸来说，盒状物的尺寸都是相同的，从而需要在股骨远端切割相同尺寸的凹槽，即使对于较小的股骨也是一样。然而，如果可能的话，最好在为了附连股骨部件的股骨的预备期间保存自然骨骼。因此，还需要这样一种膝假体***，其在解决前述需要的同时，每个PS股骨部件具有其尺寸相对于股骨尺寸按比例确定的盒状物。
膝假体***设计过程中的另一考虑是为胫骨部件植入而进行的骨预备。目前可获得的活动和固定的TKR假体***包括一定范围内的解剖尺寸的胫骨部件。对于这些***中的一些，用于特定尺寸的活动TKR假体的胫骨部件具有与同样尺寸的固定TKR假体的构造不同的构造。具体地讲，支持固定支承***件的平台的形状可以不同于支持活动支承***件的平台的形状。这可导致切除的胫骨平台表面的覆盖范围发生小的（但可能是显著的）差异。虽然不尽理想，医生可通过选择较大尺寸的胫骨部件来获得期望的胫骨覆盖范围。更理想的是，设有活动和固定胫骨部件的TKR***具有针对与周围组织的相互作用、运动性能等而优化的通用平台轮廓形状。
另外，目前可获得的TKR***设有这样的胫骨部件，其具有可变长度的柄部以适应不同胫骨状况。此外，活动胫骨部件柄部的构造可以不同于固定胫骨部件柄部的构造。接着，这类***要求有大量不同的扩孔工具用于各外科手术。优选的TKR***会包括具有不同长度柄部的活动和固定胫骨部件，但是不要求用于预备胫骨的若干个不同的扩孔工具。这还为医生提供选择合适类型的胫骨部件的术中灵活度，同时减少在外科手术中需备用的器械数量。

以下文献全文以引用方式并入本文中。
美国专利7,628,818，标题为“Fixed-BearingKneeProsthesisHavingInterchangeableComponents（具有可互换部件的固定支承膝假体）”，由Hazebrouck等人(以下称“Hazebrouck”)于2007年9月28日提交，并于2009年4月2日公布。
美国专利申请No.12/165582，标题为“Posterior-StabilizedOrthopaedicProsthesis（后稳定型整形外科假体）”，由Wyss等人(以下称为“Wyss”)于2008年6月30日提交。
Hazebrouck公开了固定支承膝假体***，其中不同尺寸的***件各自可与每种尺寸的胫骨部件相容，使得医生可选择其尺寸针对患者胫骨适当确定的胫骨部件以及与股骨部件匹配的***件。
Wyss公开了这样一种膝假体***，所述膝假体***具有多种尺寸明显不同的PS（固定或活动）***件，所述***件具有从下表面向上延伸的棘突。所述棘突的后侧具有凹陷凸轮面和突起凸轮面。每个PS股骨部件具有一对间隔开的髁，所述髁限定具有后凸轮的髁间窝。后凸轮包括凹陷凸轮面和突起凸轮面。在第一阶段的屈曲过程中，后凸轮的凹陷凸轮面接触棘突的突起凸轮面，在第二阶段的屈曲过程中，后凸轮的突起凸轮面接触棘突的凹陷凸轮面。
图1-16示出了在图17中示出的膝假体***100的各部件。这些部件中的每一种均可有多种尺寸，并且可如下所述地匹配到一起，从而为医生提供大量的尺寸组合。通过利用膝假体***100，医生可针对大的患者群体中的每个患者选择正确匹配患者的股骨和胫骨这二者的尺寸组合。也就是说，股骨部件的尺寸被定得明显不同以配合股骨，且胫骨部件的尺寸被定得明显不同以配合胫骨，并且膝假体的部件被最佳地匹配以避免对关节性能采取折中办法。
膝假体***100的尺寸明显不同的股骨和胫骨部件的一个特征是每个部件与所述部件将要连接于其上的特定尺寸的骨骼的相称性。通常，部件的尺寸比例改变，但形状不变。例如，股骨部件可具有尺寸按比例确定的髁间距离，使得大的股骨部件的髁间距离按比例地大于小的股骨部件的髁间距离。相似地，大的胫骨部件可具有与小的胫骨部件相比在比例上更宽和更深的后缺口。
图1是交叉韧带保留型固定支承膝假体110的透视图，其也被称作固定CR假体110，其包括CR股骨部件20（图10）、固定CR***件50（图11）和固定胫骨部件70（图12）。固定CR假体110可与在图1中示出的Hazebrouck的膝假体相同或相似。Hazebrouck公开了多种尺寸明显不同的***件（或支承件）中的任一个可固定到多种尺寸明显不同的胫骨部件（或托盘）中的任一个。因此，可以针对每个股骨部件的尺寸改善***件的关节连接表面的几何形状和其它特征。这种互换能力也允许在设计一系列股骨部件时更少地增加尺寸。CR股骨部件20包括内髁24和外髁26，这二者在固定CR支承件50的上表面56上关节连接。固定胫骨部件70的前支墩(buttress)75和后支墩76将CR***件50固定地保持到固定胫骨部件70上，使得CR***件50的下表面54置于固定胫骨部件70的平台72上。固定胫骨部件70还包括***到通过外科手术预备的近端胫骨中的柄部74。
图5是后稳定型固定支承膝假体120，其也称固定PS假体120，其包括PS股骨部件10、固定PS***件30和固定胫骨部件70。PS股骨部件10可与在图1中示出的Wyss的股骨部件相同或相似。PS股骨部件10包括内髁14和外髁16，这二者在固定PS***件30的上表面36上关节连接。PS股骨部件10还包括位于内髁14和外髁16之间的盒状物32。盒状物32包住可操作地与固定PS***物30的棘突32接合的后凸轮和前凸轮（二者均不可见），如Wyss所述。固定胫骨部件70的前支墩75和后支墩776可保持PS***件30，使得PS***件30的下表面34坐落在固定胫骨部件70的平台72上。
图9是交叉韧带保留型活动支承膝假体130的透视图，其也称活动CR假体130，其包括CR股骨部件20（前文已参照图2进行了描述）、活动CR支承***件60和活动胫骨部件80。CR股骨部件20的内髁24和外髁26在活动CR***件60的上表面66上关节连接。活动CR***件60的下表面64相对于活动胫骨部件80的平台82关节连接。柱68从下表面64向下延伸并可旋转地***活动胫骨部件80的中空柄部84。
图13是后稳定型活动支承膝假体140，其也称活动PS假体140，其包括PS股骨部件10（前文已参照图6进行了描述）、活动PS***件40和活动胫骨部件80（前文已参照图12进行了描述）。活动PS***件40包括可与图7所示的固定PS***件30的上表面36和棘突32相同的上表面46和棘突42。活动PS***件40还包括可与图3所示的固定CR***件50的下表面54相同的下表面34。
图17是表示包括图1、图5、图9和图13中的各膝假体的一体式膝假体***40的图表。各部件10、20、30、40、50、60、70和80可按照多种尺寸（例如，十种尺寸）设置，以适应患者群体大范围变化的解剖结构。这些部件可如下匹配到一起：
PS股骨部件10的任一尺寸可与固定PS***件30或活动***件40的任一尺寸匹配。
CR股骨部件20的任一尺寸可与固定CR***件50或活动CR***件60的任一尺寸匹配。
固定胫骨部件70的任一尺寸可与固定PS***件30或固定CR***件50的任一尺寸匹配。
活动胫骨部件80的任一尺寸可与活动PS***件40或活动CR***件60的任一尺寸匹配。
另外，各***件30、40、50和60的每种尺寸可以多种厚度提供。
如前所述，患者的解剖结构不仅在尺寸方面有变化，而且在股骨/胫骨的尺寸比例方面有变化。利用TKR手术的历史数据，可确定为全世界群体内的大多数患者所需的尺寸组合。例如，可用尺寸定得显然不同的膝假体适应对于差不多所有患者中的每个患者的股骨和胫骨这二者的配合，实现方式如下：通过将股骨部件与大两种尺寸或小两种尺寸范围内的胫骨部件配对。“尺寸3”的CR股骨部件可与“尺寸1、2、3、4或5”的（固定或活动）胫骨部件中的任一个一起使用，而“尺寸1”的CR股骨部件可与“尺寸1、2或3”的（固定或活动）胫骨部件中的任一个一起使用。相似地，“尺寸5”的固定胫骨部件可与“尺寸3、4、5、6或7”的（CR或PS）固定***件中的任一个一起使用。通过利用膝假体***100，这些配对中的每一对使股骨部件能够与***件最佳地匹配，以保持理想的几何关系。
表1列出了示例性实施例的膝假体***100的部件。表2列出了针对表1列出的各股骨部件提供的股骨部件尺寸。表2还针对每个股骨部件尺寸给出：对于表1中列出的各***件相容的***件尺寸，以及对于表1中列出的各胫骨部件相容的胫骨部件尺寸。

表1和表2中示出的膝假体***100的实施例提供了2176种独特的假体部件组合。在这些组合的每一个中，股骨部件的尺寸被定得明显不同以配合患者的股骨，同时与***件最佳匹配，并且胫骨部件的尺寸被定得明显不同以配合患者的胫骨，同时与***件相容。结果，膝假体***100可让医生不用对世界患者群体中的每个患者在运动性能和植入关节寿命之间进行折中。
如前文指出，髌骨部件也可与膝假体组合地提供以用于植入。髌骨部件可以被提供多种尺寸。适于用在膝假体***100中的髌骨植入物的实例为可得自DePuyOrthopaedics,Inc.(Warsaw,IN)的“P.F.C.Sigma髌骨植入物”。膝假体***100的另一实施例还可包括两种独特类型的髌骨部件，每个类型有五种尺寸，从而允许医生从21,760种独特的部件组合中进行选择。在这些组合的每个中，股骨部件的尺寸被定得明显不同以匹配患者的股骨，同时与***件最佳匹配，并且胫骨部件的尺寸被定得明显不同以配合患者的胫骨，同时与***件相容。
膝假体***100允许医生选择一种用于植入到患者体内的膝假体部件的组合，其中所述部件的尺寸被定得明显不同以配合患者的股骨和胫骨，同时还被最佳匹配，以避免对重建关节的性能采取折中办法。膝假体***100还提供PS股骨部件，既然（固定或活动）PS***件与每个PS股骨部件匹配，所述PS股骨部件的尺寸就按比例确定为适合股骨。膝假体***100还可降低必需的植入部件库存的成本和复杂度，以顾及世界范围的患者群体，这主要是由于部件的可互换性。
如前文阐明，需要这样一种膝假体***，其包括具有不同长度的柄部的活动和固定胫骨部件，但不要求用于预备胫骨的若干个不同的扩孔工具。如图17所示，活动胫骨部件80和固定胫骨部件70可具有用于每种解剖尺寸的大致相似或相同的外尺寸和构造，使得医生能够利用相同的器械按照大致相同的方式预备近端胫骨。这还允许医生甚至在通过外科手术预备好近端胫骨之后植入任一种类型的胫骨部件。
图18、19、20和21示出了膝假体***100的四种代表性尺寸的活动胫骨部件80。例如，膝假体***100可具有十种尺寸的固定胫骨部件70和十种尺寸的活动胫骨部件80，如表2所示。图18是尺寸1的活动胫骨部件150的前视图，其具有尺寸1的平台152、尺寸1的柄部154和在柄部154和平台152之间延伸的一对对置的龙骨151、153。柄部154具有长度为“E”的远端部分156和长度为“A”的近端部分158。
图19是尺寸3的活动胫骨部件160的前视图，其具有尺寸3的平台162、尺寸3的柄部164和一对对置的龙骨161、163。柄部164具有长度同样为“E”的远端部分166和长度为“B”的近端部分168。
图20是尺寸7的活动胫骨部件170的前视图，其具有尺寸7的平台172、尺寸7的柄部174和一对对置的龙骨171、173。柄部174具有长度同样为“E”的远端部分176和长度为“C”的近端部分178。
图21是尺寸9的活动胫骨部件180的前视图，其具有尺寸9的平台182、尺寸9的柄部184和一对对置的龙骨181、182。柄部184具有长度同样为“E”的远端部分186和长度为“D”的近端部分188。
如图18、19、20和21所示，长度“D”大于长度“C”，长度“C”大于长度“B”，长度“B”大于长度“A”。通常，增加的柄部长度对应于柄部近端部分的增加长度，而远端部分的长度保持不变。
远端部分156、166、176和186还可具有相同的大致锥形的形状。近端部分158、168、178和188可具有大致相同的截头圆锥形形状，并且主要在长度上发生变化。龙骨151、153、161、163、171、173、181、183可具有大致相似的构造和取向。本领域技术人员应当清楚，医生可使用相同的扩孔工具来在近端胫骨形成期望深度的腔，以接纳各种尺寸的柄部154、164、174和184中的任一种。因为多种尺寸明显不同的固定胫骨部件中每个的外部尺寸和构造可与所述多种尺寸明显不同的活动胫骨部件中对应的一个大致相似或相同，所以对于给定尺寸的任一所述固定或活动胫骨部件来说近端胫骨的外科手术预备可相同，并且对于固定和活动胫骨部件这二者的所有尺寸来说，需要的器械可以相同。
如前文阐明，还希望全膝置换***包括具有通用的平台轮廓或“占有面积”的活动和固定胫骨部件，所述平台轮廓或“占有面积”对于胫骨平台的覆盖范围、与周围组织的交互作用、运动性能和其它因素进行优化。图22A、22B、23A、23B、24A、24B、25A和25B示出了膝假体***100的四种代表性尺寸的固定和活动胫骨部件的俯视（平面）图。如前所述，膝假体部件100可具有十种尺寸的固定胫骨部件70和十种尺寸的活动胫骨部件80，如表2所示。
图22A示出了尺寸1的活动胫骨部件150，其具有与图22B所示的尺寸1的固定胫骨部件250的平台252的“占有面积”或轮廓相似的“占有面积”或轮廓的平台152。
图23A示出了尺寸3的活动胫骨部件160，其具有与图23B所示的尺寸1的固定胫骨部件260的平台262的轮廓相似的轮廓的平台162。
图24A示出了尺寸7的活动胫骨部件170，其具有与图24B所示的尺寸1的固定胫骨部件270的平台272的轮廓相似的轮廓的平台172。
图25A示出了尺寸9的活动胫骨部件180，其具有与图25B所示的尺寸1的固定胫骨部件280的平台282的轮廓相似的轮廓的平台182。
对于每种尺寸的胫骨部件，针对用于特定解剖尺寸的活动和固定胫骨部件这二者来说，平台轮廓（从顶部沿着柄部轴线的方向看）是相同的。当在活动和固定假体之间选择时，不需要改变胫骨部件尺寸来获得相同的胫骨平台覆盖范围。通用平台形状的另一优点是可在两种胫骨部件的制造过程中使用相同的造模工具或所述工具的一部分，使得部件成本降低。
以上说明并描述了各种实施例和实例。但是，本领域普通技术人员可修改本文描述的方法和装置而不脱离本发明的总体概念。例如，附图的具体材料、尺寸和比例应当被理解为非限制性实例。因此，以下权利要求的范围不应被理解为受限于说明书和附图中显示和描述的结构、材料或行为的细节。
