    • An orthopaedic joint prosthesis may include a first component, a bearing component, and a third component. The first component has a base and a keel protruding from the base to extend into a first bone. The keel's longitudinal axis is offset from a geometric center of the base. The base has a first articular surface and the bearing component has a second articular surface shaped to articulate with the first articular surface. A feature unitary with the first component reversibly attaches to the bearing component. The bearing component has a third articular surface shaped to articulate with a fourth articular surface on the third component. A distraction feature of the bearing component is shaped to provide alignment and/or distraction between the first articular surface and the fourth articular surface during insertion of the bearing component into a joint space between the first and second bones.
    • 矫形关节假体可以包括第一部件,支承部件和第三部件。 第一部件具有基部和从基部伸出以延伸到第一骨中的龙骨。 龙骨的纵向轴线偏离基座的几何中心。 基部具有第一关节表面,并且轴承部件具有成形为与第一关节表面铰接的第二关节表面。 与第一部件可逆地连接到轴承部件的单一结构。 轴承部件具有成形为与第三部件上的第四关节表面铰接的第三关节表面。 轴承部件的牵引特征被成形为在将轴承部件插入到第一和第二骨骼之间的关节空间中时在第一关节表面和第四关节表面之间提供对准和/或牵引。

    • A graft ligament strand tensioner includes a frame member for slidingly retaining loops of sutures extending from graft ligament strands. The tensioner further includes a collar portion, and is provided with a handle having a core portion on which the collar portion is disposed for axial movement, and a grip portion. The tensioner still further includes a spherical member connected to the handle and having rounded surfaces facing the collar portion. The collar portion is tiltingly movable on the spherical member rounded surfaces when manipulation of the handle, to pull sutures on the frame member taut, causes the collar portion to engage the spherical member rounded surfaces. The sliding retention of the sutures and the tilting movement of the collar portion provide substantial equalization of tension in the sutures and thereby the graft ligament strands.
    • 移植韧带股张紧器包括用于滑动地保持从移植韧带股延伸的缝合线的框架构件。 张紧器还包括一个套环部分,并且设置有把手,该把手具有一个芯部分,该套环部分设置在该芯部分上以便轴向运动,一个把手部分。 张紧器还包括连接到手柄并具有面向套环部分的圆形表面的球形构件。 当操纵手柄时,套环部分可在球形构件圆形表面上倾斜移动,以拉紧框架构件上的缝合线,使套环部分接合球形构件圆形表面。 缝合线的滑动保持和套环部分的倾斜运动提供缝合线和由此的移植物韧带股线的张力的显着平衡。
