摘要： An intercondylar notch cutter using a plunge milling bit and bit guide which engages parallel tracks in a trial prosthesis. The intercondylar notch cutter comprises a cutting bit and a guide sleeve. The cutting bit can be thrust into the femur and then translated through the femur cutting a notch without removing the trial prosthesis. The bit is supported by a guide or housing with a guide platform which extends medially and laterally from the guide. Two condyle articulating surfaces on the platform slidingly engage a condyle surface on a trial prosthesis. Along the condyle surfaces on the trial prosthesis are two parallel grooves. Posts on the notch cutter are slidingly received within the grooves. A surgeon first places the trial implant on the femur without cutting an intercondylar notch. The surgeon can proceed immediately to cut an intercondyle notch without removing the femoral trial prosthesis.
摘要翻译：一种使用插入铣头和钻头引导件的髁间切割刀具，其与试验假体中的平行轨道接合。髁间切割器包括切割钻头和引导套筒。切削刀头可以推入股骨，然后通过股骨翻转切口而不移除试验假体。该钻头由具有引导平台的引导件或外壳支撑，导向平台从引导件中间和横向延伸。平台上的两个髁关节表面滑动地接合在假体上的髁表面。沿着试验假体的髁表面是两个平行的凹槽。切口刀具上的刀片滑动地容纳在凹槽内。外科医生首先将试验植入物置于股骨上，而不切割髁间隙。外科医生可以立即进行切割髁间隙，而不需要移除股骨假体。

摘要： A tibial spacer saw guide for guiding the resection of a bony defect of the lateral or medial condyle of the proximal tibia to accommodate a spacer to be implanted beneath a tibial baseplate of a tibial prosthesis. The saw guide includes a plate having a plurality of locating holes corresponding in spacing and location to pins extending from the inferior surface of the tibial baseplate. The plate has medial and lateral guide edges for guiding a sagittal osteotomy where the guide edges are located relative to the locating holes, and thus relative to the pegs of the tibial baseplate. The saw guide also includes an anterior block extending from the plate and having a plurality of slots for guiding a horizontal osteotomy for the spacer of selected depth. The plate rests on an initially resected surface, and thus the horizontal osteotomy for the spacer is located relative to the initial osteotomy surface. The block is repositionable relative to the plate such that the saw guide can be used for both medial and lateral spacers of both the left and right tibias.
摘要翻译：一种用于引导切除近端胫骨的外侧或内侧髁的骨缺损的胫骨间隔锯引导件，以容纳待植入在胫骨假体的胫骨基底下方的间隔件。锯条引导件包括具有多个定位孔的板，该多个定位孔的间隔和位置对应于从胫骨基板的下表面延伸的销。板具有用于引导矢状截骨的内侧和侧向引导边缘，其中引导边缘相对于定位孔定位，并且因此相对于胫骨基板的钉。锯条引导件还包括从板延伸的前部块，并且具有多个槽，用于引导用于选定深度的间隔件的水平截骨。板位于最初切除的表面上，因此用于间隔物的水平截骨相对于初始截骨表面定位。该块可相对于板重新定位，使得锯条引导件可用于左右胫骨的内侧和外侧间隔件。

摘要： A femoral knee prosthesis having a box internal geometry adjacent the femur which has four intersecting planes which extend from the medial side of the prosthesis to the lateral side. Shims of varying thickness can be added which retain the same internal box geometry. The internal geometry of the shims comprises three intersecting planes. Medial and lateral shims are provided. The internal geometry of the shims is translated slightly anteriorly as they increase in thickness. The shims may be added to either condyle independently, with different thickness on each side.

摘要： The pivotally mounted force input lever of a leg extension exerciser machine is connected by a chain, sprocket and cam system to a multi-element weight stack such that leg-driven pivotal motion of the lever may be resisted by a selectively variable portion of the weight stack. A counterbalanced foot engagement structure is pivotally secured to the outer end of the lever, and the lever is rotationally counterbalanced by a counterweight secured to its opposite end. User leg length adjustment of the machine is effected by pivotally adjusting the foot engagement structure relative to the lever, without shifting the center of gravity of the foot engagement structure, to thereby avoid disturbance of the rotational balance of the input lever. A resisted motion range adjustment mechanism is incorporated in the machine and is operative to selectively vary the weight-resisted angular start setting of the lever without altering the angular position relationship between the force input lever and the machine cam. A position gauge is used to continuously provide a visual indication of the angular position of the input lever within its overall motion range.
