    摘要： A telemetric tibial tray includes a lower plate that defines a plurality of cylindrical transducer cavities having circular load diaphragms. An upper plate is attached to the lower plate through support posts projecting from the load diaphragms. The support posts have a circular cross-section and a diameter of about 5.0 mm. The lower plate further defines wiring channels communicating between the transducer cavities and a central cavity housing the circuit board for the telemetric tray. The wiring channels are arranged at a 45 degree angle relative to the sagittal plane of the knee joint in order to reduce the effects of the wiring channel intersection on the strain sensitivity of the tray. Each transducer cavity includes a radial strain gage array with four pairs of radially aligned strain gages, each pair aligned at a 45 degree angle relative to the sagittal plane of the knee joint. Each pair of strain gages includes an inner gage positioned at the point of maximum positive micro-strain across the diaphragm when loaded, and an outer gage positioned at the point of maximum negative micro-strain, to thereby increase the differential strain measured by the gages and increase the strain sensitivity of the tibial tray.

    摘要翻译： 遥测胫骨托包括限定多个具有圆形负载隔膜的圆柱形换能器腔的下板。 上板通过从负载膜片突出的支撑柱连接到下板。 支撑柱具有圆形横截面和约5.0mm的直径。 下板还限定了在换能器腔之间连通的接线通道和容纳遥测盘的电路板的中心腔。 布线通道相对于膝关节的矢状面布置成45度角，以减少布线通道交点对托盘的应变敏感性的影响。 每个换能器腔包括具有四对径向排列的应变计的径向应变计阵列，每对应变计相对于膝关节的矢状平面以45度角对准。 每对应变计包括一个内部量具，当内部计量器在负载时位于隔膜上的最大正微应变点处，并且外部量具位于最大负微应变点处，从而增加由量规测得的微分应变 并增加胫骨托的应变敏感性。

    摘要： A knee prothesis system which is composed of a femoral component and a series of bolts capable of being attached to the femoral component and extending through the femoral component at different angles. These angles correspond to different valgus angles. The system also includes stems of different lengths and diameters which can be attached to the bolts to provide a system with stems of different and diameter lengths set at different valgus angles.

    摘要： A modular prosthesis includes a component having a superior surface and an inferior surface. An elongate aperture having a major axis and a minor axis is defined in the component and a bolt shank is insertable through the elongate aperture in the component to extend beyond the inferior surface thereof. Means are provided for selectably positioning the bolt at one of a number of selected points along the major axis of the elongate aperture. In an illustrated embodiment, the means for positioning the bolt includes more than one seat for a bolt head about the aperture. In another embodiment, the prosthesis includes an adapter having a first end defining a cavity for receiving the shank of the bolt extending from the inferior surface. The adapter includes teeth on the first end that are engagable with at least one or more teeth near the aperture in the component on its inferior surface to fix the cavity, and thus the bolt, at a selected point along the major axis of the aperture. Exemplary prostheses include femoral and tibial components.
