摘要： Knee prosthesis includes a femoral component adapted to fit on a distal end of the femur and a tibial insert component. The femoral component includes a measured anterior/posterior dimension defined by the posterior condyle surface and the interior surface of the anterior flange and a distal peg provided on a distal bone facing surface of each of the lateral and medial condylar structures, wherein the distal pegs are positioned at a midpoint of the measured anterior/posterior dimension. The implant system provides two distinct sizing segments and the tibial insert has a medial tibial aspect ratio of 0.74 and a lateral tibial aspect ratio of 0.65 to 0.68 for all sizes.

摘要： A femoral caliper having one or more anatomical referencing members for placement against portions of the femur, such as the anterior cortex and posterior portion of the femoral condyles, to measure the femur for sizing of the femoral component. A reference mark positioning guide of the femoral caliper is connected to the anatomical referencing member and is capable of guiding placement of a reference mark on the femur that facilitates positioning of the femoral component. The femoral caliper includes an adjustment mechanism capable of displacing the reference mark positioning guide relative to the anatomical referencing member. This allows adjustment of the position of the reference mark (and hence the femoral component) on the femur to account for the up or down sizing of the femoral component. Preferably, the adjustment mechanism adjusts the reference mark positioning guide in the anterior-posterior direction to allow balancing of the tightness or laxity of the selected component.
摘要翻译： 股骨钳具有一个或多个解剖学参考构件，用于放置在股骨部分上，例如股骨髁的前皮质和后部，以测量股骨以确定股骨组件的尺寸。 股骨钳的参考标记定位引导件连接到解剖参考构件，并且能够引导在股骨上引导参考标记的位置，这有利于股骨部件的定位。 股骨钳包括能够相对于解剖学参考构件移动参考标记定位引导件的调节机构。 这允许调整股骨上的参考标记（并且因此股骨部件）的位置以解释股骨部件的上下调整大小。 优选地，调节机构在前后方向上调整参考标记定位导向件，以允许所选择的部件的紧密度或松弛度平衡。

摘要： A knee prosthesis including a tibial component for mounting to the proximal end of a tibia, and a femoral component for mounting to the distal end of a femur. At least the face surface of the medial condylar portion of the femoral component may be preferably substantially congruent with the face surface of a medial cavity in the upper surface of the tibial component so that substantially complete surface-to-surface contact between the face surface of the medial cavity in the upper surface of the tibial component and the face surface of the medial condylar portion of the femoral component is provided throughout a significant portion of the range of flexion of the knee joint. The tibial component may include a base member, an articular bearing member movably positioned on the upper surface of the base member, and structure for restricting the movement of the lateral portion of the articular bearing member relative to the base member to allow a swinging motion thereof relative to the medial portion of the articular bearing member.

摘要： Both a bone fixation device and a method for retrofitting this device in a conventional hollow, intramedullary nail are disclosed herein. The bone fixation device of the invention generally comprises at least one blade member having a top portion registrable with a blade slot provided in the body of the nail, and a bottom surface including a rail slot, as well as at least one wedge member having an inclined top surface for transmitting a blade extending force to the bottom surface of the blade member, as well as a rail which is slidably engageable with the blade member slot. The blade slot and wedge rail interlock to provide a positive retracting force on the blade when it is desired to remove the nail from a bone. Additionally, the wedge member includes a key which interlocks with the longitudinal slot which extends along the longitudinal axis of a conventional Kuntscher intramedullary nail in order to facilitate angular alignment of the blade member with the blade receiving slot in the nail.
