摘要： An orthopedic prosthesis includes a tibial implant and a tibial insert. The tibial implant includes an upper surface, a medial side, a lateral side and a first locking structure provided on the upper surface where the medial side and the lateral side of the tibial implant are defined by a medial-lateral midline. The tibial insert includes a second locking structure provided on its bottom surface. The first and second locking structures are configured for engaging each other along an engagement direction vector when the tibial insert is inserted into the tibial base towards the posterior side. The engagement direction vector is angled away from the medial-lateral midline of the tibial implant towards the medial side of the tibial implant by a predetermine angle.

摘要： A method of minimally invasive unicompartmental knee replacement includes accessing a knee through a minimal incision, forming a planar surface along a tibial plateau of the knee, forming a planar posterior surface along a posterior aspect of the corresponding femoral condyle, resurfacing a distal aspect of the femoral condyle to form a resurfaced area having a curved portion, implanting a prosthetic tibial component on the planar surface along the tibial plateau and implanting a prosthetic femoral component on the prepared surface of the femoral condyle formed by the planar posterior surface and the resurfaced area. The curved portion of the resurfaced area has an anterior-posterior curvature corresponding to a fixation surface of the prosthetic femoral component. Prior to implantation, the femur and tibia are prepared to receive fixation structure of the femoral and tibial components.

摘要： An assembly used in osteosynthesis comprising a delivery instrument in combination with an implant wherein the delivery instrument releasably holds the implant in a first configuration prior to attachment of the implant to bone. The delivery instrument allows the implant to be affixed to bone before the implant is released from the instrument. And the instrument may comprise guide means for drills, depth gauges, screws, pins, pegs, blades and or drivers which are used or implanted when the implant is releasably attached to the instrument. After the implant is affixed to bone and released from the delivery instrument, the implant assumes at least a second configuration which provides compression and or distraction and or control of spatial orientation.

摘要： A washer for use with a bone screw in the reduction and fixation of bone fragments includes a frusto-conical body having a leading end, a trailing end, an exterior surface and an interior surface. A central bore defined by the interior surface for insertion of a bone screw extends longitudinally through the washer. The interior surface is tapered resulting in the central bore's diameter being larger at the trailing end than at the leading end. The washer, when used in combination with a compression bone screw, improves seating of the bone screw head in the bone and results in enhanced compression.

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： Instrumentation for surgically resurfacing a femoral condyle to receive a prosthetic femoral component in minimally invasive unicompartmental knee replacement surgery. The instrumentation includes a resurfacing guide for attachment to a femur and a rail member externally delineating an area of a femoral condyle of the femur that is to be surgically resurfaced to receive a prosthetic femoral component. The resurfacing guide has an abutment wall. The instrumentation includes a resurfacing instrument having a tissue removing surface for removing anatomical tissue from the delineated area of the femoral condyle, the tissue removing surface being movable along the delineated area to remove anatomical tissue therefrom. The resurfacing instrument has a engagement wall for contacting the abutment wall to limit the depth to which anatomical tissue is removed.

摘要： A surgical device for pressing and retaining adjacent bones against one another comprising a compression brace and separate fasteners. The compression brace has at least two fastener retaining portions. Each fastener retaining portion has a fastener hole therethrough for receiving a fastener, such as a screw or pin. A pair of bridge members are positioned between the fastener retaining portions, and are spaced apart from one another to form a compression opening. The compression bracket can include a plurality of fastener retaining portions and a plurality of compression openings. In some embodiments, the fasteners are maintained in a substantially fixed relation with the fastener retaining portion. The brace is installed on adjacent bones such that a fastener engages each bone. The compression opening is spread apart to draw the fasteners toward one another, and thereby compress the adjacent bones together.
