    • The invention provides surgical resection instruments, and methods of use, for facilitating accurately cut surfaces for the placement of femoral prosthesis components. The posterior condyles and anterior femoral cortex provide reference points for measurement and cuts of the femur with these instruments. One embodiment of the femoral resection instrument provides for precise anterior cuts of the femur appropriate for one of several sizes of prosthesis components without the need for separate cutting guides. Another embodiment provides for shifting the cutting location of both the posterior and anterior cuts by a portion of the distance between sizes of the prosthesis components while maintaining the reference position relative to the posterior part of the condyles and corresponding intercondylar notch. A third embodiment has an adjustable paddle so that the femoral resection instrument can be adjusted to the correct orientation when the femoral condyles are worn unequally. These various features may be combined, as desired. The invention includes related methods.
    • 本发明提供手术切除仪器和使用方法,以便于准确地切割用于放置股骨假体部件的表面。 后髁和前股骨皮层为这些器械的股骨测量和切割提供参考点。 股骨切除仪器的一个实施例提供适合于几种尺寸的假体部件之一的股骨的精确的前切口,而不需要单独的切割引导件。 另一实施例提供了将前后切口的切割位置移动假体部件的尺寸之间的距离的一部分,同时保持相对于髁的后部和对应的髁间切口的参考位置。 第三实施例具有可调节的桨叶,使得当股骨髁不均匀地穿着时,可以将股骨切除器械调整到正确的方位。 可以根据需要组合这些各种特征。 本发明包括相关方法。

    • An orthotic joint, and the orthosis with which it is used, for the protective treatment of ligamentous injuries or deficiencies, or as a supplement to total joint replacement. The joint includes coacting guide members that are both slidable and pivotal with respect to each other and, when assembled and supported in pairs on opposite sides of a patient's knee, allow freedom of movement of the knee except for those movements that would normally be controlled by the ligament or ligaments requiring protection. An arrangement of straps connect each pair of guide members and are tensioned (and untensioned) in sequence to perform operations in conjunction with the articulating surfaces of the members that would otherwise be demanded from the protected ligament(s). The orthosis includes a system of interfacial elements and suspension elements that engage the upper and lower leg portions and effectively maintain the orthotic joints in proper positions to restrain abnormal knee movements or, in the case of prosthetic joint replacement, to prevent movements that do not conform with the prescribed action of the replaced joint.

    • The present invention is a rotating track cutting guide system that maintains precise alignment of a bone saw with bone tissue. The rotating track cutting guide generally includes a track subassembly and cutting guide subassemblies attachable to the bone that is to be cut. The track subassembly supports an oscillating surgical saw driver. The track subassembly is removably securable to cutting guide subassemblies which are attachable to the desired bone to facilitate a series of controlled cuts. The design of the track subassembly stabilizes the oscillating saw driver and enables it to both rotate in the plane of the saw blade and move linearly along the track.
    • 本发明是一种使骨锯与骨组织精确对准的旋转轨道切割引导系统。 旋转轨道切割引导件通常包括可附接到待切割的骨的轨道子组件和切割引导子组件。 轨道组件支撑摆动手术锯驱动器。 轨道子组件可拆卸地固定到切割导向组件上,该组件可附接到期望的骨头以便于一系列受控切割。 轨道子组件的设计稳定了振动锯驱动器,并使其能够在锯片的平面内旋转并且沿轨道线性移动。

    • An adjustable trial prosthesis or prosthetic component provides a surgeon with the capability of efficiently and accurately examining a joint's functioning without having to remove a trial prosthesis insert and replace it with another sterilized insert. The adjustable trial has a first surface that approximates the top surface of the corresponding permanent prosthesis and a second surface that engages a bone. A distance adjustment mechanism can alter the distance between the first and second surfaces. The distance adjustment mechanism can include a screw oriented generally between the two surfaces or other distance adjustment mechanisms such as a fluid filled bladder. The adjustable trial can include force transducers to provide information on forces within the joint. To assist a surgeon with the alignment of portions of the musculo-skeletal system, a line of strong light is provided. The light source can be a laser or other suitable light source which is combined with appropriate optics. A balancing apparatus can be used to assess relative tensions on peri-articular soft tissue structures. The balance has a support that is adapted for rigid attachment directly or indirectly to a bone.

    • A knee reconstruction apparatus and method provides for controlling and adjusting the point of fixation of a ligament graft, for example a replacement for the anterior cruciate ligament, which permits precisely and repeatably adjusting the length of the ligament graft or graft components with the joint under a prescribed load prior to fixation. A fixture is fixed on the tibia and includes an adjustable clamp that holds a ligament graft anchored or held in the femur. The clamp can be moved for adjusting the length of the ligament graft, or individual segments of a composite ligament graft while the joint is under a prescribed load. The load carried by one or more individual graft components also can be measured prior to fixation to ensure that each of the segments of a composite ligament graft will carry the desired or selected load for a joint under a prescribed load.
