摘要： A bearing component 2 for a joint replacement prosthesis comprises a first bearing element 4; a second bearing element 6, and a linking element 8, operatively connecting the first and second bearing elements 4, 6 and permitting relative motion there between. The flexible linking element 8 prevents dislocation of mobile bearings in a total knee replacement prosthesis. The invention also relates to a bridging element which retains the linking element 8 with some play, which acts as a ligament support 2051, and which causes a deflection of the line of action of a ligament 1018. A joint replacement prosthesis is also disclosed comprising a biasing element 1140 or a tensioning element 1220 operatively coupled to the artificial ligament 1018. The biasing element 1140 or tensioning element 1220 may be housed in the stem of a tibia tray 1006.

摘要： A knee prosthesis is provided for use in knee arthroplasty. In one exemplary embodiment, the present invention provides a tibial prosthesis having a tibial baseplate with a fixed medial bearing component and a mobile lateral bearing component. In one exemplary embodiment, the lateral bearing component is secured to the lateral portion of the tibial baseplate utilizing at least one prosthetic ligament. Additionally, in one exemplary embodiment, a stop is provided to limit anterior or posterior movement of the lateral bearing component relative to the tibial baseplate. For example, the stop may be defined by cooperating shoulders formed on the lateral bearing and the tibial baseplate.

In one aspect, disclosed is an intervertebral device (100) for use in a human spine including an anterior end (104); a posterior end (102); and at least four peripheral walls (22,24,26). The peripheral walls (26) define an interior volume surrounding a midline of the device and include a superior wall (22), an inferior wall (24) and a pair of opposing, generally trapezoidal-shaped sidewalls. Each of the trapezoidal-shaped sidewalls (26) includes an internal hinge element (60) that is rotatable from a first configuration to at least a second configuration such that the device is expandable in first dimension. Each of the internal hinge elements includes an axis that is coplanar with the midline of the device.

摘要： An expandable cage for maintain the position of adjacent vertebrae includes a cage top, a cage bottom, and a plurality of shims. The cage top is adapted for contacting a bottom surface of the upper of the adjacent vertebrae, and the cage bottom is adapted for contacting an upper surface of the lower of the adjacent vertebrae. The plurality of shims are adapted for insertion between the cage top and cage bottom to expand the cage. The shims include a proximal end having a bone graft distribution feature configured such that when bone graft material is introduced to the site of the expandable cage, the bone graft material is separated at the bone graft distribution feature and distributed to either side of the cage.

摘要： A prosthetic foot (124) incorporates a foot keel (165) and a calf shank (126) connected to the foot keel to form an ankle joint area of the prosthetic foot. The foot keel has forefoot and hindfoot portions and an upwardly arched midfoot portion extending between the forefoot and midfoot portions. The calf shank includes an anterior facing convexly curved lower portion which is adjustably attached at a portion thereof to the foot keel by way of a releasable fastener arrangement. The upper end of the calf shank is movable longitudinally of the foot keel in response to force loading and unloading the calf shank during use of the prosthetic foot. A device (125) connected between the upper end of the calf shank and the lower portion of the prosthesis can be used to assist posterior movement of the upper end of the calf shank and control anterior movement of the upper end of the calf shank during use of the prosthesis. The device (125) has springs which store energy during force loading with anterior motion of the upper end of the calf shank in gait and which, during force unloading, return the stored energy as kinetic power for adding to the propulsive force on the user's body generated by the prosthesis in gait.

摘要： A prosthetic foot (64) incorporates a foot keel (65) and a calf shank (73) connected to the foot keel to form an ankle joint area (74) of the prosthetic foot. The foot keel has forefoot and hindfoot portions (67, 66) and a relatively long midfoot portion (68) extending between and upwardly arched from the forefoot and midfoot portions. The calf shank includes a downward convexly curved lower end which is attached at a portion thereof to the keel midfoot portion by way of an adjustable fastener arrangement (75). The adjustable fastener arrangement permits adjustment of the alignment of the calf shank and the foot keel with respect to one another in the longitudinal direction of the foot keel for tuning the performance of the prosthetic foot. The upwardly arched midportion of the foot keel, in addition to absorbing energy from vertical loading by expansion, can be formed with a coiled spring (69) which is compressed to absorb and expanded to return vertical load during use of the prosthetic in wide range of activities from walking to running and jumping.
