摘要： A locking mechanism for locking a rod in a screw and rod fixation assembly includes a cap having a sidewall and a locking element extending from at least a portion of the sidewall. Locking mechanism cooperates with a receiver component for a spinal fixation rod to lock the rod in the receiver without requiring application of torque. A method of locking a spinal fixation member in a receiver of a screw fixation assembly includes the steps of placing the spinal fixation member into a channel of a receiver, axially advancing a locking cap into the receiver toward the spinal fixation member without application of any torque, and securing the locking cap in a locked position above the spinal fixation member without application of any torque.

摘要： A spinal stabilization system includes an implant and instrumentation for stabilizing the spine. In one embodiment, the system includes a plate having a side rail and a channel extending adjacent the side rail. A pedicle screw assembly is positioned in the channel in releasable engagement with the side rail. The pedicle screw assembly includes a polyaxial screw seated in a lower housing having a lower locking flange. An upper housing having an upper locking flange secures the plate to the lower housing. The side rail of the plate is releasably engaged between the upper locking flange and the lower locking flange. The upper and lower housings include on-board locking mechanisms for fixing components in the screw assembly. The screw assembly and plate are inserted and oriented by remote manipulation. Minimally invasive techniques for inserting the implant are performed with the instrumentation, and cause minimal disturbance to surrounding tissue.

摘要： A fixation plate system includes a plate with elongated slots, and first and second anchors for attaching the plate to vertebrae. The first and second anchors have different head configurations that are selected by the surgeon to control how settlement occurs at each fused segment. The head of the first fastener is insertable in any of the slots and resists translation. The head of the second fastener is insertable in any of the slots in free sliding engagement to allow translation of the head in that slot. In one method of use, the surgeon selects a segment where settling needs to be limited, and uses the first fastener to fix the plate near the segment and limit settling at that segment. The first and second fasteners have a built-in spring that assists in securing the fasteners in the plate.

摘要： An artificial intervertebral disc includes housing members including spaced inner surfaces facing each other and oppositely facing outer surfaces for engaging spaced apart vertebral surfaces. Bearing surfaces extend from each of the inner surfaces for engaging each other while allowing for low friction and compression resistant movement of the housing members relative to each other while under compression. Load sharing pads are disposed between the inner surfaces and about at least a portion of the bearing surfaces for sharing absorption compressive loads with the bearing surfaces while limiting the relative movement of the housing members.

摘要： A plate holder instrument includes a base and a clamp. The clamp is displaceable relative to the base in a longitudinal direction and forms a plate receiving recess with the base. The clamp is displaceable between a released position to allow a bone plate to be loaded into and removed from the plate receiving recess, and a clamped position to lock a plate in the plate receiving recess. An actuator is displaceable relative to the base in a first direction to move the clamp to the released position and a second direction to move the clamp to the clamped position. The plate holder instrument can be combined with one or more surgical instruments, bone plates, screws, tools, taps, depth gauges, screw drivers and/or other accessories as a kit.

摘要： A transverse coupling for connecting multiple implant extensions includes at least a first sleeve and a second sleeve. The first sleeve defines a first aperture adapted to axially receive a first implant extension through the first aperture. The second sleeve defines a second aperture adapted to axially receive a second implant extension through the second aperture. The transverse coupling also includes a central housing. A first shaft connects the first sleeve to the central housing, and a second shaft connects the second sleeve to the central housing. The central housing includes at least one joint for connecting the central housing to at least one of the first and second shafts in a movable arrangement that allows the shaft(s) to move through one or more degrees of freedom relative to the central housing.

摘要： A vertebral body replacement device includes a first member and a first footplate detachably connectable to the first member, a second member and a second footplate detachably connectable to the second member, and a central member detachably connectable to the first member. The first member is displaceable relative to the second member in response to rotation of the central member relative to the first member to adjust the length of the vertebral body replacement device. The first footplate includes a first surface oriented toward the first member, a second surface oriented away from the first member, and a sidewall extending between the first surface and the second surface. The first surface includes an alignment slot facing the first member. The alignment slot is open through the sidewall of the first footplate and configured to slidingly engage the first member to orient the first footplate relative to the first member.

摘要： A spinal rod persuader, system and method can include an outer tube, an inner tube, and a locking element. A first actuation mechanism can be movable in a linear fashion along a longitudinal axis direction to cause the locking element to move in a linear fashion over the inner tube and to lock the inner tube onto a pedicle screw. A second actuation mechanism can be rotated to cause the outer tube to move in a longitudinal axis direction with respect to the inner tube to push the spinal rod into a final position with respect to the pedicle screw while the pedicle screw is locked to the inner tube. A slot and/or tab structure can be provided in the outer tube such that actuation of the slot/tab will allow disassembly of the inner tube, outer tube and locking element with respect to each other.

摘要： A knee prosthesis having a femoral component with two condyles, an opening disposed between the two condyles, and a tibial component having bearing surfaces to engage and support each of the femoral component condyles. Moving the femoral and tibial components in flexion from about 0° to about 165° causes medial pivot rotation of the femoral component upon the tibial component. Rotation may be caused by interaction between an asymmetrical cam extending between the femoral condyles and a post disposed between the bearing surfaces and extending superior from the tibial component. Rotation may alternatively be caused by asymmetrical medial and lateral condyles which translate posteriorly upon respective medial and lateral bearing surfaces at disparate rates, without a femoral cam, a tibial post, or a post/cam contact surface. Embodiments of the knee prosthesis may be used in cruciate-substituting or cruciate-retaining procedures. Embodiments of the knee prosthesis may also prevent roll forward.
摘要翻译：膝关节假体，其具有具有两个髁的股骨部件，设置在两个髁之间的开口，以及具有用于接合和支撑每个股骨组件髁的支承表面的胫骨部件。将股骨和胫骨部件的屈曲从大约0°移动到大约165°将导致股骨部件在胫骨部件上的内侧枢轴旋转。旋转可以由在股骨髁之间延伸的不对称凸轮与设置在支承表面之间并且从胫骨部件上方延伸的柱之间的相互作用引起。旋转可以由不对称的内侧和外侧髁造成，其在不同的速率下在相应的内侧和侧向支承表面上向后平移，而没有股骨凸轮，胫骨柱或柱/凸轮接触表面。膝假体的实施例可以用于十字交替或十字路口保持程序。膝假体的实施例也可以防止向前滚动。
