摘要： A knee prosthesis includes a femoral component and a stem for implanting in a femur. A modular junction is provided for attaching the stem to the femoral component. The femoral component may include a boss having a slot for receiving the components of the modular junction. A portion of the modular junction may be placed within the slot and the modular junction may be tightened in place on the boss by threading the stem into engagement with a portion of the modular junction. Accordingly, the stem may be connected to the femoral component by a single threaded engagement and the position of the stem may be adjusted to any desired location along the anterior-posterior direction on the femoral component.

摘要： A tibial prosthesis locking system. The system includes a tibial plate and an articular surface component or tibial insert. A proximal side of the tibial plate includes perimeter sidewalls with holding flanges formed thereon, and male retaining projections are formed on interior portions of the proximal tibial plate. A distal side of the articular surface component is designed to interlock with the holding flanges and retaining projections formed on the tibial plate. The male retaining projections and the holding flanges cooperatively engage with the articular surface component to provide it with resistance to movement in an anterior-posterior direction, a medial lateral direction, a rotational direction, and a vertical direction.

摘要： A driver including a handle, lever, swivel cap, shaft, and a tip mechanically connected to the lever configured to engage a screw. Engaging the lever causes the tip to either compress or expand so as to lock the screw to the driver. According to one exemplary embodiment, the cap can be translated releasing the lever, thereby releasing the screw from the tip. According to one embodiment, the cap is a swivel cap allowing for jeweler style use. Advantages of the present system and method, according to various embodiments, include a tip compressing a feature that is within an outer diameter of the screw allowing a driver, or a portion thereof, to have a maximum diameter equal to or smaller than the maximum diameter of a screw.

摘要： A pedicle screw and rod assembly is provided which has a low profile in the final position. The pedicle screw includes a screw having a threaded portion and a head portion. A tulip body is positioned on the head portion of the screw. A tulip saddle is coupled to the tulip body and positioned to retain the tulip assembly on the pedicle screw. Wedge members are inserted in between the tulip body and the tulip saddle, causing the saddle to compress and thereby retain a rod within the tulip assembly. Colored wedge members alert a surgeon as to whether the system is in a locked or unlocked state. The top of the tulip assembly is approximately equal in height to, or lower than the rod itself. This provides a low profile pedicle screw and rod assembly since the rod itself will be the uppermost member of the completed assembly.
