Adjustable prostheses and related methods provide a wide range of adjustment along or about multiple axes. The prostheses and related methods make possible a straightforward, yet robust way of securing, e.g., a humeral head prosthesis in a desired position and maintaining the prosthesis in the desired position during use.

Adjustable bone prostheses and related methods

An adjustable locking mount system permits rotation about at least one of x, y, and z axes. Methods provide for rotating and rocking the mount to obtain the desired position, fixing the mount in the desired position, and mounting an object onto the mount.

Adjustable locking mount and methods of use

A knee distraction device is provided for use in knee arthroplasty. A mechanism applies to an adjustable distraction force between the tibial surface and a point on the distal femur of the flexed knee. The spatial relationship of tibia and femur is allowed to change by rotation of the femur around an axis between the center of the hip and the intercondylar area of the distal femur. As the distraction force is applied, relative tensions in the medial and lateral ligamentous structures of the knee are equalized by changes in the spatial relationship of the femur and tibia. During maintenance of distraction, the posterior femoral bone cut may be positioned at a predetermined distance from the cut tibial surface. The use of this mechanism facilitates accurate sizing of the flexion gap and optimal positioning of knee arthroplasty.
