摘要： Radial head prostheses and trialing devices. A radial head prosthesis includes a head component and a stem component, and may include an intermediate component. The head component may be offset from the stem component. The head component includes a bearing surface having an axis of rotation, which may be radially and/or angularly offset from the central longitudinal axis of the stem component. A radial head trialing device may include cutting edges for resection of a distal radius. Another trialing device may allow for adjusting the radial offset and/or angular position of a trial head component from a trial stem component.
