Radial head implant apparatuses and methods are provided in accordance with the subject matter disclosed herein wherein a shaft and a head portion can be axially movable within a stem portion. In one embodiment, a radial head implant can include a head portion for articular engagement with a humerus bone, a stem portion for engagement with a radius bone, and a shaft for engagement with the stem portion. The head portion can include an upper surface for engaging the humerus bone. The stem portion can have an axial opening for receiving at least a portion of the shaft, and a collar can be disposed around the stem portion at a proximal end thereof. An upper portion of the shaft can be configured for engaging the head portion, while a lower portion of the shaft can be elongated and cylindrical for axially fitting into and moving within the axial opening of the stem portion. Other embodiments are also disclosed for axial movement for a radial head implant. Various structures are disclosed for locking the shaft in position within the stem portion.
