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.
