摘要：
A radial head trial device for replacement of a proximal radial head includes a stem component having a center longitudinal axis extending between a proximal end and a distal end, a head component axially and removably attachable to the stem component, wherein the head component is interchangeable with a selection of other head components each axially and removably attachable to the stem component, an anti-rotation feature, and a recess, wherein the anti-rotation feature is structured to be received in the recess to prohibit rotation of the head component relative to the stem component.
