1. An orthopedic trial implant assembly comprising:
at least one radial trial implant including:
a head body that defines a proximal head body surface and a distal head body surface opposite the proximal head body surface substantially along a longitudinal direction, and the head body has a head body height that extends from the proximal head body surface to the distal head body surface along the longitudinal direction; and
a stem that extends from the head body along a distal direction that is substantially defined by the longitudinal direction; and
at least one spacer that is configured to removably attach to the radial trial implant along a direction substantially perpendicular to the longitudinal direction so as to define a composite head including the head body and a spacer head of the spacer, wherein the composite head defines a proximal composite head surface and a distal composite head surface opposite the proximal composite head surface along the longitudinal direction, and the composite head defines a composite head height from the proximal composite head surface to the distal composite head surface,
wherein one of the proximal composite head surface and the distal composite head surface is defined by the head body, and the other of the proximal composite head surface and the distal composite head surface is defined by the spacer head,
wherein the composite head height is greater than the head body height,
wherein the at least one spacer comprises an attachment member that extends from the spacer head and is configured to be removably received by the head body so as to removably attach the at least one spacer to the at least one radial trial implant, and
wherein the distal head body surface defines a plurality of cutting teeth configured to planarize the radius as the head body is rotated about its central axis that is oriented along the longitudinal direction.
