A device for treating a bone includes (a) an elongate body sized and shaped for insertion into a bone and extending longitudinally from a proximal end to a distal end, the elongate body including a channel extending therethrough and a coating along an outer surface thereof, the coating adapted to absorb a selected frequency of light such that, when the selected frequency of light is applied thereto, portions of the coating melt to form a mass； and (b) a first anchor member slidably mountable over the elongate body and movable therealong from a first position at the proximal end of the elongate body to a second position adjacent a bone into which the elongate body has been inserted to cooperate with the mass to fix the elongate body to the bone.
