1. A trial neck for releasable attachment to a bone canal preparation instrument, the trial neck comprising:
a body portion having a bore for receiving a proximal end of the bone canal preparation instrument;
an elongate neck part comprising a pair of arms extending from the body portion, wherein a partially threaded actuator bore extends through the pair of arms;
a clamping mechanism comprising a live spring formed by the body portion and said pair of arms of the elongate neck part; and
an actuator, for moving the clamping mechanism between a clamping configuration and a non-clamping configuration, wherein the actuator comprises a threaded actuation member extending within the partially threaded actuator bore, and
wherein in the clamping configuration, the pair of arms of the elongate neck part are pinched together to cause an inner wall of the bore to urge against the bone canal preparation instrument to retain the proximal end of the bone canal preparation instrument within the bore.
