Abstract:
1. A surgical assembly comprising: a post having a longitudinally extending axis, the post comprising a pole and a retainer; a support for resisting movement of the post in a negative longitudinal direction; a platform offset from the support in a positive longitudinal direction, the platform having an opening through which the post projects, the opening having a throat; wherein the retainer is a sleeve that circumscribes the pole and is longitudinally positionable along the pole so that in the first position the sleeve projects into the opening so that the dimension of the post is a dimension of the retainer, as a result of which the post is rendered incapable of passing through the throat and so that in a second position the sleeve does not project into the opening so that the dimension of the post is a dimension of the pole, as a result of which the post is rendered capable of passing through the throat.
