Abstract: A holder for supporting a vial containing fluid therein in an inverted inclined position is shown. The holder includes a vertical back member adapted to be fastened to a wall and a planar top support extends from the backplate at a predetermined acute angle relative to a horizontal plane and has a length which is greater than the width of a vial. The planar top support receives and supports the bottom of the vial and produces a clamping force thereagainst. A planar bottom support extends from the vertical backplate at substantially the same acute angle as the planar top support and has a length equal to the distance from the backplate to a line which intersects with a plane which is normal to the end of the planar top support. The planar bottom support has an elongated slot to receive the neck of a vial and extends from the outer edge of the planar bottom support to an aperture extending through the planar bottom support.

Abstract: A prosthesis for the wrist joint and other joints which includes a carpal component having a base for cooperation with a radial component. The base is formed in the shape of a half-toroid, each end of the toroid integrally forming an intra-medullary pin for insertion into the medullary canal of the metacarpals with acrylic cement or equivalent gap-filling medium. The radial component of the prosthesis has a seat which is generally concave for receiving a side of the base of the carpal component. The seat includes a pair of adjacent concave surfaces tapering into cylindrical shafts, the toroidal base located between the shafts. A ridge is formed between the concave surfaces allowing the toroidal base to ride upon the ridge and rotate front to back and/or slide side to side. A tapered, notched stem extends from the seat for insertion into the medullary canal of the radius.
