Abstract: Disclosed shoe cover dispensers function in conjunction with a cartridge of pre-stacked shoe covers utilizing an improved loading process, making the process easier and faster for the user. The cartridge can be inserted into the dispenser and then expanded by the dispenser to achieve a stack of expanded shoe covers ready to be automatically released over a shoe when the shoe is placed inside the dispenser.

Abstract: A multi-purpose bone plate system comprises a set of sterile malleable bone plates, an adjustable bending and contouring tower with adjustable angulation and compression slots and a set of bone plates with angulation and compression slots positioned at pre-selected locations to aid three-dimensional shaping of the bone plate. The surgeon inserts the sterile bone plate template to surround the fractured bone and works the template to acquire the physical shape of the fractured bone, inserts the template into the tower to set the adjustable angulation and compression slots of the tower. Now a symmetrical bone plate is inserted into the tower and bent to a shape that replicates the shape of the bone plate. The three-dimensionally shaped bone plate is sterilized and is attached by screws or nails surrounding the fractured bone segment and provides support to fractured bone segments during healing of the bone.

Abstract: A canine femoral stem system provides a set of sizes of stems designed to fit in a reamed femoral bone canal with controlled interference. The canine femoral stems can be implanted using either a cemented or cementless procedures. Cementless stems have a porous coating of sintered beads on the tapered proximal section providing interference with reamed femoral canal causing friction and initial stability. The distal end of the stem has a tapered fit and contacts the lower region of the reamed femoral bone canal due to curvature of the stem providing distal stability. The porous coating encourages bone ingrowth in the cementless system or cement penetration resulting in long term stability. The cementless system uses either cast cobalt chromium stems with 250±50 ?m beads of cobalt chromium or Ti-6Al-4V stem with 250±50 ?m beads of chemically pure titanium.

Abstract: A plurality of canine acetabular cups designed to fit within different sized spherical reamed bone cavities to produce controlled interference without use of cements, screws or nails. Each of the canine acetabular cups, regardless of size, mates with a common femoral head, providing interchangeability. The controlled interference is obtained through use of a multiple curvature Ti—Al—V shell having a porous coating. The interference starts from zero at 50 degrees from the apex of the shell and extends to full interference value at 90 degrees from the apex. The Ti—Al—V shell carries a UHMW polyethylene insert, which is locked by interference, a non-circular post mated with an elongated opening and a circumferential locking groove mated with an interior projection. Initial stability is provided immediately after surgery due to the interference arrangement; long term stability is afforded by bone ingrowth.
