A modular prosthesis kit includes a sleeve. The sleeve has a central portion and a fin. At least part of the central portion includes a plurality of adjacent terraces. The fin includes a pair of tapered outer surfaces that are continuous, non-terraced and define a wedge-shape to stabilize the position of the sleeve when implanted. The sleeve may include a single terraced spout or wing with such a fin or may not have any spouts or wings extending out from the central portion. The kit may also include sleeves with two spouts or wings extending out from the central portion.

A modular knee prosthesis system comprises a distal femoral articulation component, a distal augment, a posterior augment and a first connector for securing at least one of the augments to the distal femoral articulation component through a bore in the augment and an opening in the distal femoral articulation component. The distal femoral articulation component has a distal bone-facing surface, a posterior bone-facing surface and an opening. The openings into the bores of the augments are in the medial or lateral side surface of the augment. Both augments can be mounted and removed from the distal femoral articulation component from either the medial or lateral side.

Biomedical implants (e.g., orthopedic implants) with modified surfaces that can enhance a cement bond's strength (e.g., tensile, shear, and/or fatigue) are disclosed, along with methods of manufacturing and using such implants. The implants can exhibit a variety of physical, chemical, or process-derived features which can enhance cement bonding. For instance, the implant surface can exhibit particular roughness values, and/or be substantially free of non native material. Processes for producing such implants can include providing a first roughened implant surface, which can be produced, for example, by particle blasting. A treatment formulation can be applied to the first roughened surface to create a second roughened surface that exhibits enhanced cement bonding properties relative to the first roughened surface. In some instances, the first roughened surface and the second roughened surface can exhibit substantially similar Rvalues. The second roughened surface can exhibit a negative Rvalue.

A preassembled collection of disposable mixing apparatus and constituent components needed for the vacuum mixing and preparation of bone cement and packaged as a single disposable kit is disclosed. The kit includes a contoured storage tray, ampules of liquid cement monomer, packets of powder cement copolymer, a small portable vacuum pump, connecting tubing with a vacuum indicator, a mixing cartridge, a cartridge cap and agitator, an assortment of connectable cement nozzles, and a funnel attachment. The kit can be packaged as a single unit for convenient and efficient use in the sterile environment of an operating room. The disposable telescoping mixing cartridge of the kit employs a telescoping mixing cartridge with a vacuum release mechanism.
