The present invention is directed to methods and compositions regarding the preparation of an cell concentrate, such as, for example, an osteogenic cell concentrate, from a physiological solution, such as bone marrow aspirate, blood, or a mixture thereof. In specific embodiments, the invention provides methods and compositions utilizing two physiological solution-processing techniques, particularly in a point of care environment, wherein centrifugation is not employed.

Preparation of a cell concentrate from a physiological solution

A porous medical implant and a method of making same is described. The medical implant comprises a porous surface formed by application of pulsed electrical energy ins such a way as to cause a localized heating in the surface of the material comprising portions of the implant. The method comprises a pulsed current sintering technique.

Pulsed current sintering for surfaces of medical implants

A partial rim implant for an acetabulum in a pelvic bone comprises a ridge, a bearing surface, and a fixation surface. The ridge is oriented to replace a labrum. The bearing surface is configured to align with the articulating surface of the acetabulum. The bearing surface extends from the ridge toward the apex of the acetabulum. The fixation surface is configured to fix the implant to a prepared bone surface of the pelvic bone.

The present invention is directed to methods and compositions for manufacturing a bone graft substitute. A powder compaction process is utilized to generate a shaped product comprised of a granulated bone material, such as demineralized bone matrix. In addition, a processing aid is utilized to facilitate compaction of the granulated bone material and for release of the product from the die.

An impactor apparatus and method for assembling modular orthopedic prosthesis parts includes a base member that can be for example an instrument from a tray or an instrument tray lid. The base member defines a plane and provides a plurality of components extending away from the plane. The tray components include a pair of spaced apart supports. An impactor tool can be removably supported upon the supports in a fixed position relative to the base member, preferably generally parallel thereto. The components include an impact driver tool actuator that pivotally attaches to the base member. A pair of prosthesis parts or components are connectable at a taper lock connection defined by respective tapered annular portions of the prosthesis parts. The components and impact driver tool support the prosthesis parts adjacent the base and axial alignment with the impact driver tool, the prosthesis parts being generally positioned in between the pair of spaced apart supports. The impact driver tool provides an actuator for activating the driver to transmit a load to the prosthesis parts for driving the parts together at the taper lock connection. The spaced apart supports of the base hold opposite end portions of the assembly of the prosthesis and impact driver in fixed relation to the base member.
