Abstract: A bone suture assembly including a flexible generally cylindrical sleeve, a plurality of lengths of suture extending through the generally cylindrical sleeve, and at least one sleeve securing thread associated with the generally cylindrical sleeve. A bone suture retaining method including engaging a suture with a bone engaging sleeve, inserting the suture and the bone engaging sleeve engaged thereby into a transosseous tunnel formed into a bone by pulling the bone engaging sleeve into the transosseous tunnel and retaining the suture and the bone engaging sleeve in the transosseous tunnel by virtue of the bone engaging sleeve being unable to fit through an aperture in the bone.

Abstract: The invention comprises flat, porous, bioabsorbable implants that are conducive to tissue ingrowth at spinal implantation site, and once absorbed, leave behind a functional ligamentous structure. A preferred material is small intestinal submucosa. Also disclosed are anchoring devices for attaching said implants to the vertebral bodies.

Abstract: Disclosed are cement products, methods of forming cement using the cement product, and methods of using the cement product in orthopedic and dental applications. Generally, the disclosed cement product includes a first component comprising a polymerizable resin comprising ethylenic unsaturated double bond, a second component comprising a compound comprising more than one type of amine selected from the group consisting of primary amines, secondary amines, tertiary amines and quaternary amines, and, optionally, the cement product includes a bioactive component to promote bone formation.

Abstract: A cementless femoral hip stem component. The hip stem component includes an elongate stem, a proximal body, and a collar disposed on the proximal body and extending outward therefrom in a sideways direction to form a ledge. The proximal body defines at least a majority of a frustoconical shape. The ledge formed by the collar includes a tapered undersurface, beneath which extends the proximal body. The tapered undersurface of the ledge and the proximal body extend in different directions and thereby cooperatively define a double-flared contact surface configured to enable subsidable engagement of said double-flared contact surface with the femur at two different rates of subsidence within the femur. An abrupt, male corner is formed by the stem and the proximal body and is sufficiently abrupt to provide enhanced bone ingrowth stimulation.

Abstract: A cementless femoral hip stem component includes an elongate stem having opposing distal and proximal sections. The proximal section includes a conical stem surface which terminates in a proximal end. A collar having a conical undersurface extends laterally outward from the proximal end of the stem. The proximal conical stem portion and the conical undersurface of the collar cooperatively define a unitary double-cone contact surface to allow the collar to subsidably engage with external cortical bone in tandem with the proximal conical stem subsidably engaging with the internal femoral canal.

Abstract: A ball and socket prosthetic joint device. A plurality of curved rigid segments are embedded within and extend out of a polymeric cushion to form a discontinuous hemispherical bearing surface for slidable engagement with a continuous hemispherical bearing surface.
