Abstract: An engineered regenerative biostructure (erb) for implantation into a human body as a bone substitute, which includes an internal microstructure, mesostructure and/or macrostructure to provide improved bone in-growth, and methods for making the erb. Under one aspect of the invention, the biostructure has resorbable and nonresorbable regions. Under another aspect of the invention, the biostructure is constructed of hydroxyapatite, tricalcium phosphate and/or demineralized bone. Under yet another aspect of the invention, the porous biostructure is partially or fully infused with a resorbable, nonresorbable or dissolvable material.

Abstract: An equipment includes at least a shoring rod and at least an anchoring assembly of the shoring rod to a vertebra; each anchoring assembly comprises a base integral with a hook which has substantially planar part, extending in a parallel plane, or forming a slight angle, less than 15 degrees, with the base. The base has a hole which runs right through it, having an oblong cross-section, and the anchoring assembly comprises a hook-shaped component whereof the part corresponding to the base of the hook is linked to a threaded rod capable of being engaged in the hole with the possibly of pivoting about an axis and of displacement in the plane, and capable of receiving a screw.

Abstract: The invention relates to a spinal implant consisting of a bone material body which is embodied in a curved manner in its longitudinal direction and is provided with coupling means.

Abstract: A hard head foil cap is provided for foiling hair on an individual, and comprises a head cap provided with a plurality of long narrow slits each having an opening with a width in the range of 1/64? to ¼?. The slits are spaced around the head cap in two or more orientations. Hair shanks may be pulled through the slits for coloring, foiling, highlighting, or bleaching. A hard head foil cap for imparting designs to hair using a head cap with a plurality of long narrow slits spaced around the cap in two or more orientations, the slits configured to form designs to impart the designs in the highlighted hair. A hard head foil cap made by the process of providing an existing, mass manufactured hair cap with a plurality of long narrow slits spaced around the cap in two or more orientations. A method of treating hair.

Abstract: A medical implant device for use in spinal surgery, and more preferably for use in laminoplasty surgery is provided. The implant is a cage-like member having a generally hollow, elongate body with open ends. The implant is formed from a generally hollow, elongate body having four sides: opposed cephalad and caudal sides, and opposed posterior and anterior sides adjacent to the cephalad and caudal sides. The four sides extend along a longitudinal axis, and define an inner lumen extending between opposed first and second open ends.

Abstract: The present invention is an apparatus for cutting allograft bone implants from donor bone. Die sets of standard sizes are installed in a press. Donor bone is then placed in position between the upper and the lower parts of a matched cutting set comprising a hollow cylindrical cutting blade, a mandrel, and a table which establishes a gap around the mandrel which guides the blade. After the bone to be shaped has been properly placed, a shaped cutting blade is driven through the donor bone, producing a precisely shaped allograft implant. The invention provides for rapid change out of blades, rapid cleaning, and easy maintenance.
