TITANIUM IMPLANT SURFACES FREE FROM ALPHA CASE AND WITH ENHANCED OSTEOINDUCTION

An orthopedic implant having a titanium or titanium alloy body with a plurality of surfaces. The orthopedic implant is produced according to a process comprising the steps of: (a) additively building the orthopedic implant; and then (b) mechanically, chemically, or mechanically and chemically eroding one or more surfaces of the orthopedic implant to (i) remove alpha case from, and (ii) impart an osteoinducting roughness including micro-scale structures and nano-scale structures into, the one or more surfaces.

Compositions and uses of nanoscale diamond particles for artificial joint

A new insight on the lubrication of artificial joint components is presented. Addition of small amounts of nanoscale diamond particles to an artificial joint promotes a substantial improvement in friction and wear behavior of the artificial joint surfaces. Artificial joint implants are made from a variety of materials ranging from metal alloys to polymers. Suitable methods of applying nanoscale diamond particles to an artificial joint include (i) coating an effective amount of nanoscale diamond particles onto the artificial joint prior to implants; (ii) applying a composition to the artificial joint during an artificial joint implanting surgery, wherein said composition comprises a biocompatible carrier fluid and an effective amount of nanoscale diamond particles dispersed in the biocompatible carrier fluid; (iii) injecting the composition for lubricating the artificial joint into the artificial joint.

SMALL JOINT FIXATION

A method of joining adjacent bone includes providing a medical device having a first implant portion, a second implant portion attached to the first implant portion, and a driver assembly having an instrument adapted to form an opening in bone. The driver assembly is integrally connected to and removably attached to the second implant portion at a connection, distal from the first implant portion.

The method further includes inserting the wire driver into a wire driver tool; placing the first implant portion against a first bone structure; inserting the first implant portion into the first bone structure; removing the second implant portion from the driver assembly; using the driver assembly to form an opening in a second bone structure, adjacent to the first bone structure; and inserting the second implant portion into the opening.

Metal oxide nanostructured surfaces

Embodiments of nanostructures comprising metal oxide and methods for forming the nanostructure on surfaces are disclosed. In certain embodiments, the nanostructures can be formed on a substrate made of a nickel titanium alloy, resulting in a nanostructure containing both titanium oxide and nickel oxide. The nanostructure can include a lattice layer disposed on top of a nanotube layer. The distal surface of the lattice layer can have a titanium oxide to nickel oxide ratio of greater than 10:1, or about 17:1, resulting in a nanostructure that promotes human endothelial cell migration and proliferation at the interface between the lattice layer and human cells or tissue. The nanostructure may be formed on the outer surface of an implantable medical device, such a stent or an orthopedic implant (e.g. knee implant, bone screw, or bone staple).
