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 driver assembly further has a wire driver extending therefrom, 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.

A wedge has an outer perimeter and includes a top surface extending generally in a first plane and having a top osteointegration surface disposed thereon. A bottom surface extends in a second plane that extends obliquely with respect to the first plane. The first plane intersects the second plane outside the outer perimeter of the implant and includes a bottom osteointegration surface disposed thereon. A plurality of side surfaces extends between the top surface and the bottom surface and defines the outer perimeter, wherein at least a portion of the plurality of side surfaces is devoid of any osteointegration surface.

A set of glenoid components a first glenoid component of a first type and of a first size and a second glenoid component of a second type and of the first size. The first glenoid component includes a first body including a first joint surface and a first bearing surface disposed oppose the first joint surface. The first joint surface has a first dimension. A first anchor extends from a central region of the first bearing surface. The second glenoid component includes a second body including a second joint surface and a second bearing surface disposed opposite the second joint surface. The second joint surface having a second dimension that is the same as the first dimension. A second anchor extends from a central region of the second bearing surface.

A four-component artificial intervertebral disc may provide six degrees of movement: flexion, extension, lateral bending, axial rotation, axial deflection, and anterior/posterior translation. The disc may include a superior endplate, a superior core, an inferior core, and an inferior endplate. The superior endplate may include a concave mating surface, and the inferior endplate may include a spherical mating surface. The superior endplate may roll across the superior core to provide flexion, extension, and lateral bending. The superior endplate may twist or rotate atop the superior core to provide axial rotation, and the superior endplate may slide over the superior core to provide anterior/posterior translation. The superior core may be connected to the inferior core, and the inferior core may be connected to the inferior endplate. The inferior core may be made from a flexible material that may enable the artificial disc to expand or compress vertically.

Disclosed is a medical device having a substrate having an exposed surface and a texture over at least part of the exposed surface. The texture includes a plurality of nanofeatures that inhibit bacterial adhesion on the surface and that also inhibit bacterial growth on the surface and have a size range between about 0.01 nanometers and about 1,000 nanometers. The texture can include a plurality of nanofeatures applied thereto such that the texture has a first particle size at a first location, a second particle size at a second location, and a gradient of particle size from the first particle size to the second particle size between the first location and the second location.

A bone plate system may include a bone plate having a bone-facing side, an obverse side displaced from the bone-facing side by a thickness of the bone plate, a first end, and second end displaced from the first end along a longitudinal length of the bone plate. The bone plate may have a first fastener hole extending through the bone plate between the bone-facing side and the obverse side, a second fastener hole extending through the bone plate between the bone-facing side and the obverse side, and a plug extending outwardly from the bone-facing side. The plug may have a cross-sectional shape, perpendicular to the thickness, that is elongated along the longitudinal length.

Disclosed is a medical device having a first implant portion having a proximal end, a second implant portion connected to the first implant portion, the second implant portion having a distal end, and a driver assembly removably connected to the distal end, the driver assembly comprising a drill connected to the distal end at a connection.

A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. An access cannula may be introduced over the first dilator tube. A drill may be inserted through the access cannula and used to perform a foraminoplasty, Surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.

A disc replacement device including a first body member with a convex articulation surface and a second body member with a concave articulation surface is disclosed. When operably positioned, the convex articulation surface engages the concave articulation surface to provide for movement therebetween. The disc replacement device also includes a first opening in the first body member and a second opening in the second body member, wherein the openings are angled and extends from the front aspects of the body members through the external surfaces. The disc replacement device further includes at least two bone fasteners for insertion into the first and second openings to secure the disc replacement device to a first and second vertebra. An interbody motion device and fusion implant, as well as a surgical method for implantation are also disclosed.
