A system for implanting an inter-body device between adjacent vertebrae comprises an inter-body device having a plurality of cans secured to a flexible bridge and having a relief portion therebetween. An inserter tube and complementary bullnoses are advantageously secured to the vertebrae by an extension arm for securing the assembly precisely in place. A plurality of articulating trial implants are provided to test fit a disc space for the proper sized inter-body device.

This set (J) comprises glenoid components (S1, S2, M1, M2, L1, L2) that each include a body (S1.1, S2.1, M1.1, M2.1, L1.1, L2.1) defining, on two of its opposite faces, respectively, a joint surface (S1.2, S2.2, M1.2, M2.2, L1.2, L2.2), intended to cooperate with a humeral head, and a bearing surface (S1.3, S2.3, M1.3, M2.3, L1.3, L2.3) bearing against the socket of a shoulder blade. In this set, the glenoid components are provided in several different sizes (S, M, L), respectively defined by the dimensions of the joint surface of their body. At least two glenoid components (S1 and S2, M1 and M2, L1 and L2) of which the bearing surfaces (S1.3 and S2.3, M1.3 and M2.3, L1.3 and L2.3) respectively have different dimensional geometries are provided so as to allow the surgeon to improve the durability of the mechanical cooperation between the implanted component and the operated socket.

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 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.

This set comprises glenoid components that each include a body defining, on two of its opposite faces, respectively, a joint surface, intended to cooperate with a humeral head, and a bearing surface bearing against the socket of a shoulder blade. In this set, the glenoid components are provided in several different sizes, respectively defined by the dimensions of the joint surface of their body. At least two glenoid components of which the bearing surfaces respectively have different dimensional geometries are provided so as to allow the surgeon to improve the durability of the mechanical cooperation between the implanted component and the operated socket.

The present invention provides an intervertebral implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine. The implant includes a spacer portion having an inferior and superior surface, wherein the inferior and superior surfaces each have a contact area capable of engaging with anatomy in the treated area, and the inferior and superior surfaces define a through-hole extending through the spacer body. The present invention further provides holes extending from a side portion to the inferior and superior surfaces of the spacer portion and a plate portion rigidly coupled to the spacer portion, wherein the plate portion contains holes for receiving screws. A fastener back out prevention mechanism adapted on the plate to prevent the back out of the fasteners from the holes and to secure the spacer to the plate of the intervertebral implant.

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 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.

An osteotomy implant includes a first surface extending generally in a first plane and a second surface extending generally in a second plane, oblique to the first plane. The first surface has a perimeter having a first linear edge, a first curve edge connected to the first linear edge, a second linear edge connected to the first curved edge, and a second curved edge connected to the second liner edge.

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.
