An expandable implant includes a base member including a top surface, a first end, and a second end, and defining a central cavity positioned between the first end and the second end; an adjustable member including a top surface and at least one control channel, wherein the adjustable member is adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position; a control shaft rotatable received by the base member, wherein rotation of the control shaft cause relative movement of the adjustable member relative to the base member; and at least one control member received on the control shaft and by the control channel, wherein rotation of the control shaft causes the control member to translate along the control shaft and along the control channel.

A spinal facet fusion implant comprising: an elongated body having a distal end, a proximal end and a longitudinal axis extending between the distal end and the proximal end, the elongated body being characterized by a superior body surface and an inferior body surface; a superior stabilizer extending outwardly from the superior body surface, the superior stabilizer being characterized by a superior stabilizer surface; and an inferior stabilizer extending outwardly from the inferior body surface, the inferior stabilizer being characterized by an inferior stabilizer surface; wherein (i) the superior body surface and the inferior body surface are tapered relative to one another, and/or (ii) the superior stabilizer surface and the inferior stabilizer surface are tapered relative to one another.

A kit for use in performing joint arthroplasty on a head of a long bone is disclosed. The kit includes: a first implant including a first implant articulating surface and an opposed first implant mounting surface having a first implant location feature; and an instrument for preparing a cavity in the head of the long bone. The instrument includes a body and a punch extending from the body. The punch includes a portion thereof having a shape similar to the first implant location surface of the implant. A method for providing joint arthroplasty is also disclosed.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

Implant assemblies, systems, and methods for stabilizing a joint between a superior vertebra and an inferior vertebra may include a plate member coupled to an interbody spacer with at least one fastener that extends superiorly or inferiorly from the implant assembly to anchor within a vertebral body and stabilize the joint. Inserters and methods of insertion may also be included to facilitate fixation of various implant assemblies within the intervertebral space of the joint between the superior vertebra and the inferior vertebra.

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.

An expandable interbody spacer (10) is provided that includes a pair of oppositely facing endplate components (20, 40) and an interior component that includes one or more vertically extending stacks of arranged C-clip members (70) radially surrounding one or more bosses (30) protruding interiorly from one of the endplates, wherein the size and configuration of the bosses and the C-clip members are designed to allow the incremental expansion of expandable interbody spacer.

A spinal implant includes a first member having a wall that defines an axial cavity. A second member extends between a first end and a second end and defines a longitudinal axis. The second member is configured for disposal with the axial cavity and translation relative to the first member. A third member has an outer surface engageable with tissue and an inner surface disposed to dynamically engage the first end in response to the engagement of the outer surface with the tissue. Systems and methods are disclosed.

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine and methods for inserting said discs. The intervertebral prosthetic discs are provided with connections for facilitating implantation and removal and features which enhance primary and secondary stability over time.

A glenoid implant is provided and may include a body portion and a stem portion. The stem portion may extend from the body portion along a longitudinal axis. The body portion may include an articular side and a bone-engaging side opposite the articular side. At least a portion of the bone-engaging side may be disposed at a non-parallel angle relative to at least a peripheral edge of the articulation side.
