A spinal implant comprises an implant body extending between an anterior surface and a posterior surface. The implant body includes a first vertebral engaging surface and a second vertebral engaging surface. The implant body includes an outer surface that defines an oblique surface. A wall is connectable with the implant body and translatable relative to the oblique surface. Systems and methods are disclosed.

A set of surgical components for use in a joint arthroplasty to reconstruct a head of a joint is provided. The set of surgical components can include a head member having a first articulating surface opposite a first fixation surface. The first fixation surface can define a first portion that extends outwardly from the first fixation surface. The set of surgical components can include a base member having a fixation peg with three generally triangular fins and a second fixation surface defined as a recess within a top surface of the fixation peg. The first portion of the head member can be received within the recess of the base member to couple the head member to the base member.

Disclosed is an expandable interbody fusion implant that is configured to have an initial configuration having a first footprint width suitable for being inserted into an intervertebral space and an expanded configuration having a second footprint width that is greater than the first footprint width. The implant may include a first body member and a second body member that is pivotally coupled to the first body member. The implant may be expanded using an inflatable balloon. The implant may be expanded bilaterally such that both body members rotate relative to the other or the implant may be expanded unilaterally such that one of the body members rotates relative to the other.

The disclosure claims a lumbar interbody fusion cage for treating lumbar spondylolisthesis via a lateral approach. The lumbar interbody fusion cage comprises a supporting frame body, wherein upper and lower blades are mounted on the upper and lower end surfaces of the supporting frame body, a distracting component for driving the upper and lower blades to axially distract along a lumbar interbody and an orthotopic moving component for driving the upper and lower blades to move along the lumbar interbody back and forth are mounted in the supporting frame body, the upper and lower blades respectively extend to form lateral lobes, fixing holes through which fixing nails penetrate are formed on the lateral lobes, the fixing nail of the upper lateral lobe penetrates backward from bottom to top in a slanting way to give a certain rear thrust to the slipped lumbar vertebrae and help reduction of the lumbar spondylolisthesis, and the fixing nailing of the lower lateral lobe penetrates forward from top to bottom to give a forward thrust to the lumbar vertebrae and help the reduction of the lumbar spondylolisthesis. The lumbar interbody fusion cage can solve both an intervertebral spacing and dislocation arisen from forward and backward lumbar spondylolisthesis, has easy operation and small pain to patients, and is safer and more reliable.

The embodiments disclosed provide an expandable osseointegration bone fixation apparatus configured to be attached to an affected or fractured bone. The apparatus includes an elongated housing containing a cylindrically shaped intraosseous insert have an expansion mechanism. The insert further includes a set of inwardly angled tapers designed to be attached to a diaphyseal bone where a set of diametrically opposed congruent inserts are configured to incrementally expanded in opposite directions and cause an incremental force against the inside surface of the housing to increase compression to the affected bone.

A medical implant apparatus for total elbow arthroplasty is provided. The apparatus includes: a first rod member comprising a first nut, an eye hook, a first end, and a second end, wherein the first nut is disposed at the first end and the eye hook is disposed at the second end; a second rod member rotatably coupled to the first rod member, the second rod member comprising a first linear portion, a second linear portion, and an arcuate portion disposed between the first linear portion and the second linear portion, the arcuate portion being configured to form a predetermined angle between the first rod member and the second rod member; a positioning nut coupled to the first linear portion of the second rod member; and an aperture disposed in the eye hook.

The embodiments of the present disclosure relate to a spinal implant assembly having features to prevent or minimize fixation elements, such as screws, from being dislodged, or from backing out over time and with use. The spinal implant assembly may comprise an implantable body having first apertures for receiving fixation elements. A plate configured to nest against the posterior portion of the implantable body and comprising one or more second apertures can be provided. These second apertures permit access to the head portions of the fixation elements. One or more locking elements are then passed through the second apertures and engage the head portions of the fixation elements. In addition, the plate may comprise an adjustable arm to allow the plate to be used with implantable bodies of different size.

An expandable fusion device is capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device may include 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.
