A talar implant includes a post projecting from a superior surface of the plate and includes at least one threaded hole. A talar dome having an inferior surface is configured to face the plate and an opening in the inferior surface is shaped to receive the post. The talar dome includes at least one through hole having a threaded surface and a groove. The groove has a larger outer diameter than the threaded surface. At least one fastener is configured to engage the threaded hole of the post and the threaded surface of the through hole. The at least one fastener has a groove that is aligned with the groove of the through hole when the fastener is inserted in the talar dome and the post. At least one clip is configured to engage the groove of the through hole of the talar dome and the groove of the fastener.

An expandable intervertebral cage includes vertically opposed superior and inferior plates and longitudinally opposed distal and proximal wedges disposed between the plates. The wedges define ramps that engage complimentary ramps of the superior and inferior plates to increase a vertical distance between the plates. An actuator is located between the plates, defines a central, longitudinal axis, and is coupled to the wedges such that, as the actuator rotates about the axis, at least one of the wedges moves longitudinally relative to the other, thereby increasing the vertical separation distance. At least one locking component is insertable within a receptacle at least partially defined by the proximal wedge and is configured to transition from an unlocked configuration, where the actuator is rotatable relative to the proximal wedge, to a locked configuration, where the actuator is rotationally affixed relative to the proximal wedge.

An expandable intervertebral implant is provided for insertion into an intervertebral space defined by adjacent vertebrae. The expandable intervertebral implant includes a pair of outer sleeve portions and an inner core disposed between the outer sleeve portions. Movement of the inner core relative to the outer sleeve portions causes the outers sleeve portions to deflect away from each other, thereby engaging the expandable intervertebral implant with the vertebrae and adjusting the height of the intervertebral space.

Embodiments herein are generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. In some embodiments, these implants and implant trials may be used in conjunction with corpectomy procedures.

An orthopaedic surgical instrument system that includes an orthopaedic surgical instrument adapted to be positioned on a proximal end of a patient's tibia, and a tibial bearing trial assembly, and a tibial evaluation component, and a tibial base trial component configured to be coupled to the orthopaedic surgical instrument. A tibial evaluation component includes a base plate and a generally Y-shaped posterior buttress extending upwardly from a superior surface of the base plate, such that the posterior buttress of the insert component is configured to be received in the opening of the tibial bearing trial assembly to prevent rotation of the tibial bearing trial component relative to the tibial base trial component.

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.

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 central ramp, a first endplate, and a second endplate, the central ramp capable of being moved in a first direction to move the first and second endplates outwardly and into an expanded configuration. The fusion device is capable of being deployed down an endoscopic tube.

A modular acetabular cup assembly includes an acetabular cup, and a liner seated in the cup. The cup includes an end face, an apex opposite the end face, and a central axis extending between the apex and a center point of the end face. The liner includes an articular surface having a center of rotation which defines a pivot point of the acetabular cup assembly. In certain embodiments, the pivot point is laterally offset from the center point such that the end face is located between the pivot point and the apex.
