A facet joint replacement system includes a facet joint replacement device including an enclosing body and an articulating body. The enclosing body includes an interior surface defining an inner cavity of the enclosing body. The interior surface includes a first articulating surface and a projection extending inwardly relative to a surrounding area of the interior surface. The articulating body is positioned within the inner cavity of the enclosing body and is configured to move within the enclosing body. The articulating body includes a second articulating surface and a recess extending inwardly relative to a surrounding area of the articulating body and aligned with the projection of the interior surface of the enclosing body so as to allow movement of the projection along the recess of the enclosing body while constraining rotational motion of the articulating body within the enclosing body.

The unibody orthopedic instrument includes an elongated handle, a latching interface outwardly extending relative to the elongated handle and selectively couplable to an orthopedic component, and a hand accessible spring-biased lever arm operable with a hinge coupled to the elongated handle about a pivot. The hinge normally positions the latching interface in a first latched position for locking engagement with the orthopedic component and is otherwise operable by the spring-biased lever arm about the pivot to reposition the latching interface from the normally latched position to an unlatched position for disengagement from the orthopedic component.

A shoulder implant system comprising a glenoid implant; a baseplate comprising an implant facing surface to face the glenoid implant; wherein the glenoid implant comprises at least one fixation element configured to engage with at least one fixation element of the baseplate; wherein the at least one fixation element of the glenoid implant comprises a center post having a distal end; wherein the at least one fixation element of the baseplate comprises a center post receptacle; wherein the baseplate comprises an outer periphery; wherein the implant facing surface of the baseplate comprises a channel which extends from the outer periphery of the baseplate to the center post receptacle of the baseplate; and wherein the channel is configured such that, during an assembly of the glenoid implant and the baseplate, the distal end of the post is movable in the channel from the outer periphery of the baseplate to the center post receptacle of the baseplate.

An expandable interbody spacer for the spine is provided. The interbody spacer includes a housing, a top endplate and a bottom endplate. An actuator is located inside the housing between the top and bottom endplates. A locking screw is configured to drive the actuator and move the endplates between collapsed and expanded configurations. Variations of the expandable spacer are provided in which the endplates move bilaterally outwardly into uniform and parallel expansion along the latitudinal axis, the endplates angulate about a pivot point along a longitudinal axis such that the distal end of the spacer increases in height relative to the proximal end, and the endplates angulate about a pivot along a lateral axis such that the height along one lateral side of the spacer increases in height relative to the other lateral side.

A fusion device includes an actuator including a shaft, a receiver disposed posterior to the actuator and configured to be coupled to the shaft of the actuator, and a first plate and a second plate each slidably coupled to the actuator. The first and second plates are configured to move away from each other when the fusion device transitions from a first state to a second state.

A sacroiliac joint implant system includes a primary implant configured to be received in a sacroiliac joint of a patient and a secondary implant configured to couple with the primary implant. The primary implant includes a body extending from a proximal end to a distal end and a plurality of threads extending from the body. The secondary implant includes a first anchor configured to anchor within a sacrum of the patient and a second anchor configured to anchor within an ilium of the patient.

In some embodiments, a spinal stabilization system may be formed in a patient using quick-connect sleeve assemblies. Each quick-connect sleeve assembly can be coupled to a bone fastener assembly in a fast and intuitive way. In one embodiment, a quick-connect sleeve assembly has a detachable member and a movable member. Both members engage a collar of the bone fastener assembly. In one embodiment, the engagement can be locked via one or more locking features to facilitate screwing a bone fastener of the bone fastener assembly onto a vertebral body in a minimally invasive surgical procedure. Each quick-connect sleeve assembly has a low profile and is particularly shaped for minimally invasive entry.

A spacer member is provided that is configured to be implanted adjacent an anatomical structure. The spacer member defines a curved bore, a first opening in a side wall of the spacer member and a second opening in one of a top wall and a bottom wall of the spacer member. Each of the first opening and the second opening are in fluid communication with the curved bore. A flexible anchoring member is configured to be inserted through the side opening and through the curved bore of the spacer member such that a distal end portion of the flexible anchoring member extends out of the second opening at an angle relative to the one of the top wall and the bottom wall of the spacer member.

A method of ankle replacement includes forming an anterior cut in a bone and forming a stem hole in a distal end of the bone. The stem hole is formed using a plurality of broaches positioned against the distal end of the bone through the anterior cut. A first portion and a second portion of a stem implant are inserted into the stem hole through the anterior cut in the bone. The first portion is coupled to the second portion using a coupling device inserted through the anterior cut in the bone. The stem implant is impacted into the stem hole using an offset impactor.

An intervertebral implant that iterates between collapsed and expanded configurations includes first and second plates spaced from one another along a first direction and defining bone-contacting surfaces facing away from each other along the first direction. An expansion assembly is positioned between the plates with respect to the first direction and includes a first support wedge that supports the first plate and defines a first ramp and a second support wedge that supports the second plate and defines second and third ramps. The expansion assembly includes an expansion wedge defining a fourth ramp. The first, second, third, and fourth ramps are each inclined with respect to a second direction that is substantially perpendicular to the first direction. At least one of the first and second support wedges is slidable along the respective supported first or second plate. The implant includes an actuator configured to apply a drive force to the expansion wedge so as to cause 1) the fourth ramp to ride along the third ramp so as to increase a distance between the bone-contacting surfaces along the first direction, and 2) the second ramp to ride along the first ramp, thereby further increasing the distance, thereby iterating the implant from the collapsed to the expanded configuration.
