The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.

Abstract: Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.

Abstract: An example mixed reality (MR) system includes a first MR device configured to present first medical information and first real-world information to a first user via a first MR presentation; a second MR device configured to provide second medical information and second real-world information to a second user via a second MR presentation; and a third device configured to provide third information to a third user, wherein the third information is based at least in part on the first MR presentation or the second MR presentation.

Abstract: A tissue repair apparatus includes a housing, a rotatable shaft at least partially disposed within the housing, and first and second curved needles coupled to the shaft. The housing defines a gap between a first edge of the housing and a second edge of the housing, the gap adapted to receive tissue. The first and second needles curved needles being articulable within the housing from a delivery position, at which the first and second needles are spaced from the gap, to a deployed position, at which the first and second needles extend through the gap. Actuation of the shaft simultaneously articulates the first and second needles and the first needle enters the gap before the second needle enters the gap.

Abstract: An instrument to insert a humeral anchor includes a handle including a shaft extending from a first end to a second end; a manual grip at the first end configured to rotate the shaft; and a humeral anchor grip at the second end, wherein the handle is configured to actuate the humeral anchor grip between a first configuration to apply a radially outward force to an interior surface of the humeral anchor and a second configuration to separate the humeral anchor grip from the interior surface of the humeral anchor.

Abstract: A method of fixating a prosthesis to a glenoid includes drilling a first hole in a central portion of the glenoid; and inserting a stem of the prosthesis into the first hole until at least one first deformable fin that encircles the stem engages cortical bone and at least one second deformable fin that encircles the stem engages cancellous bone, the prosthesis including a head portion having a first outwardly curved surface and an inwardly curved surface that is sized and configured to engage at least one of a humerus or a humeral component, wherein the stem is formed from a first material and the head portion of the prosthesis is defined from a second material that is different from the first material.

Abstract: A system for implanting an expandable interbody implant into an intervertebral space includes an elongated tool, the distal end of which is removably securable to the implant. The proximal end of the tool has an attachment interface for detachable securement to a plurality of different modules, each of which is adapted to effectuate a different function of the delivery system. The different functions include: grasping the implant delivery tool, providing an impaction surface for driving the advancement of the implant, supplying a graft material into the implant, and actuating the expansion of the implant. One of the modules may include a fluid delivery system for supplying hydraulic fluid to expand the implant. A fluid reservoir of the fluid delivery system may be oriented transverse to the cannula that delivers the fluid to the implant. A grafting block can be used to help pre-pack the implant with graft material.

Abstract: An anchor trajectory guide and methods of use thereof are provided. The guide includes a body that has a medial side. The medial side can be placed over a lateral side of a fixation plate. The anchor trajectory guide also includes a locator and a plurality of guide apertures. The locator is disposed on or through the medial side of the body. The locator can be mated with the fixation plate. The guide apertures are disposed through the body at positions corresponding to define anchor locations and orientations to provide good purchase adjacent to or in cortical bone around a medial side of a humerus.

Abstract: Disclosed herein are patient-specific cutting guides for guiding a surgical instrument for resecting a portion of a glenoid of a patient. The cutting guides include a base portion having a contact surface shaped to substantially match at least a portion of a cavity of the glenoid. The base portion has a guide hole extending therethrough in which the guide hole has an axis coaxial with an axis of rotation. The cutting guides include one or more stabilization members extending outwardly from the base portion and having a contact surface shaped to substantially match an outer surface of a portion of a scapula of the patient. The stabilization members are oriented to take into account the patient's anatomy in orienting and stabilizing the guide with respect to the glenoid. The guide hole of the base portion is for guiding the surgical instrument to create a guide hole in the glenoid.

Abstract: Surgical kit inspection systems and methods are provided for inspecting surgical kits having parts of different types. The surgical kit inspection system comprises a vision unit including a first camera unit and a second camera unit to capture images of parts of a first type and a second type in each kit and to capture images of loose parts from each kit that are placed on a light surface. A robot supports the vision unit to move the first and second camera units relative to the parts in each surgical kit. One or more controllers obtain unique inspection instructions for each of the surgical kits to control inspection of each of the surgical kits and control movement of the robot and the vision unit accordingly to provide output indicating inspection results for each of the surgical kits.
