An intervertebral implant is disclosed. The implant can be made of Titanium or alloys thereof. A kit of intervertebral implants can be included having different lordotic profiles or having no lordotic profile. The intervertebral implants of the kit have endplates with thicknesses suitable to prevent the titanium endplates from being too stiff. The intervertebral implants can have apertures that extend through the endplates, but sufficient surface area at the outer surfaces of the endplates to avoid subsidence into the respective vertebral body.

An interbody spacer for a spine includes a housing having a plurality of clearance holes configured to engage bone of the spine. A contact plate including a plurality of apertures is positioned a distance away from the housing configured to engage bone of the spine. A plurality of rivets adjoin the housing and the contact plate. A plurality of springs are included with each spring configured to encircle a respective rivet and translate the distance between the housing and contact plate from a minimum distance to a maximum distance.

A prosthetic implant for engagement between first and second vertebrae. The implant includes a first plate configured for attachment to the first vertebrae and defining a first interbody connection member and a second plate configured for attachment to the second vertebrae and defining a second interbody connection member. An interbody component includes a body with a first end defining a first plate connection member configured for connection to the first interbody connection member and a second end defining a second plate connection member configured for connection to the second interbody connection member. A method of inserting the implant is also provided.

Implant inserters and related methods are disclosed herein, e.g., for delivering a fusion cage or other implant to a spinal disc space and for rotating or articulating the implant within the disc space. An exemplary instrument can include an inner member having opposed jaws for grasping the implant and holding the implant during insertion. The inner member can be slidably received within an outer member such that relative axial translation of the inner and outer members is effective to open or close the jaws. The jaws and/or the distal end of the outer member can have a low-profile geometry, which can advantageously facilitate certain surgical procedures. For example, the low-profile geometry can allow for a more medial approach to an intervertebral disc space in which the implant is to be inserted.

A virtual model a planned instrument attachment can be provided to ensure correct selection of a physical instrument attachment. An XR headset controller can generate a shape and a pose of the virtual model of the planned instrument attachment based on predetermined information associated with the planned instrument attachment and based on a pose of an instrument relative to the XR headset. An XR headset can display the virtual model on a see-through display screen of the XR headset that is configured to allow at least a portion of a real-world scene to pass therethrough.

The present disclosure relates to an expandable interbody that includes superior and inferior shells enclosing a control mechanism that includes interlocking proximal and distal cages as well as an adjustment screw that longitudinally translates the distal cage relative to the proximal cage and thereby expands interbody by pushing apart the distal ends of the superior and inferior shells.

A system for treating dysfunctional SI joints that includes a multi-function bone structure prosthesis adapted to be delivered to and inserted into a dysfunctional SI joint via a posterior approach, the multi-function bone structure prosthesis, when disposed in a dysfunctional SI joint, being adapted to (i) stabilize the dysfunctional SI joint, (ii) induce proliferation, and/or growth and/or remodeling and/or regeneration of osseous tissue and, thereby, healing and arthrodesis of the dysfunctional SI joint, (iii) attenuate pain associated with the dysfunctional SI joint via neurostimulation, and (iv) monitor physiological and/or biomechanical parameters associated with the dysfunctional SI joint via one or more sensor systems.

An intervertebral implant frame that is configured to engage a spacer can include a pair of arms that extend longitudinally from a support member such that the arms engage the spacer. The spacer can be made from bone graft, and include a first spacer body made of cortical bone, and a second spacer body made of cancellous bone.

An implant and method for posterior sacroiliac fusion having a plate for placement across the posterior surface of the sacroiliac joint, a transverse pin to slide through the plate and transverse the joint as well as provide an aperture to receive bone graft, and a sacral screw to be inserted through the plate.

A pedicle insulator implant is designed to protect the nerves and surrounding tissue from injury by pedicle screws or other surgical devices and instruments. The implant is configured to shield a fixture, reduce nerve root irritation, and diminish loosening of the fixture, when the fixture is implanted into the void of a target site. The implant includes features for stabilizing and securing the implant within the void at the target site. For example, in one embodiment, the implant includes one or more ridges and one or more teeth sections that stabilize the implant against rotational and extractive forces that could disturb the implant.
