Abstract: A spinal implant is provided and includes a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, opposed side surfaces that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies. The top and bottom surfaces have a surface roughness between 3-4 ?m. A cavity extends through the top and bottom surfaces defining a surface area that is at least 25% of a surface area of the top surface or the bottom surface. First orifices are defined through the top surface and second orifices are defined through the bottom surface. The second orifices are connected to the first orifices by a plurality of channel.

Abstract: According to one embodiment of the disclosure, an implant includes a body having a surface with a flexible pattern defined by a plurality of material segments including a first material segment and a second material segment. The first material segment abuts the second material segment. Further, the first material segment includes a first non-linear shape extending between a first end and a second end while the second material segment includes a second non-linear shape extending between a first end and a second end. The two material segments are interconnected such that one of the first end and the second end of the first non-linear shape is interconnected with one of the first end and the second end of the second non-linear shape.

Abstract: A spinal interbody implant includes a shaft extending along and rotatable about a central axis. The shaft includes a first threaded region. The implant further includes a first link having a first end with first gear teeth. The first end of the first link is fixed at a first point relative to the central axis such that the first gear teeth engage the first threaded region.

Abstract: A spinal plate bender includes an actuation assembly, a collet, and a head portion. The actuation assembly includes a housing, a lever pivotably coupled to the housing, a linkage pivotably coupled to the lever, and an actuation shaft operatively coupled with the linkage. The lever is transitionable between a neutral position and an actuated position, which imparts axial displacement to the actuation shaft. The collet includes a proximal section, a sleeve section extending distally from the proximal section, and a coupling section extending distally from the sleeve section. The head portion is configured to support a spinal plate. The head portion includes an anvil portion coupled to a distal end portion of the actuation shaft. The anvil portion is configured to engage a spinal plate to cause bending of a spinal plate supported in the head portion.

Abstract: An interbody spacer is provided including a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, opposed side surfaces that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies.
