Abstract: The following relates to patient-specific or patient-matched, customized apparatus for use in surgical procedures, including various interbody procedures. The patient-matched apparatus may be a modular implant, a monolithic implant, and may include an instrument for use in procedures involving a modular or monolithic implant. One or more patient-matched apparatus described herein may be configured for use with a guide, with robotic instrumentation, or with augmented reality system.

Abstract: An implant in the form of a bone screw that meets device tracking requirements set for the in the FDA regulations is provided. The bone screw includes a screw body and a tag body formed as an integral extension of the screw body and is connected to the screw body via a frangible interface bone screw. The screw body has a head portion and a threaded shaft portion that extends along a longitudinal axis from the head portion to a screw tip of the screw body. The tag body defines at least one surface configured to display traceability information for the bone screw. The frangible interface is disposed between the tag body and the screw tip of the screw body. The frangible interface is configured to fracture upon application of a predefined mechanical force so that the tag body is removable from the bone screw.

Abstract: An intervertebral spacer is disclosed having a main body and an articulating component that is pivotally mounted within an opening of the main body. The intervertebral spacer is designed to be manufactured using an additive manufacturing process without the use of any frangible support material between a main body of the intervertebral spacer and an articulating component of the intervertebral spacer. To this end, an article of manufacture is provided in which supports are formed prior to forming intervertebral spacer. The supports are configured to support the main body and the articulating component such that they can be separately, but simultaneously manufactured using an additive manufacturing process atop the supports, without the need for any frangible support material therebetween.

Abstract: A fixation system includes an elongated rod, a fastener, a yoke, and an insert. The fastener includes a head with a truncated top portion. The yoke receives the rod and includes a yoke opening and a yoke cavity. The yoke cavity supports the head allowing for angular movement of the fastener. The insert is inserted into the yoke above the fastener and includes an insert base and a plurality of prongs. The insert base defines a base cavity that provides clearance for the head. The prongs extend away from the insert base and contact the head of the fastener below the truncated top portion. At least one set of the prongs has a length such that when the fastener is moved to a position of maximum angular movement within the yoke, at least one of the prongs is out of contact with the head of the fastener.

Abstract: A corpectomy cage includes a main body, a first end cap, and a second end cap. The main body is shaped as a hollow rectangular prism, and includes a first end and a second end. The first end has a plurality of first receivers formed therein, and the second end has a plurality of second receivers formed therein. The first end cap includes a plurality of first legs configured to be received within respective first receivers to removably engage the first end cap with the first end of the main body. Similarly, the second end cap includes a plurality of second legs configured to be received within respective second receivers to removably engage the second end cap with the second end of the main body. Each of the end caps further includes a plurality of teeth arranged opposite the plurality of legs.
