In various aspects, an expandable implant for use in a surgical procedure includes a distal cage, a proximal cage mechanically connectable with the distal cage, a top expandable assembly, and a bottom expandable assembly. Each of the top and bottom expandable assemblies have a distal portion in communication with a surface of the distal cage and a proximal portion in communication with a surface of the proximal cage. The expandable implant is expandable firstly in a medial-lateral direction, secondly in a lordotic (e.g., angular) direction, and thirdly a cranial-caudal direction. Additionally, the expandable implant may be diagonally symmetrical about a longitudinal axis of the expandable implant.

A vertebral body replacement system having a quick-connecting removable endplate connection mechanism.

A vertebral body replacement system that includes an auto-locking system that is easy to use without additional instrumentation.

A trial insert having a first member having an engagement channel extending from a bottom surface towards a top surface and along a first direction that extends from a first end to a second end. The trial insert has a second member having an engagement member extending away from a top surface and along a second direction that extends from a first end to a second end, where the engagement member is received within the engagement channel, and where the first member is translatable relative to the second member along a longitudinal axis of the trial insert.

A tibial trial insert assembly is disclosed. The tibial trial insert assembly includes a baseplate trial, an insert trial selectively coupled to the baseplate trial, the insert trial including an insert trial body having a first insert trial surface and a second insert trial surface positioned opposite the first insert trial surface, the second insert trial surface abutting the baseplate trial in a coupled configuration, and a trial shim selectively coupled to the insert trial, the trial shim including a trial shim body having a first trial shim surface and a second trial shim surface positioned opposite the first trial shim surface, the second trial shim surface abutting the first insert trial surface of the insert trial in the coupled configuration.
