1. A system comprising:
a vertebral body implant configured to engage a first vertebra and a second vertebra of a spine, wherein the vertebral body implant comprises:
an intermediate expansion member that extends between a first end and a second end along a longitudinal axis and is configured to transition between a collapsed state and an expanded state to adjust a length thereof, and
a first endplate and a second endplate that are configured to couple to the first end and the second end, respectively, of the intermediate expansion member; and
an expansion tool comprising a distal engagement region configured to releasably engage the intermediate expansion member and to adjust the length to a desired length,
wherein the intermediate expansion member comprises:
an outer core having an internal diameter comprising a first plate attachment feature at the first end;
an inner core having an outer diameter comprising a second plate attachment feature at the second end; and
an adjustment ring comprising an attachment feature configured to longitudinally fix the adjustment ring to the outer core, and an internally threaded portion configured to threadably engage an externally threaded portion of the inner core,
wherein the inner core is configured to translate along the longitudinal axis relative to the outer core and the adjustment ring, and
wherein the inner diameter of the outer core is larger than the outer diameter of the inner core.
