Abstract
An instrument may be coupled to a multi-axis expandable intervertebral cage so that the cage may be inserted into an intervertebral space, expanded along multiple different directions, filled with bone graft, and locked with a fastener. The instrument may be part of an instrument set that includes auxiliary instruments to determine implant size, insert bone graft into the cage, and deliver the fastener.
