Abstract
A system includes a tool assembly and an expandable spinal implant. The tool assembly includes a first tool and a second adjusting tool. The first tool has first and second engagement prongs positioned at a first distal end and the first tool defines an adjusting tool passage. The second adjusting tool can extend through the adjusting tool passage of the first tool. The expandable spinal implant includes a first expandable spinal implant structure, a second expandable spinal implant structure, and an adjusting screw having a screw head and a threaded portion. The expandable spinal implant defines first and second tool engagement indentations. The adjusting screw is positioned within the expandable spinal implant such that the second adjusting tool can extend through the adjusting tool passage to engage the screw head while the first and second engagement prongs are engaged with the first and second tool engagement indentations.
