Abstract
An insertion instrument for inserting an expandable support device, where the insertion instrument includes an actuator device operable to rotate a component of an expandable support device to a rotated position, such that the rotation to the rotated position of the expandable support device causes a first longitudinally extending member of the expandable support device to be longitudinally fixed. The insertion instrument also includes a hollow body, where the hollow body includes a removable gear device or a removable screw driver device. The removable gear device is configurable to cause a first longitudinally extending member of expandable support device to longitudinally extend in a direction away from the center of the expandable support device. The removable screw driver device is configurable to insert a screw into the expandable support device to lock the rotated position into place.
