Abstract

Vertebral implants that may be movable between collapsed and expanded orientations to space apart first and second vertebral members. The implants may include first and second contact surfaces to contact against the vertebral members. The implants may include nested struts. The implants may have a first height measured between the contact surfaces in the collapsed orientation with a first amount of overlap in the struts. The implants may have a second height in the expanded orientation with a lesser amount of overlap in the struts.
