Abstract
A corpectomy cage is provided with upper and lower telescoping members which move axially between extended and retracted positions. A fixed length sleeve fits over the telescoping members. The sleeve is load bearing to support axial loads on the cage from vertebral bodies. The sleeve also prevents the telescoping members from retracting and encloses an internal cavity within the cage for packing bone fusion material.
