Abstract
The invention relates to a vertebral body placeholder having a cylindrical inner body (), which can be telescopically inserted into a coaxially arranged, sleeve-shaped outer body (). A detent device that works in one direction is arranged between the inner body () and the outer body (). A number of detent projections () are arranged in succession in an axial direction and form a row () of detent projections. A number of detent notches () are arranged in succession in an axial direction while corresponding to the row () of detent projections. Said detent notches form a row () of detent notches that completely or partially accommodate the row () of detent projections. The invention also relates to a method for assembling said vertebral body placeholder. The aim of the invention is to create a vertebral body placeholder whose overall height can be easily and reliably adjusted, particularly, during implantation. To this end, a groove () for accommodating the row () of detent projections without obstructing it is provided next to the row () of detent notches.
