Abstract
An inserter for attaching a modular yoke to a bone screw and for providing an indication of attachment, comprises a tubular body having a central lumen, distal and proximal ends, and an attachment portion for releasable attachment to a yoke having a bottom opening for receipt of a head of said bone screw. The inserter includes an inner shaft having a distal end configured to be received into the yoke, the shaft being axially movable within the lumen from first to second axial positions in response to the introduction of the bone screw head into the yoke bottom opening. An indicator button supported by the body is movable in response to axial movement of the shaft from a first indicator position indicating the first axial position of the shaft relative to the body to a second indicator position indicating the second axial position of the shaft relative to the body.
