Abstract
A placement tool for positioning a multipart cannulated screw assembly to fixate first and second bone elements. The placement tool includes a stem and a head carried on the stem. The head has an outer shank engagement provision that engages the proximal end of an outer shank of a bone screw assembly and permits selective rotation of the outer shank. The head also has an inner shank engagement provision that engages the proximal end of an inner shank of the bone screw assembly and permits selective rotation of the inner shank. The inner shank and outer shank engagement provisions are connectable to one another such that the inner shank and outer shank engagement provisions rotate together.
