摘要：
A method for implanting a bone screw in a vertebra may first involve inserting the bone screw and a bone screw delivery mechanism through a proximal end of a guide tube along a first trajectory. A proximal end of the bone screw is attached to a distal end of the bone screw delivery mechanism, and a distal end of the guide tube is positioned adjacent the vertebra. The method may next involve advancing the bone screw and the bone screw delivery mechanism through a bend in the guide tube to cause the bone screw to exit the distal end of the guide tube along a second trajectory and contact the vertebra. The method may further involve rotating the delivery mechanism to cause the bone screw to screw into the vertebra and detaching the bone screw delivery mechanism from the bone screw.
