Abstract

Bone screw drivers are disclosed that apply torque to a threaded shank of a bone screw assembly and receive a cement delivery device to introduce bone cement through the threaded shank. Also disclosed are driver adapters that couple to a driver in order to facilitate application of torque thereto. The driver adapter can decouple from the driver after implanting a bone screw shank to allow the subsequent use of a cement delivery device in combination with the driver. The devices can be reusable and can employ a number of additional components, including retaining and counter-torque sleeves, driving handles, etc. Further, the devices can allow setup of a bone screw inserter assembly outside a surgical field, such that a completed assembly can be passed to a surgeon or other user for immediate use.
