    摘要: Embodiments of the invention provide a bone screw device including a bone screw with a temporary encasement. In some embodiments, the temporary encasement comprises a biocompatible material that may be an osteoinductive, a hemostatic and or a bacteriocide. Some embodiments include a temporary encasement including a therapeutic. In some embodiments, the temporary encasement comprises a wax. In some embodiments, the screw head is substantially U-shaped. In some embodiments, the screw includes an extension tip extending from the screw shaft. Some embodiments of the invention include a system for percutaneous implantation of a bone screw including a screwdriver shaft rotatably coupled to a screw that includes a temporary encasement. In some embodiments, the screw shaft can be at least partially rotated by the screwdriver shaft. Some further embodiments further include a retractable sleeve at least partially surrounding the screwdriver shaft and the bone screw.
