摘要:
A dual drive screw that includes a head and a shaft. The head has a top surface, a first recess in the top surface comprising a first drive and a second recess below the first recess comprising a second drive. The shaft extends from the head opposite the top surface and includes an exterior surface with a thread formed on at least part of the exterior surface. The first drive may be a star drive, a hex drive, a square drive, a 12-point flange, a double square, a double hex, a spline drive or any other drive that has an opening large enough for a device to pass through and engage the second drive in the second recess. A first device engages the first drive and rotates the screw in a clockwise direction. A second device engages the second drive and rotates the screw in a counter-clockwise direction for removal. The dual drive screw is preferably implanted in a person.
