Abstract:
The present invention is directed to a pedicle screw fixation system which can be made for either posterior cervical, thoracic, lumbar spine, or elsewhere. With this type of system a surgeon can implant a pedicle screw system utilizing the same instrument set for an open or closed procedure. The system is designed to avoid cross threading and splitting of tulip heard by use of an outer threaded tulip and reducing donut. The system also provides the ability for superior angulation for hard to reach areas that are common in spinal procedures. The system allows for a bio-absorbable part (the reduction donut) that enhances fusion in the coming months after the procedure. With the elongate tulip portion of the system the user is able to avoid the need for other cannula type instruments; the need of additional parts; the need of additional instruments which could introduce bacteria into the patient and the need for fluoroscopy. The system is completely cannulated so as to permit a HOLDING wire driven procedure. The rods employed with these pedicle screws can be either flexible or rigid. Preferably a rod which is octagonal in cross section is employed with the system so as to prevent rotation in the tulip and slippage.
