Abstract

After spinal fixation using conventional stainless steel screw fixation system, postoperative evaluation of spinal canal and identification of screw positions are very difficult because of severe image halation on computerized tomography(CT) or magnetic resonance imaging(MRI). As a result, diagnosis is interfered in cases of screw malposition, infection, and when demonstration of spinal decompression is needed. For this reason, titanium implants have been developed. Titanium is neither magnetic nor paramagnetic, so it produces minimal artifacts on CT or MRI. Titanium pedicular screw system(DipasonTM) is one of these instruments. In this study, the authors investigated the compatibility of this instrument with CT and MRI postoperatively. The use of titanium pedicular screw system permits high quality image of spinal cord, nerve root and screws on CT and MRI.
