During the follow-up period, 97 patients had presented with CT signs of pedicle screws loosening (1-mm radiolucent zone around at least 1 screw and double halo sign); however, out of those only 39 complained of axial pain with ODI values over 40; those patients underwent revision surgery. Two hundred thirty-six pedicle screws were extracted in total, including 86 in thoracic spine, 138 lumbar, and 12 sacral. Furthermore, the sensitivity and specificity of the X-ray criteria of loosening could be confounded by many factors, such as metal image artifact, intestinal gas, and display angle. Symptoms The main symptom is pain following back surgery. Google Scholar. The main symptom is usually pain, but many things can cause pain; the best way to know if a loose screw is actually the cause is to do x-rays, and then compare them with your older films.
