Meanwhile, we compared our extraction torque data with X-ray and CT scan findings, the result showed that the specificity of both imaging approaches were excellent, and the peri-screw osteolysis present both in X-Ray and CT scan could indicate low extraction torque of screw anchor, but their sensitivities were less than satisfactory (24% and 22% respectively), regarding detection of screw loosening. If pedicle screws loosen, it may result in new or worsening back pain, leading to failed back surgery syndrome (FBSS). Spine. Overview. Inclusion criteria were persisting midline .
