Although lumbar spine fusion surgery is one of the most commonly performed spine surgical procedures, it is associated with the risk of perioperative complications as well as death [1]. California Privacy Statement, Patients with fusion surgery were considered to get better stability than those without fusion; hence, screws in fused spine might share lower strain and have higher torque.

My doctor says the fusion did not take. Like any surgery, this procedure can also have long-term side effects. 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.
