So nerve damage during the operation is the first cause of severe leg pain after a spinal fusion. Meanwhile, by using extraction torque data, we analyzed the risk factors of screw loosening. Sanden [20] reported a 64% sensitivity of X-ray in 79 screws and a 35% rate of screw loosening, but their definition of a loosed screw was an extraction torque of 0.4Nm or less as there were no screws with and extraction torque between 0.4Nm and 0.75Nm. Dr. Jovita Anyanwu answered. By using Twostep Cluster, the distribution of extraction torque of pedicle screws showed two prominent peaks and one valley. Cookies policy.

The diagnostic criteria for loosening developed by X-ray include the radiolucent area (thicker than 1mm) around screw [4,5,6,7,8,9] and the double halo [4, 10] defined as the presence of radiolucent area and radiopaque rim at the same X-ray. 3e.
