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. Why do screws come loose after spinal fusion? Now they are going to extend the rods up further, does that sound right. This cookie is set by GDPR Cookie Consent plugin.

In my practice, I often order a CT scan around 3 months to verify the instrumentation is not loose and there are early signs of bone growth (fusion). Due to inadequate exposure of screw and malfunction of screw tail, 6 screws had no reading of extraction torque. An instrumented fusion can fail if there is not enough support to hold the spine while it is fusing. I do not expect complete fusion at this point, but the scan gives a good idea if the fusion process is progressing. If you have had a lumbar fusion, then there is always the risk of a hardware malfunction, failure or breakage. Spinal fusion surgery might also be performed when a patient has: Fractured (broken) bones from a traumatic injury Abnormal curvatures of the spine from conditions like scoliosis An unstable or weak spine due to tumors or infections Degenerative disc disease resulting in mechanical back pain a No significant difference was found between polyaxial and monoaxial screws. Galbusera F, Volkheimer D, Reitmaier S, Berger-Roscher N, Kienle A, Wilke HJ. In patients with screw loosening, about 41% had some non-aggressive bacteria. TwoStep Cluster was used to clustered screws by torque. .

Our findings showed that X-ray had a sensitivity of 24% and a specificity of 98%, while CT scan had a sensitivity of 22% and a specificity of 95% regarding extraction torque as criterion of screw loosening. The second objective was to identify the risk factors for low extraction torque of pedicle screw that might lead to loosening. Linear regression analysis was used to estimate the relevance between the extraction torque of pedicle screw and other clinical findings. The x rays showed a halo around the screw. The first part is the actual surgery, in which the nerves are decompressed and then the metal implants are placed.
