The worst of the pain begins to subside by four weeks after the spinal fusion surgery. Furthermore, risk factors that might contribute to low extraction torque were also studied. Cookies policy. Google Scholar. Sometimes unsuccessful surgeries are unavoidable, even when carried out by the most competent surgeons. In the fractured vertebrae, the continuity of cortical and structure of trabecula were damaged, which might affect the stability of screw placed in it. There is a dramatic decline in screw numbers between 0.90 and 1.20Nm. This is done because the spine is unstable because of an injury, or because the spine needs to be fixed in place because of pain. A non-union occurs when a spinal fusion procedure fails and the vertebral bones do not fuse together successfully. 3f, g. Analyzing risk factors for low extraction torque of pedicle screw. Just recently My MRI shows that my fusion did not hold and I have a loose screw! Herniated discs are a common . c CT scan showed no gap around the same screw. It simply suggests that some of the metal implants cannot be completely sterile. Other causes include: scar tissue build-up (fibrosis), joint hypermobility, spinal instability, and facet joint problems.
