3e. Significant difference was found between different segments (p<0.001) as shown in Fig. 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.

The titanium alloy pedicle screws (Johnson&Johnson, USA; Medtronic, USA; Stryker, USA; Kanghui Med, China; FULE, China) with diameter of 4.0 to 6.5mm and length of 30 to 55mm were used in the primary surgeries.

Regarding extraction torque, there was no significant difference between polyaxial and monoaxial screws (p=0.673) as shown in Fig. The debris elicited an inflammatory cytokine-mediated particulate-induced response through increased expression of intracellular TNF-alpha, increased osteoclastic activity, and cellular apoptosis. 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). The mean torque of the newly implanted screws was 2.730.75Nm (95% confidence interval 1.23 to 4.22). By clicking Accept All, you consent to the use of ALL the cookies.

What are the Treatments for Failed Back Surgery Syndrome? Transfer lesions are most likely to happen after a two-level fusion and are more common in degenerative osteoarthritis conditions, and less common in disc degeneration problems. Other causes include: scar tissue build-up (fibrosis), joint hypermobility, spinal instability, and facet joint problems. Traditionally, it was assessed by radiological approaches, both X-ray and CT (computed tomography) scan, while reports using mechanical method to study screw loosening after spine surgery are rare. Like any surgery, this procedure can also have long-term side effects. Methods: Theater records from a single spinal surgeon's practice were reviewed to identify patients that had undergone lumbar fusion for discogenic back pain with subsequent pedicle screw instrumentation removal (Expedium, DePuy Synthes) in the preceding 3 years with a minimum of 18 months follow-up. The type of surgery needed depends on the type of problem the patient is having. A rod is used to connect the screws which prevents movement and allows the bone graft to heal. .

There are several occasions when spinal fusion can be required or suggested by the doctor when the patient might be experiencing disk related problems, deformities such as curvature of the spine, or even spinal weakness. If, however, the broken screw was pressing on a nerve or obstructing the spinal canal, surgery to remove the instrumentation would be considered. In total, 236 screws were taken out, and the extraction torque data was recorded and analyzed to identify the sensitivity and specificity of both imaging studies for screw loosening. Meanwhile, stress shielding can lead to a decrease of stress transferred through the bone tissue, which can reduce bone mineral density and remodel the bone surrounding the screw. He said I am fused solid at all levels and he assures me the surgery is pretty simple.
