Furthermore, the sensitivity and specificity of the X-ray criteria of loosening could be confounded by many factors, such as metal image artifact, intestinal gas, and display angle. In these cases, spinal cord stimulation (SCS) or narcotic pumps may be used for pain control. An in vivo study of pedicle screw fixation augmenting posterior lumbar interbody fusion.

This may suggest that spine screws could prophylactically be coated with antibiotic material prior to implantation, to help aid in fusion and surgical success. Meanwhile, the strain imposed on pedicle screws might significantly increase when fusion had not been obtained or anterior column support was inadequate. If the patient has symptoms that seem to be coming out of the loose screw or if there is movement of the spine because of loosening of plate or fracture, the .

Can barely lift them to walk, can't stand up from a chair without assistance. During the follow-up period, 97 patients had presented with CT signs of pedicle screws loosening (1-mm radiolucent zone around at least 1 screw and double halo sign); however, out of those only 39 complained of axial pain with ODI values over 40; those patients underwent revision surgery. Surgery for removal of hardware is scheduled for August 26, wish it were sooner, but at least at this point there appears to be hope. Therefore, the actual circumstances of pedicle screw loosening are not acknowledged due to the various diagnostic criteria and conflicting reports. The main symptom is usually pain, but many things can cause pain; the best way to know if a loose screw is actually the cause is to do x-rays, and then compare them with your older films.

We also tested the average torque of newly implanted screws and found that 1.02Nm was lower than the low limit of 95% confidence interval of newly implanted screws. However, like any other metal it can fatigue and break (sort of like when one bends a paper clip repeatedly). The presence of wear debris [23] was reported to induce osteolysis leading to screw loosening. 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.

According to such criterion, the loosening rate was found to be 33%. Furthermore, risk factors that might contribute to low extraction torque were also studied. 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. Further study with larger simple size is needed to confirm the effect of screw length and diameter on extraction torque in the human spine. I hope it hasn't become infected! . b Lateral X-ray showed that the same screw was pulled out (white arrow). A number of factors have been reported to be related to screw loosening.

Villa T, La Barbera L, Galbusera F. Comparative analysis of international standards for the fatigue testing of posterior spinal fixation systems. Extraction torque of pedicle screws inserted in fractured vertebrae was significantly lower than those in non-fractured vertebrae (p=0.009); meanwhile, screws of non-fusion surgery had lower extraction torque when compared to those in fusion surgery (p=0.001). Our results showed a low but significant linear correlation between extraction torque and BMD (p=0.010, R2=0.304, F=8.296) as well as age (p=0.045, R2=0.123, F=4.345), indicating pedicle screw in aged patients or those with low bone density may be less stable according to mechanical measurement, as shown in Figs.
