In these cases, spinal cord stimulation (SCS) or narcotic pumps may be used for pain control. Is it easy to get an internship at Microsoft? I just had another MRI today and I now have more problems. 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.
