Scoliosis surgery involves fusing the most-tilted vertebrae of the spine into one solid bone to prevent further progression, not to correct the abnormal spinal curvature. First, although this was a prospective and blinded designed study, the relatively small number of patients enrollment and the heterogeneity of screw size and position might render our findings susceptible to confounding factors. 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. Google Scholar. The screws were clustered into three clusters based on torque by Twostep Cluster as shown in Fig. This means some risks and things that could happen are not necessarily preventable and are things that just COULD happen. However, you may visit "Cookie Settings" to provide a controlled consent. How do I know if my spinal fusion has failed? Second, the lack of pedicle torque during primary surgeries made it unable to observe the longitudinal change of torque and the influence of inserting torque on screw loosening.

A blood sample will be drawn for analysis, including a blood count. 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. 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. Rods, screws and plates are all co. 651-219-7292 .
