Event Description
This report is being filed after the review of the following journal article: pavlov, p. W. Et al. (2004), good outcome and restoration of lordosis after anterior lumbar interbody fusion with additional posterior fixation, spine, vol. 29, number 17, pages 1893-1900 (netherlands). The aim of this study is to evaluate clinical performance of alif with syncage supplemented with posterior fixation, with special emphasis on the safety and efficacy of the surgical procedure and the ability to restore sagittal alignment, restore intervertebral height, and fuse the motion segment. Between october 1996 and february 1998, there were 33 patients (24 males and 9 females) with an average age of 36 yrs (range, 24¿57 yrs) in the single group and 19 patients (12 males and 7 females) with an average age of 39 years (range, 25-55 yrs) in the double-level group were treated with an intervertebral syncage (mathys ag bettlach, bettlach switzerland), 4. 5-mm titanium screws (synthes, oberdorf, switzerland) and pedicle screws (universal spine system). The follow-up period was 4 years. The article did not specify which of the devices were being used to capture the following complications: 1 patient, 1 of the translaminar screws broke. 10 months after primary surgery, a refixation was performed with a facet screw, and it was found that the motion segment was not fused. At the 2-year follow-up observation, there were no radiologic signs of nonunion. This report is for an unknown uss pedicle screw. This is report 5 of 6 for (b)(4).
