Methods. Since October 1997, 47 patients with scoliosis received spinal fixation with the TRAFIX instrumentation at the Peking Union Medical College Hospital. T he average age was 14.3 years (range 10 to 38 years). There were 27 idiopathic c ases, 16 congenital cases, 2 cases with Marfan syndrome and 2 with neurofibromat osis. Twelve of the 47 patients underwent anterior release, while 4 patients rec eived the revision approach. The average follow up time was 26 months (13~38 m onths). Results. The measurements of primary coronal deformity before and after surgery were 74°(50°~115°) and 38.7° (11°~95°), respectively. The average curve correction was 54%. The average number of fused segments was 12.5 (7~17) verte brae. The distance between the center of apex and the C7 plumb line was 56.8 mm before surgery (25~107mm) and 31 mm after surgery (10~87mm). Conclusion. The TRAFIX instrumentation provides three dimensional correction wi th refinement, convenience and reliable fixation.展开更多
