Radiological outcomes of unstable thoraco-lumbar fractures without neurological deficit treated through percutaneous surgery

摘要: Abstract Objective To analyse the radiological outcomes in long term of unstable thoracic and lumbar fractures treated through percutaneous surgery. Material methods Retrospective review a series patients with minimally invasive surgery between 2010 2015 three different hospital centres. Six parameters were measured annually during 2-year period: Fracture angle, kyphotic deformity, sagittal index, percentage compression, degree displacement deformation angle. Results A total 37 included median age 41.3 years follow-up period 2.2 years. angle rose from 14.8 to 17.1 (increase 15.54%), deformity 15.9 17.7 11.32%), index 10.1 12.3 21.78%), compression 32.7% 36.8% 12.53%), 3.0 mm 4.4 mm 50%) 20.7 22.9 10.62%). Conclusions All studied lost correction throughout 24 months follow-up; most marked. Nevertheless, greatest loss occurred first postoperative year, then stabilised over follow up. We routinely recommend measurement all previous for up
