The majority of these fractures are AO type A3 ("burst fractures").

The indications for the selection of an ideal treatment for these fractures without neurological deficits remain controversial. The purpose of this study is to evaluate whether patients with thoracolumbar fractures without neurological deficit being surgically treated show faster recovery and better improvement of function than patients being conservatively treated.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': "140 subjects patients with thoracolumbar fractures will be assigned to ei-ther conservative or surgical treatment depending on the surgeon's decision.
