Abstract:
At the present time the treatment of the burst type vertebral fracture of the thoraco-lumbar union continues being controverted. Within operative treatment, the most frequent and accepted it is the short posterior transpedicular assembling with or without instrumentation of the fractured vertebra. In the bibliography we did not find any study that compares both methods of treatment. Our hypothesis of work is to evaluate with as from both methods the best radiological results are obtained. For this reason, we evaluated: the correction and the stability of the anterior column; the correction of the deformity and the restoration of the alignment in the sagital plane and failure rate of the vertebral assembly. We analysed of retrospective form two groups of patients, that they fulfil the 15 established criteria of inclusion in the study. The group A is the patients with instrumentation of the fractured vertebra. And group B is the patients without instrumentation of the fractured vertebra. The data and the iconography of 43 clinical histories are gathered and analyzed by an only observer. Of all patients we gather of preoperative form, postoperative and whem fulfilling minimum the year of evolution, the simple x-rays in the antero-posterior and lateral plane. All x-rays are digitized by means of the scanner marks: Epson GT-12000, by means of driver Epson Twain Pro-32 (version 1.01) . By means of the use of the computer science program Micrografx Picture Publisher 8.0, the different images are processed to improve the quality of the same ones. AutoCAD 2000 in Spanish computer science program is used in order to determine a series of angles and adimensionals measures, that they allow us to make the measurement of different angles and to apply the meth
