![]() ![]() All the patients were operated with mini open thoraco/lumbotomy system (Syn-Frame). ![]() Follow up periods were 6th weeks, 3rd and 6th months and also 1 year postoperatively. Material and Methods: We performed a non-randomized retrospective analysis of the clinical outcome of 138 patients with 140 fractures who underwent mini open thoraco-lumbotomy surgery, between 20. Aim: The aim of this study is to report the outcome of 138 cases who underwent mini open thoraco-lumbar surgery for thoracic and lumbar fractures. Nowadays Mini- Open Anterior Fusion is reported to be a safe and effective alternative treatment for various spinal pathologies. Thus, posterior compression as the last step is recommended in these pathologies.īackground: Several surgical procedures have been recommended for the management of thoracic and lumbar fractures. In addition, posterior compression with cage significantly increased lordosis compared to the distracted state.Īmong different surgical modifications tested, circumferential fixation with final posterior compression as the last step resulted in superior stability and improved sagittal alignment. Additional posterior compression in the presence of a cage significantly decreased flexibility in axial rotation, thus achieving stability comparable to the intact state even in this movement axis. For flexion/extension and lateral bending, flexibility was decreased even compared to the intact state, however, not in axial rotation, being the most critical movement axis. We found that both types of instrumentation with cage stabilized the segment compared to the fractured state in all motion planes. We checked range of motion, neutral zone and Cobb’s angle over the injured/treated segment within the following conditions: Intact, fractured, instrumented in neutral alignment, instrumented in distraction, with cage left in posterior distraction, with cage with posterior compression. Loads were applied as pure bending moments of ± 3.75 Nm in all six movement axes. Testing was performed in a custom-made spinal loading simulator. We hypothesized that additional posterior compression in circumferential stabilization may increase stability by locking the facets, and better restore the sagittal profile.īurst fractures Type A3 were created in six fresh frozen cadaver spine segments (T12–L2). Surgical treatment of thoracolumbar A3-fractures usually comprises posterior fixation-in neutral position or distraction-potentially followed by subsequent anterior support.
