INTRODUCTION: Surgical management of thoracolumbar @entity130 involves correction of @entity85 and placement of transpedicular instrumentation. The aim of this prospective cohort study was to generate first results reflecting the clinical and radiological outcome of @entity1 treated with percutaneous dorsal instrumentation for @entity174 of the thoracic and lumbar spine with the use of a transpedicular new Schanz Screw system (USS Fracture MIS, DePuy Synthes). METHODS: A total of 26 @entity1 with @entity174 of the thoracic and lumbar spine were operatively treated with bi-segmental dorsal instrumentation between January and December 2012. Radiological data acquisition was performed pre- and postoperatively, after six weeks, three, six, and twelve months. The radiological parameter of interest was the bi-segmental kyphotic end plate angle (Cobb angle). The @entity717 ( @entity717 ), the @entity717 Index (ODI), and the Spine Tango Core Outcome Measurement Index (COMI) were applied to investigate the clinical outcome. RESULTS: The clinical follow-up was completed by 22 @entity1 (84.6%), and the radiological follow-up by 21 (80.8%) @entity1 . Our @entity1 population had a mean age of 47.4    4.1 years. Twelve @entity1 received dorsal instrumentation, and 14 @entity1 were treated with an additional ventral reconstruction. Intraoperative reduction was 11.5    1.5   among all @entity1 (p < 0.01). A considerable amount of the operative correction was lost after six weeks with a @entity393 .6    1.4   (p < 0.01). At one year follow-up, the measured loss of reduction was significant in comparison to the postoperative state, 6.9    1.3   among all @entity1 , 8.7    2.1   after dorsal and 4.9    1.1   after dorsoventral stabilisation (all p < 0.01). Moreover, all @entity1 had minimal to moderate disability with a @entity717 of 1.8    0.4 (0 - 7), and an ODI of 15.6    3.6 (0 - 60). CONCLUSION: The new transpedicular Schanz screw system can deliver a correction and stabilization of thoracic and lumbar spine @entity174 . @entity1 report minimal to moderate disability as a result of their severe injury one year after @entity130 . We advocate the use of the transpedicular Schanz screw system to correct posttraumatic @entity85 , with secondary anterior fusion in our treatment strategy of thoracolumbar incomplete @entity174 in @entity1 without a @entity51 .
