Introduction: Surgical management of thoracolumbar trauma involves correction of posttraumatic deformity and placement of transpedicular instrumentation. The aim of this prospective cohort study was to generate first results reflecting the clinical and radiological outcome of patients treated with percutaneous dorsal instrumentation for fractures 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 patients with fractures 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 Chronic Disability Index (CDI), the Oswestry Disability 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 patients (84.6%), and the radiological follow-up by 21 (80.8%) patients. Our patient population had a mean age of 47.4 +/- 4.1 years. Twelve patients received dorsal instrumentation, and 14 patients were treated with an additional ventral reconstruction. Intraoperative reduction was 11.5 +/- 1.5 degrees among all patients (p < 0.01). A considerable amount of the operative correction was lost after six weeks with a loss of reduction of 4.6 +/- 1.4 degrees (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 degrees among all patients, 8.7 +/- 2.1 degrees after dorsal and 4.9 +/- 1.1 degrees after dorsoventral stabilisation (all p < 0.01). Moreover, all patients had minimal to moderate disability with a CDI 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 fractures. Patients report minimal to moderate disability as a result of their severe injury one year after trauma. We advocate the use of the transpedicular Schanz screw system to correct posttraumatic kyphotic deformity, with secondary anterior fusion in our treatment strategy of thoracolumbar incomplete burst fractures in patients without a neurologic deficit.
