Event Description

This report is being filed after the subsequent review of the following literature article: m loibl, et al.(2005).Spinal fracture reduction with a minimal-invasive transpedicular schanz screw system: clinical and radiological 1 year follow up.Injury, int.J.Care injured , 46s4, pp.S75-s82.Authors: (b)(6).The aim of this prospective non-randomized 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 (universal spine system fracture.Depuy synthes).26 patients total with fractures of the thoracic and lumbar spine operatively treated with bi-segmental dorsal instrumentation between january and december 2012.22 patients completed clinical follow-up.21 patients completed radiological follow up.Study cohort comprised of 12 women and 14 men.Mean age: 47.4 +/- 4.1 years.Bmi mean: 22.9 +/- 0.7.Fractures were found in various parts of spine: the thoracic, thoraco-lumbar spine, and lumbar.Radiological data acquisition performed: pre- and postoperatively, after 6 weeks, 3, 6 and 12 months.The radiological parameter: cobb angle.Clinical outcome parameter: chronic disability index, oswestry disability index, and spine tango core outcome measurement index.Authors did not define rating scale therefore, the results will not be included.Complications: 1 additional anterior surgery performed due to persistent pain and a medialized screw malposition.This is report 2 of 2 for (b)(4).This report is for an unknown screw related to the universal spine system.A copy of the literature article is being submitted with this medwatch.
