INTRODUCTION: The anatomy and biomechanics of the thoracolumbar backbone place these segments at excessive threat of trauma accidents. Remedy choices are both conservative or surgical, and there’s a lack of consensus about the fitting indications. Worldwide scientific publications agree solely on primary surgical rules: vertebral stability, deformity correction, safety of neurological constructions and quick practical restoration. Probably the most generally used method is the posterior method, which permits the very best administration of most vertebral fracture patterns. The intention of this research was to match scientific and radiological outcomes of monosegmental stabilisation with these of bisegmental stabilisation and fusion within the therapy of traumatic thoracolumbar backbone fractures.
MATERIALS AND METHODS: This retrospective scientific and radiological research evaluated 48 consecutive sufferers handled with monosegmental (Group M; n=14) or bisegmental (Group B; n=34) posterior pedicular instrumentation for thoracolumbar fractures. Fractures have been categorized by the brand new AO Backbone TLIC system. Common follow-up was 30 months. Scientific outcomes in each teams have been statistically in contrast. Radiological outcomes have been evaluated when it comes to vertebral anterior physique peak restoration and correction of the kyphotic deformity.
RESULTS: Radiographical outcomes confirmed no statistically vital distinction between the 2 teams in vertebral physique peak restoration and correction of the kyphotic deformity. The imply postoperative somatic vertebral anterior physique peak in Group M was 25.eight±four.52mm and in Group B it was 24.43±four.27mm. In Group M the imply postoperative kyphotic deformity was 11.10±5.71°, in Group B it was 9.09±four.93°.
CONCLUSIONS: The outcomes of this research verify the validity of brief and really brief instrumentation for the therapy of well-selected kind A and B vertebral fractures. In C kind fractures right surgical indication have to be evaluated on a person foundation.
