The Applied Research Of The Improved Load-Sharing Scoring System In The Treatment Of Unstable Thoracolumbar Fractures

ObjectiveThe aim of this study was to investigate the clinical value about the improved Load-Sharing scoring system in guiding the proper surgical approach of unstable thoracolumbar fractures.Methods68cases with unstable thoracolumbar vertebral fractures were accepted in our hospital, the surgery and choice of instrumentation of these patients were guided by the improved Load-Sharing scoring system.57cases of them were followed up. The clinical value about the improved Load-Sharing scoring system can be evaluated by observing the clinical effects.ResultsAfter the surgery, the posterior convex angle, the compression percentage and the spinal canal occupation were all obviously reduce. Posterior approach group: 14.2±5.4°,24.3±7.5%,31.7±6.8%; Anterior approach group:24.8±6.6°,37.5±6.6%,48.1±8.4%; Anterior-posterior combined group:27.9±8.5°,44.3±9.7%,59.2±7.6%. There were significant difference between the radiological index of the preoperative and the postoperative (P<0.05).18cases of them with incomplete injury of nerve were recovered1ASIA grade,10cases of them were recovered2ASIA grades, and1cases of them were recovered3ASIA grades. Waist pain was evaluated according to Denis Pain Scale, the results showed P141cases, P212cases, P34cases.No failure of internal fixation was observed in the fixation.ConelusionThe improved Load-Sharing scoring system is a perfect assessment in guiding. proper surgical approach and the choice of instrumentation in thoracolumbar fractures.
