    【Abstract】 Objective To explore the method and effectiveness of reduation and fixation of thoracolumbar fractures by short-level pedicle screws.Methods There were 29 patients in the study group from 6/2002 to 12/2004.Each of them had been injuried in thoracolumbar spine, they were decompression,reducation and fixation by short-level pedicle screws through a posterior approach.Results All patients were followed up from 6 to 30 months(mean 15 months).Twenty seven of them showed an improvement in neural function by one to three levels according to Frankel's classification. The others whose neural function was A level were not improvement.Two cases whose reduction were not catisfactory.Screw of one case was back out.Conclusion Short-level pedicls serews is a better method for thoracolumbar spine through a posterior approach. ......
