Evaluation of pedicle screws applied in the affected vertebra for the treatment of thoracolumbar burst fracture / 中国矫形外科杂志

ABSTRACT

[Objective]To investigate curative effect for thoracolumbar burst fractures by the method of vertebral pedicle screw fixation applied in the with transpedicular bone graft,and consider its indications.[Method]Thirty cases of thoracolumbar burst fractures were treated by vertebral pedicle screw fixation combining transpedicular bone graft.Among them 22 were male and 8 were famale,age ranged 18-64.All of cases were single segment fractures.The average height of anterior border was 35% before the operation,the average of Cobb's angle was 26?,the percentage of midsagital diameter was 55%.According to Frankel's neurological function classification,preoperative neurological function was Grade A in 4 cases,B in 8,C in 5,D in 6,E in 7.[Result]All cases were followed up for 6 to 30 months.All patients' pain relieved distinctly,the average height anterior border was increased to 97%,the average of Cobb's angle was 3.5?,the percentage of midsagital diameter was 92% postoperatively,showing significant difference(P
