Abstract:
Objective To analyze the clinical effects of vertebral pedicle bone graft after posterior pedicle screw fixation in the treatment of thoracolumbar fractures .Methods 80 cases with thoracolumbar fractures were ran-domly divided into the study group ( 40 cases ) and control group ( 40 cases ) .The study group used simple pedicle screw fixation , posterior reduction , and the control group adopted conventional inter vertebral internal fixation .The operation time,hemorrhage were compared between the two groups .The clinical effects of posterior transpedicular in-strumentation of bone graft and vertebral pedicle screw in fractured vertebra in the treatment of thoracolumbar fractures were analyzed.Results The operation time of study group was (110.0 ±14.9)min,which was longer than that of the control group[(91.0 ±13.7)min](t=5.93,P<0.05).The intraoperative blood loss of the study group and the control group were (270.0 ±34.4) mL,(258.0 ±42.5) mL,respectively,with no significant difference between the two groups(t=1.38,P>0.05).At the end of the follow-up after the operation,the anterior vertebral height,Cobbangle,VAS scores in the study group were (91.3 ±1.7)%,(11.2 ±1.9)°,(2.5 ±0.2)%,which were better than (86.6 ±2.3)%,(14.5 ±1.1)°,(3.5 ±0.9)% in the control group (t =5.25,3.24,6.17,all P <0.05). Conclusion Vertebral pedicle bone graft posterior pedicle screw fixation in the treatment of thoracolumbar fractures can effectively correct the kyphosis ,reconstruct vertebral height ,increase the stability of the vertebral body ,reduce and prevent postoperative vertebral height lost ,loosening and fracture fixation complications .
