Anterior combined with posterior fixation and vertebra reconstruction for unstable lumbar burst fracture via small incision alone posterior median line / 中国基层医药

ABSTRACT

Objective To explore the clinical effect of anterior combined with posterior fixation and vertebra reconstruction for unstable lumbar burst fracture via small incision alone posterior median line.Methods This study was based on 40 patients suffering from unstable lumbar burst fracture,who underwent anterior combined with posterior fixation and vertebra reconstruction.All the patients were followed up for 1～2 years.The shape and the function of spinal column were estimated in preoperative stage,postoperative stage and the duration of following.The data in the formal 3 stages were compared.Results Between the preoperative and postoperative data,there were statistically significant differences in the Cobb's angle,angle of kyphosis,anterior height of the fracture vertebral body,sagittal index and JOA scores(t=34.085,31.604,27.988,23.798,31.834,all P＜0.05).But no similar result was detected between the postoperative data and the data during the following(P＞0.05).Conclusion Anterior combined with posterior fixation and vertebra reconstruction via small incision had a significant effect in unstable lumbar burst fracture,and it was worthy of further study and clinical popularization.
