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

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.

The comparison of therapeutic effect between two different methods of cervical spine anterior and posterior in treatment of cervical spondylotie myelopathy / 中国基层医药

Objective To investigate the prognosis of two decompression approaches for cervical spondylotic myelopathy. Methods 86 cases were divided into two groups. 40 cases were underwent decompression by anterior decompression, fusion and internal fixation with titanium screws and plate and 46 cases underwent posterior single opendoor laminoplasty. To investigate the prognosis of two decompression approaches for single compressive segment, two compressive segments, three compressive segments and four compressive segments. Results All cases were followed up for 20 ～ 73 months with an average of 43 months. The mean JOA recovery rate was significant different between single compressive segment group (P ＜ 0.05), and no significant difference between two compressive segments and three compressive segments(P ＞ 0.05), and significant difference between four compressive segments groups (P ＜0.05). Conclusion For single compressive segment, the anterior surgery has a good surgical result,for two or three compressive segments, anterior and posterior surgery had same effect, for the four compressive segments, posterior surgical effect was good.
