Abstract:
Objective To compare the clinical effect of the two surgical methods of posterior pedicle screw fixation decompression in treatment of thoracolumbar burst fractures,and in order to provide the basis for choosing the rational treatment.Methods Retrospectively analyzed the clinical data of 98 patients with thoracolumbar burst fractures underwent surgery of posterior pedicle screw fixation decompression from January 2007 to January 2011.Fifty-six patients were given posterior fixed indirect decompression surgery (indirect decompression group) and 42 patients were given posterior fixed direct decompression (direct decompression group).The patients were followed up for (1.03 ± 0.36) years after surgery,the image,recovery of neurological function,postoperative complications and capacity for independent living of the two groups were compared and evaluated.Results After surgery,the vertebral height ratio,Cobb angle,canal compromise rate in indirect decompression group were (91.67 ± 26.19)％,(10.10 ± 2.89)°,(18.61 ±5.32)％,in direct decompression group were(86.23 ± 24.64)％,(11.98 ± 3.42)°,(22.37 ± 6.39)％.There was significant difference compared with before surgery (P ＜ 0.05) and no significant difference between two groups (P ＞0.05).After surgery,the neurological function of the two groups were improved,and the improvement in indirect decompression group was better than that in direct decompression group (P ＜ 0.05).The postoperative complications ratio in indirect decompression group was 23.2％ (13/56),significantly lower than that in direct decompression group[83.3％(35/42)](x2 =10.370,P＜ 0.01).There was 60.7％(34/56)patients with capacity for independent living in indirect decompression group,significantly higher than that in direct decompression group [40.5％ (17/42)] (x2 =4.329,P ＜ 0.05).Conclusion The posterior pedicle screw fixation indirect decompression in treatment of thoracolumbar burst fractures is a feasible operation method,and is worth to utilize in clinic.
