Surgical Treatment of Old Thoracolumbar Osteoporotic Compression Fracture and Kyphosis in Eld-erly

Abstract：Objective To evaluate the outcome of vertebral arch wedge osteotomy with internal fixation for old thoraco-lumbar compression fracture and kyphosis in senile osteoporosis patients. Methods Between August 2009 and February 2014, 20 old patients were treated with Vertebral arch wedge osteotomy with internal fixation. The pre-and post-operative Kyphotic Cobb angle,VAS of back pain and Frankel score were accessed. Results The average operative time was 214 min and average bleeding was 753 mL. The average Cobb angle was(43. 5 ± 7. 2)°pre-operatively and(3. 7 ± 1. 8)°post-operatively. There were statistical significant differences between them(P﹤0. 05),with a mean correction rate of 91. 5%. The average VAS of back pain was(8. 6 ± 1. 3)pre-operatively and(2. 2 ± 1. 1)post-operatively,there were statistical significant differences between them(P﹤0. 05). The average Cobb angle was(5. 7 ± 2. 5)°in the last post-operation follow-up,there were not statistical significant differences(P﹥0. 05). The average loss angle was(1. 9 ± 1. 1)°,with a mean losing rate was 5%. No post-operative complications such as artery injury,exacerbation of neurological symptoms. Bony fusion was observed. There were no failure of internal fixation and losing of reduction. Conclusion Vertebral arch wedge osteotomy with internal fixation is effective for old thoracolumbar compression fracture and kyphosis in senile osteoporosis patients.
