Abstract
Objective To investigate which kind of surgery treatment is more worth promoting by reviewing the outcomes of two different surgical treatment about thoracic vertebral hemangioma with extraosseous extension causing spinal cord compression.Methods From Jan.2008 to Feb.2012,we investigated the two different surgical treatment of 21 cases of thoracic vertebral hemangioma(TVH) having spinal cord compression,which were divided into two groups (group A and group B).Group A:10 cases of patients with extraosseous extension and spinal cord compression were operated on through anterior approach to resect the involved vertebral body and intracanal angioma,and bone graft and internal fixation were also completed in one-stage; Group B:11 cases with bone cement injection,spinal decompression and internal fixation.Patients were followed up for 6 to 18 months,with an average of(10.0 ± 2.3) months.The recovery of neurological function and the pain relief were measured by visual analogue scale (VAS) score and Japanese orthopaedic association (JOA) score.Results In all 21 cases with neural lesion symptoms received open surgery with neurological symptoms partially regained.All patients of two groups were followed up.The blood loss during operation in group A was(1450 ±30) ml,the blood loss during operation in group B was(910 ±50) ml.The JOA score and VAS score had a significant recovery at 3 days,6 months and at last follow-up when compared with preoperative values (P ＜ 0.05); The difference between group A and group B was statistically significant at 3 days after surgery(P ＜0.05) ;The score of JOA and VAS of group B(JOA 10.2 ±2.5 and VAS 3.8 ±0.8) was significantly better than that of group A(JOA 7.8 ± 1.9 and VAS 5.1 ± 1.0) ; But there was no significant difference between the two groups in statistics at 6 months and at last follow-up(P ＞ 0.05).Conclusions The surgical treatment of bone cement injected by the pedicle,spinal decompression and pedicle screw fixation,is a better surgical techniques,because the patients' postoperative recovery is quick,and complications is significantly reduced. Key words: Thoracic vertebrae hemangioma; Spinal cord compression; Bone cement; Spine removed; Pedicle screw system
