椎板翻转减压回植术治疗胸腰段骨折伴脊髓损伤

Treatment of thoracolumbar vertebral fracture with spinal cord injury by turn over decompression and regrafting of vertical lamina

目的：评估椎板翻转减压回植术治疗胸腰段骨折伴脊髓损伤的疗效。方法：通过X线、CT、MRI影像学检查，Frankel脊髓神经功能评价，比较椎体恢复高度和椎管减压的程度，神经功能Frankel's分级的改善情况。结果：椎体恢复高度＞85%，椎管受阻较术前改善为78.3%，脊髓神经功能有Frankel Ⅰ级以上改善为91.3%。结论：椎板翻转减压、复位，可使脊髓神经功能得到有效恢复，回植椎板符合脊柱解剖学生理特点。

Objective:To evaluate the results of 23 case s of thoracolumbar vertebral fracture with spinal cord injury by turn over decom pression and regrafting of vertical lamina.Methods:The postoperative and preoperative X－ray and CT and MRI wer e used and the all neural function were assessed in accordance with F rankel grade to compare the restoration of the height of vertebra and the effica cy of decompression of the spinal cord.Results:The high degree of vertera were recovered larger than 85%.Th e CT evaluation showed that the obstruct of spinal canal has improved in 78.3%.N eurologic function improvement of more than one Frankel grade was 91.3%.Conclusions:The neurologic function has improved and the stability of posterior spinal column has recovered with turn over decompres sion and regrafting of vertical lamina.
