【摘要】 目的探讨后路经椎弓根椎体楔形截骨治疗胸腰椎创伤性后凸畸形的疗效。方法对18例胸腰椎创伤性后凸畸形患者采用后路经椎弓根椎体楔形截骨治疗。结果患者均获随访,时间24～62(47.7±9.5)个月。神经损伤ASIA评分:术前为25～44(34.6±7.2)分,末次随访时为35～50(47.7±9.5)分,较术前平均提高13.1分±3.1分。椎体后凸Cobb角:术前为21°～35°(27.89°±4.63°),术后为2°～8°(4.13°±0.87°),较术前平均改善23.7°±3.3°,末次随访时丢失1.3°±0.2°。随访期内未出现深部感染、椎弓根断裂及神经损伤加重等并发症。结论采用后路经椎弓根椎体楔形截骨治疗胸腰椎创伤性后凸畸形效果显著。更多还原

【Abstract】 Objective To explore the treatment of transpedicular decompression and pedicle screw fixation for the treatment of kyphosis after thoracolumbar fractures.Methods 18 cases of kyphosis after thoracolumbar fractures were treated through transpedicular decompression and pedicle screw fixation.Results All the patients were followed up 24 ～ 62(47.7 ± 9.5) months.Preoperative ASIA score was 34.6 ± 7.2(range: 25 to 44).The ASIA motor scores of the patients were 47.7 ± 9.5(range: 35 to 50) and the patients improved their neurologic function by about 13.1 ± 3.1 ASIA motor scores at final follow-up.The preoperative kyphotic angle was 27.89° ± 4.63°(range: 21°to 35°).The mean postoperative kyphotic angle was 4.13° ± 0.87°(range: 2°to 8°) and the kyphotic angle of correction was 23.7° ± 3.3°,there was only about 1.3° ± 0.2° of Cobb angle lost at final follow-up.Complications were not found including deep infection,pedicle screw breakage and spine injury increased.Conclusions The treatment of transpedicular decompression and pedicle fixation is significant for kyphosis after thoracolumbar fractures.The technique is a recommended treatment for kyphosis after thoracolumbar fractures.更多还原
