Scofix器械内固定加椎体内植骨治疗胸腰段骨折62例分析

目的 总结应用Scofix器械内固定加经伤椎椎弓根椎体内植骨治疗62例胸腰椎骨折的手术经验。方法 手术中通过椎弓根螺钉系统对脊柱骨折进行复位及固定，并经伤椎椎弓根椎体内植骨，以提高复位效果及骨愈合质量。结果 62例患者得到随访，X线及CT复查提示骨折复位率达90％以上，椎管内有效矢经、横经达到正常；平均骨折愈合时间3个月。结论 该方法具有伤椎复位良好，符合骨愈合的生理要求，能有效地预防术后晚期椎体楔变，神经通道损伤小，利于功能恢复等优点.

Scofix system combined with transpedicular bone graft to treat 62 patients with thoracolumbar fracture

Objective To sum up the clinical experience of treating thoracolumbar fractures with Scofix system and transpedicular bone graft. Methods 62 consecutive patients with thoracolumbar fracture were treated operatively with reduction and stabilization by Scofix system combined with vertebral fusion via transpedicular bone grafting. Results 62 patients were followed up. Their postoperative radiographs and CT scans showed that more than 90%of the cases gained reduction, the effective diameters of vertebral canal became normal and the mean time of vertebral fusion was about 3 months. Conclusions Scofix system is effective in reduction and fixation for thoracolumbar fractures, and transpedicular bone graft is helpful in restoring the height of vertebral body and increasing vertebral fusion. The procedure also has advantages of preventing vertebral collapse, reducing nerve injury and facilitating functional recovery.
