哈氏棒治疗不稳定胸腰椎骨折脱位

目的 总结哈氏棒在治疗不胸腰椎骨折脱位中的优缺点及注意事项。方法 ８７例均采用哈氏棒治疗。其中６２例预予以椎板切除减压及／或切开硬脊膜探查脊髓，２５例行棘突打孔钢丝固定双棒，６５例做了自体植骨融合术。结果 ４８例经１～１１年随访，平均５年４个月，２２例完全康复，有１４例发生各种并发症。结论 哈氏棒是一种符合生物力学的内固定器材，具有较强的纵向撑开力，能使骨折脱位得到很好复位，但亦具有一些缺点。如术

Treatment of unstable thoracolumbar vertebra fracture and dislocation by Harrington rod

Objective:To evaluate the merits and shortcomings of Harrington rod for the treatment of unstable thoracolumbar vertebra fracture and to discuss the points of attention of the method.Methods:87 cases were treated with Harrington rod.Laminectomy and/or exploration of the spinal cord were performed in 62 cases.Bilateral rods were fixed with the wire through spinal processes in 25 cases.Auto graft of bone were performed in 65 cases.Results: 48 cases were followed up from 1 to 5 years after operation.The average follow up was 5 years and 4 months.22 cases recovered completely,and some various complications occurred in 14 cases.Conclusion:Harrington rod is an effective internal fixation device for the reduction of fracture and dislocation of vertebra with its longitudinal stress.This device corresponds to the biomechanics of the spinal column.But during the operation,complications should be avoided or diminished by performing strict aseptic technique,bending of the rod to a proper physiological curvature which corresponds to injured spine,doing posterior bone grafting and using corset support after operation.
