经椎弓根椎体内植骨在胸腰椎骨折后路手术中应用

Application of bone grafting to vertebral body through pedicle of vertebral arch during the posterior operation of thoracic or lumber fracture

目的:探讨经椎弓根植骨治疗胸腰椎骨折中的应用价值。方法:采用经椎弓根植骨治疗胸腰椎骨折28例与前期36例无植骨病例作对比研究。结果:观察组有1例断钉,对照组有7例断钉。两组矫形角度丢失存在显著差异。结论:经椎弓根椎体内植骨能培强椎体早期抗压稳定性,加速骨折坚强愈合,减少内固定长时间过大应力造成断裂、折弯、切割等引起矫形角度丢失。

Objective To evaluate the application of the technique of bone grafting to thoracic or lumber vertebral body through pedicle of vertebral arch. Methods Twenty-eight cases of thoracic or lumber vertebra fracture treated with the technique above-mentioned （experimental group） were compared with 36 cases treated without bone grafting （control group）. Results In experimental group pedicle screw was broken only in 1 case, while in control group pedicle screws were broken in 7 cases. The loss of reshaping spine angle between two groups was significant deviation. Conclusion The technique may reinforce the anti-pressure stability of the fractured vertebra, accelerate bone healing, and reduce losing of reshaping spine angle induced by broken pedicle screw, twisted and cut vertebra.
