Ventrofix在胸腰椎前路手术中的临床应用

目的： 探讨Ventrofix内固定系统在外科治疗胸腰椎疾患的应用价值。方法： 对29例胸腰椎疾患进行前路伤病椎切除、椎管减压、椎体间植骨及Ventrofix内固定。结果： 术后随访3~15个月，经影像学观察及Frankel分级评定脊髓功能，29例胸腰椎术后均获得良好的固定，无内固定松动、断裂或损伤脊髓神经；全部病例植骨呈骨性融合，脊髓功能改善率为63%。无肿瘤、结核复发；术后出现1例肺不张，1例胸膜炎，1例胸痛和1例失血性休克。结论： 胸腰椎疾患前路手术治疗中一期重建脊柱稳定性具有重要意义。Ventrofix具有良好的生物相容性和生物力学稳定性，是目前胸腰椎前路手术中良好的内固定系统。

Clinical value of Ventrofix in the treatment of thoracolumbar spine disorders

Objective To investigate the clinical value of Ventrofix system in the treatment of thoracolumbar spine disorders.Methods Twenty-nine patients of thoracolumbar spine disorders were treated by anterior verterbrae body incision, canal decompression, bone graft by iliac or titanium cage,and fixation with Ventrofix system.Results All operations were successful. Complications included: low blood volume shock in the operation in one patient, atelectasis in one patient, pleuritis in one patient, and transient chest pain in one patient. All patients were followed up for 3~15 months.All patients got a good bone fusion, and the spinal cord funciton improved to a certain degree.There was no recurrence in patients with tumor and tuberculosis.Conclusion The anterior focal cleaning and instrumentation is important in treating thoracolumbar spinal disorders.Ventrofix system is an excellent anterior internal implant system for thoracolumbar spinal disorder, with good biomechanical stability and biosuitbility.
