应用VentroFix前路重建腰骶段稳定

目的:经前路切除腰骶段病变,植骨后,行下腰椎到骶1,2的VentroFix内固定,评价腰骶段稳定性. 方法:对接受手术的6例患者术前、术后的影像学资料进行总结. 结果:6例患者经过平均18 mo的随访,内固定无松动、变形,植骨融合腰骶段稳定性良好. 结论:对一些必须前路行腰骶段病变切除的患者,可以在可靠植骨后,行下腰椎到骶骨1,2的VentroFix内固定.

Clinical application of VentroFix anterior instrumentation for reconstitution of lumbosacral stability

AIM: To evaluate the stability of VentroFix internal fixation at lower lumbar vertebra to sacrum (S1~S2) following the resection of lumbosacral lesion and bone graft by anterior approach. METHODS: Six patients with lumbosacral diseases (such as tuberculosis, tumor, discitis, and so on) were employed in this study. All cases underwent VentroFix internal fixation by anterior approach. The preoperative and postoperative imaging data (X-ray, CT and MRI) were obtained and evaluated. RESULTS: All cases were followed up for an average period of 18 months (range, 12-28 months). The radiograms showed a bony fusion. There was no loose or dislocation noted, and the stability of lumbosacral graft was good. CONCLUSION: For the patients with lumbosacral diseases who have underwent the removal of the affected region via anterior approach, VentroFix internal fixation should be performed from lower lumbar to higher sacrum with VentroFix anterior instrumentation after autologous iliac grafting.
