摘要
目的初步探讨3D打印人工椎体在脊柱结核术后翻修的应用。方法对本院收治的1例脊柱结核术后内固定断裂松动患者应用3D打印人工椎体重建病椎稳定性,并使用相应评分体系及影像学评估手术效果。结果患者临床症状明显缓解,腰背部VAS评分显示疼痛明显缓解,Frankel评分显示神经功能得到明显恢复。CT显示人工椎体植骨以及侧方植骨融合良好,无内固定松动断裂。结论3D打印人工椎体可用于脊柱结核术后翻修,重建患者病椎稳定性。
Objective To investigate the application of 3D printed artificial vertebral body in the revision of spinal tuberculosis after surgery.Methods In this study,a patient with fracture and loosening of internal fixation after spinal tuberculosis surgery was treated in our hospital with 3D printing artificial vertebral body to establish stability of the affected vertebrae,and the corresponding scoring system and imaging were used to evaluate the surgical effect.Results The patient’s clinical symptoms were significantly relieved,the lumbar and back VAS score showed significant relief of pain,and the Frankel score showed significant recovery of nerve function.CT showed that the artificial vertebral bone graft and the lateral bone graft were well fused without loosening or fracture of internal fixation.Conclusion 3D printed artificial vertebrae can be used for revision after spinal tuberculosis surgery to rebuild the stability of patients’diseased vertebrae.
