三种人工椎体置换治疗脊柱肿瘤的临床比较

Comparing the Results of Spinal Tumors Treated with Three Kinds of Artificial Vertebral Body

目的 :观察比较三种人工椎体置换治疗脊椎肿瘤的临床效果。方法 :采用LIFT、Rezaian和可调式中空人工椎体治疗脊柱肿瘤 19例。定期X线片检查 ,观察手术椎节的稳定性、疼痛改善及脊髓功能恢复情况。结果 :随访 7～34个月 ,平均 11个月。术后疼痛缓解 ,脊髓功能恢复明显。三种人工椎体稳定 ,无移位。LIFT和可调式中空人工椎体体内植骨有利融合 ,椎节高度恢复满意。结论 :椎体肿瘤切除人工椎体置换能重建手术椎节的稳定性 。

Objective: To observe and compare the results of spinal tumors treated with three kinds of the artificial vertebral body. Method: Nineteen patients with spinal tumors were treated with LIFT, Rezaian or hollow artificial vertebral body replacement. X ray films were taken to observe the stability of the operated segments. The relief of the pain and the function of spinal cord were monitored. Results: The patients were followed up from 7 to 34 months with an average of 11 months. The neurological functions were improved markedly, especially for the pain relieving. The implants were stable without displacement. The bone grafts placed into LIFT and hollow artificial vertebral body were benefit to the fusion. The height of the operated segment was reconstructed satisfactorily. Conclusion: The stability of operated segment was reconstructed by replacement with the artificial vertebral body after the corpectomy. The selection of the different techniques may be based on the character and extension of the tumors.
