【摘要】 目的观察人工椎体置换治疗脊椎转移性肿瘤的疗效。方法采用无磁性的医用钛金属加工成可调式中空人工椎体,用于治疗脊椎转移性肿瘤12例。观察术后疼痛缓解和脊髓功能恢复情况及手术椎节的稳定性。结果随访6～34个月,平均11.5个月。脊髓功能障碍术后明显改善,尤以神经根性疼痛缓解迅速。X线摄片定期观察人工椎体稳定,椎间高度恢复良好。结论可调式中空人工椎体可撑开施术椎节,缓解神经压迫症状,并能提供即刻稳定,可用于治疗脊椎转移性肿瘤。更多还原

【Abstract】 Objective To observe the results of the metastatic tumor of spinal vertebra treated with replacement of the artificial vertebral body. Method An adjustable hollow artificial vertebral body was made from titanium for medical use. 12 patients with the metastatic tumors of the vertebral body were treated with this technique. The relief of the pain and the function of spinal cord were monitored. The stability of the operated segments was observed.Results The patients were followed up from 6 to 34 months with an average of 11.5 months. The neurological functions were improved markedly, especially for the pain relieving. The implants were stable and the reconstruction of the segment height was observed on the X-ray films. Conclusions The height of anterior column and the stability of the operated segments can be reconstructed by implanting the adjustable hollow artificial vertebral body. This technique may be an alternative method for the treatment of the metastasis in spinal vertebral body.更多还原
