Pyramesh钛网配合Z-plate治疗严重胸腰椎爆裂性骨折

Pyramesh and Z-plate for severe thoracolumbar burst fractures

目的探讨Pyramesh钛网配合Z-plate在治疗严重胸腰椎爆裂性骨折中的应用价值.方法16例胸腰椎爆裂性骨折伴脊髓或马尾损伤患者进行前路椎体次全切除减压,自体碎骨装入Pyramesh钛网后行椎体间植骨,加用Z-plate内固定.结果术后随访3～13个月,平均9.5个月,全部病例椎间植骨均牢固融合,椎间高度和生理曲度保持满意,神经功能恢复良好,钢板螺钉未松动.结论采用Pyramesh钛网配合Z-plate治疗胸腰椎严重爆裂性骨折可使椎管减压彻底,植骨融合率高,能有效的维持椎间高度和生理曲度,有利神经功能恢复,是治疗严重胸腰椎爆裂性骨折的理想方法之一.

Objective To investigate the value of Pyramesh and Z-plate for severe thoracolumbar burst fractures. Methods 16 cases of thoracolumbar burst fractures with spinal cord or equina cauda injuries were treated with anterior subtotal vertebrectomy, Pyramesh with bone debris intervertebral implantation and Z-plate fixation. Results All cases were followed up for 3~13 months, 9.5 on average. All the intervertebral bone graft got solid fusion. The intervertebral height and physical curve recovered well. The neural function recovery was satisfactory. No instrument looseness was found. Conclusions It provides complete spinal canal decompression, high fusion rate and effective recovery of intervertebral height and physical curve in the treatment of severe thoracolumbar burst fractures with Pyramesh and Z-plate, which are beneficial for neural function recovery. It is an ideal way for severe thoracolumbar burst fractures.
