USA、Z-Plate前路钢板内固定治疗胸腰段陈旧性骨折

Treatment for Thoracolumbar Vertebrae Old Fractures with USA-Plate or Z-Plate Internal Fixation

目的:介绍和评估USA-Plate和Z-Plate在治疗胸腰段陈旧性骨折中的作用及价值。方法:对19例胸腰段陈旧性骨折患者行椎管侧前方减压,USA-Plate内固定11例,Z-Plate内固定8例,观察术前、术后神经损伤ASIA分级。结果:随访时间6月-18个月,平均10.6个月。ASIA分级:术前A4例,B3例,C7例,D5例;术后A3例,B1例,C4例,D3例,E7例, 1例失随访。结论:USA-Plate和Z-Plate具有稳定性好,使用方便、安全,不影响MRI检查,是理想的前路短节段固定系统。

Objective: To introduce and evaluate the efficacy of USA-Plate and Z-Plate in the treatment of thoracolumbar vertebrae old fractures. Methods: nineteen patients with old fractures of thoracolumbar vertebrae were treated by anterolateral decompression and USA-late or Z-Plate internal fixation. The ASIA impairment scale was observed before and after operation. Results: Eighteen patients were followed-up for 10.6 months on average (from 6 to 18 months), except one was lose followed-up. The ASIA impairment scale had proved that there were 3 cases with A, one with B, 4 with C, 3 with D and 7 with E. Conclusion: USA-Plate and Z-Plate system had the characteristics of stability, simplicity and safety. It has no disturbance to postoperative exam of MRI. They are good anterior fixation system.
