TENOR内固定系统治疗胸腰段脊柱不稳定骨折

目的应用TENOR内固定系统治疗胸腰段脊柱不稳定骨折开观察其临床效果。方法采用TENOR内固定系统治疗胸腰段脊柱不稳定骨折26例，同时行横突间、关节突植骨融合。椎体的复位控制在伤椎原有高度的90％左右。结果随访时间平均12．5个月。26例均固定坚固，无1例断钉、断棒及螺钉松动。26例植骨均融合，22例伤椎椎体高度恢复，4例残留20％～30％的压缩未恢复。神经功能恢复按ASIA分级，3例A级未恢复，其余均有1级以上恢复。结论TENOR脊柱系统操作简便，可实施三维矫正固定并可定量调节复位，固定坚固。椎体的复位控制在伤椎原有高度的90％左右，可减小伤椎椎体内的空隙，可能有利于椎体骨折愈合，增加前柱、中柱的稳定性。

TENOR fixation system for treatment of thoracolumbar unstable fracture

Objective To introduce Tenor fixation system for the treatment o f thoracolumbar unstable fractures and to evaluate its clinical effect. Methods 26 patients with thoracolumbar unstable fractures were treated with Tenor fixation system and received posterolateral fusion. The vertebral body restoration was c ontrolled to preserve about 90%of the normal height. Results The average follow -up time was 12.5 months. Firm fixation was found in all the 26 cases, and no b roken nail or rod or loosening screw was found. Spinal fusion was obtained in al l the patients. 22 cases had normal vertebral body restoration, but 4 cases stil l had compression of 20 to 30%of the vertebral body. According to ASIA motor sc oring system, 3 patients of grade A did not resume their normal neural function. The rest gained neural functional recovery of at least one grade. Conclusions T he easy Tenor fixation system allows three dimensional rectifying fixation and q uantitative adjustment reduction, and provides firm fixation. Since vertebral re duction can be controlled to 90%of the normal height to diminish the interspace between injured vertebral bodies, it facilitates fracture healing, and enhances stability of anterior and middle columns.
