180 patients with scoliosis (aged 12-29 years) were subjected to the correction of deformation by means of the Harringtone type distractors and spondylodesis with utilization of osseous transplants. In 24 of them (13,3%) the distractor has been broken in different terms after the operation. The danger of the break increases with the age of the patients and abruptly increases in case of scoliosis of the V degree (in excess of 90 degrees) and in case of necessity to bend the distractor to correct the kyphoscoliosis. The distractor break is associated not with the material structure but with the rod design.
180例脊柱侧弯患者（年龄在12至29岁之间）接受了使用哈灵顿式撑开器进行畸形矫正以及利用骨移植进行脊柱融合术。其中24例（13.3%）在术后不同时期撑开器发生断裂。撑开器断裂的风险随患者年龄增加而升高，在Ⅴ度脊柱侧弯（超过90度）以及需要弯曲撑开器以矫正脊柱后凸侧弯的情况下风险会急剧增加。撑开器断裂并非与材料结构相关，而是与杆的设计有关。
