摘要
目的 了解AF内固定失败后断钉与时间的关系 ,以及年龄、性别、植骨及截瘫等因素对断钉的影响 ,指导临床在较为准确的时间取出内固定。 方法 对 3 3例行AF钉内固定的患者进行随访 ,用Cox回归对断钉的失效进行分析。 结果 大部分断钉发生在术后 40 0～ 5 0 0d内 ,而且本研究中断钉率较国内其它相关报道高 ,可能与植骨率较低有关。 结论 AF钉内固定后 ,大多数在术后 40 0～ 5 0 0d开始疲劳断裂 ,因此 ,AF钉在术后一年取钉较佳。
Objective To learn the relation between AF internal fixation breakage and the factors of breakage time, patient's age and sex, presence of paraplegia, fusion. Methods 33 patients who underwent AF internal fixation were analysed with Cox regression. Results The major of AF internal fixation breakage occurred at the time from 400 days to 500 days after the operation. The rate of AF internal fixation breakage in this study was higher than that of other reports. This might relate with the lower fusion rate of this group. Conclusion In order to prevent breakage, the best time for removing the AF internal fixation is at about 1 year after the operation.
