骨盆骨折3种分型的可信度和可重复性比较

目的 对骨盆骨折Tile、Young-Burgess和AO分型的可信度和可重复性进行分析.方法 选取符合纳入标准的临床和影像学资料完善的骨盆骨折患者100例,由创伤骨科医师按3种分型方法进行分型,8周后打乱顺序再次分型,应用Kappa值和分型一致性进行可信度和可重复性分析.结果 Tile分型前后两个阶段可信度Kappa值分别为0.743和0.745,可重复性Kappa值为0.771;Young-Burgess分型前后两个阶段可信度Kappa值分别为0.587和0.590,可重复性Kappa值为0.691;AO分型前后两个阶段可信度Kappa值分别为0.402和0.406,可重复性Kappa值为0.498.结论 Tile分型较Young-Burgess、AO分型的可信度和可重复性好,易于掌握和应用.

Comparison of reliability and reproducibility of three different classifications in pelvic fracture

Objective To analyze the reliability and reproducibility of three different classification systems of Tile,Young Burgess and AO in pelvic fracture.Methods One hundred cases of pelvic fractures conforming to the inclusion standard and with intact imaging data were selected and classified according to these 3 classification methods by the orthopedic surgeons.The retyping was performed at 8 weeks after disorganizing the order.Then reliability and reproducibility analysis was performed by using the Kappa values and typing consistency.Results The reliability Kappa values during the two periods before and after the Tile classification were 0.743 and 0.745 respectively,and the reproducibility Kappa value was 0.771;the reliability Kappa values during the two periods before and after the Young-Burgess classification were 0.587 and 0.590 respectively,and the reproducibility Kappa value was 0.691;the reliability of Kappa values during the two periods before and after the OA classification were 0.402 and 0.406 respectively,and the reproducibility Kappa value was 0.498.Conclusion the Tile classification has better reliability and reproducibility than the other two classifications in pelvic fracture,which is easy to master and apply.
