Abstract

Introduction: The Judet and Letournel classification is the most widely used classification system for acetabular fractures. Some complex fractures couldn't be classified according to this classification. The main purpose of this study was to evaluate the reliability of the Letournel and Judet classification system for acetabular fractures.

Material and methods: 10 acetabular fractures were analyzed among 17 orthopedic surgeons. The surgeons were asked to classify the fractures according to the Judet and Letournel classification. Their experience, the number of surgeries, and the incision type that the surgeon uses for the anterior part of the acetabulum were recorded.

Results: The overall interobserver agreement for the Letournel classification was found to be poor, with a Kappa value of 0.287. The Kappa value for interobserver agreement was 0.224 for plain radiographs, 0.293 for 2D-CT, and 0.321 for 3D-CT scans. There was no significant difference between the incision types used by the surgeons. The highest reliability was determined among the surgeons who operate on 10-20 acetabular fractures per year, with a Kappa value of 0.309.

Conclusion: This results revealed that the Judet and Letournel Judet classification is not sufficient to classify acetabular fractures because of unclassified fractures and the complex algorithm of the system. Level of Evidence III; Comparative Retrospective Study.

评估 LETOURNEL 和 JUDET 分类法的观察者间可靠性。
简介Judet 和 Letournel 分类法是最广泛使用的髋臼骨折分类系统。一些复杂骨折无法按照该分类法进行分类。本研究的主要目的是评估 Letournel 和 Judet 分类系统对髋臼骨折的可靠性。要求外科医生根据 Judet 和 Letournel 分类法对骨折进行分类。他们的经验、手术次数以及外科医生在髋臼前部使用的切口类型都被记录在案:Letournel分类法的总体观察者间一致性较差,Kappa值为0.287。平片的观察者间一致性 Kappa 值为 0.224,2D-CT 为 0.293,3D-CT 扫描为 0.321。外科医生使用的切口类型之间没有明显差异。每年对 10-20 例髋臼骨折进行手术的外科医生的可靠性最高,Kappa 值为 0.309:这一结果表明,Judet 和 Letournel Judet 分类法不足以对髋臼骨折进行分类,因为存在未分类的骨折和该系统的复杂算法。证据等级 III;比较性回顾研究。
