The first group consisted of 10 orthopedic surgeons with a minimum of 5 years of experience. The second group consisted of 10 orthopedic residents in their first two years of practice. Interobserver reliability and intraobserver reproducibility were assessed using Cohen’s kappa test.Results: None of the classifications achieved good – very good reliability levels. The Fernandez classification had a moderate and the others had a fair interobserver agreement kappa coefficient. All classifications had fair kappa intraobserver agreement although the Frykman and Fernandez classifications had better results.Conclusion: None of the classification systems were superior in terms of reliability and reproducibility. The reliability and reproducibility rates of all four classifications were insufficient.

Birinci grup en az 5 yıllık tecrübeye sahip 10 ortopedi cerrahından, ikinci grup ise uzmanlık eğitiminin ilk 2 yılı içerisinde olan 10 ortopedi asistanından oluşmaktaydı. Değerlendiricilerin kendi içindeki ve değerlendiriciler arasındaki uyumu Cohen’in kappa testi ile değerlendirildi. Bulgular: Güvenilirlik açısından hiçbir sınıflama sistemi iyi – çok iyi seviyesine ulaşamadı. Fernandez sınıflamasında orta diğer sınıflamalarda ise düşük düzeyde değerlendiriciler arası uyum mevcuttu. Frykman ve Fernandez sınıflamalarında diğerlerine göre daha iyi sonuçlar alınmış olsa da, tüm sınıflamaların tekrar edilebilirliği düşük seviyede kaldı. Çıkarımlar: AO, Frykman, Fernandez ve Universal sınıflama sistemlerinin güvenilirlik ve tekrar edilebilirlik özellikleri açısından birbirlerine belirgin üstünlükleri yoktur. Dört sınıflamanın da güvenilirlik ve tekrar edilebilirlik oranları yetersizdir. CR - Lill CA, Goldhahn J, Albrecht A, Eckstein F, Gatzka C, Schneider E.
