BACKGROUND: The purpose of this study is to test the hypothesis of the new classification system of distal end radius fractures (Barzullah working classification) proposed by one of the author in a prospective cohort study, among the orthopaedic residents.
METHODS: The initial post-injury radiographs of 300 patients with distal radius fractures in a tertiary centre were classified by two junior residents (JR1 and JR2) and two senior residents (SR1 and SR2) in the emergency department over a period of two years. The collected data was analysed statistically by using Cohan's kappa for measuring Intraobserver reproducibility and Fleiss kappa for measuring Interobserver agreement.
RESULTS: The mean kappa value for Interobserver agreement was 0.53 (moderate agreement) at the end of one year and the mean kappa value at the end of study period was 0.64 (substantial agreement). The mean kappa value for Intraobserver reproducibility of JR1 was 0.45 (moderate agreement), JR2 was 0.39 (fair agreement), SR1 was 0.62 (substantial agreement) and SR2 was 0.67 (substantial agreement).
CONCLUSIONS: Barzullah working classification of distal radius fractures presented in this study has good characteristics compared to those of already studied classification systems among orthopaedic residents.
