Abstract

Aim: To determine the Inter & Intra-observer Agreement in Assessment & Classiþcation of Non-unions of fractures based on Radiological appearance. Methods: X-rays of 100 adult patients with established non-union (NU) were selected by random sampling, excluding cases with poor quality x-rays. Common denominators of various classiþcation/assessment systems were selected for study. Observers were selected in 3 categories (2 in each): Senior Limb Reconstruction specialist, Musculoskeletal Radiologists & senior trainees. 6 weeks were allowed between the 2 sets of observations.

Data was analysed by calculating kappa coefþcients (95% CI) Results: Radiologists were unable to comment on vascularity.

Conclusion: Agreement in common denominators except hypertrophic/atrophic NU is poor. Radiographic analysis of non-union remains poor indicating the need for further study to see whether identiþable diagnostic, therapeutic & prognostic features exist
