Summary:We calculated the inter-observer variation in Garden's classification for femoral neck fracture. Forty radiographs were evaluated using Garden's classification by five orthopedic surgeons. The agreement rate between observers and Kappa statistics were assessed. The agreement rate was 37.5%, and Kappa value was 0.51. When the fracture was classified into two stages; non-displaced (Stage I, II) or displaced (Stage III, IV), the agreement rate was 80.0%, and Kappa value was 0.80. Eight cases did not agree in the two stages. Seven of eight were cases of complete fracture with valgus position or with slight displacement.
