Ficat's 1985 review presents the complete five-stage (0–IV) classification of idiopathic femoral head osteonecrosis. It introduces the 'silent hip' (Stage 0) concept and the functional exploration of bone (FEB) technique for preradiographic diagnosis. Outcomes of core decompression in 133 hips followed for an average of 9.5 years are reported.
