Fig. 2From: Reproducibility of the modified Neer classification defining displacement with respect to the humeral head fragment for proximal humeral fracturesLeft proximal humeral fracture of a 53-year-old man. The humeral head is displaced inferiorly with the other components staying together. The consensus of assessments is divided from 2-part fracture to 4-part fracture with the conventional Neer classification, but it is seen as a 4-part fracture with the modified classification. a Antero-posterior and scapular-Y views of plain radiographs. b Anterior and lateral views of 3-dimensional CT reconstructionsBack to article page
