[Classification of fractures of the proximal end of the humerus following prognostic and therapeutic aspects].

The classification of the proximal humeral fractures according to the four-segment concept of Neer has proven to be very useful. It not only considers the fracture itself but also lesions of the soft tissue. Adapting Neer's concept we propose a modified classification of the proximal humeral fractures which we believe is clearer and more practicable. This classification is illustrated by means of drawings and typical roentgenograms. The description of the different fracture-types includes the mean characteristics such as fragment-displacement, status of the rotator cuff and blood circulation to the head segment.
