The Neer four-segment classification system for proximal humerus fractures is shown. This diagram includes the valgus impacted four-part fracture (A) and the classic displaced four-part fracture (B).

The four-part fracture occurs in two forms. In the (A) classic four-part fracture, the articular surface of the head is no longer in contact with the glenoid. In the (B) valgus impacted fracture, the humeral head is driven down and the tuberosities splay out. (Reprinted with permission from Elsevier from Neer CS 2nd. Four-segment classification of proximal humeral fractures: purpose and reliable use. J Shoulder Elbow Surg. 2002;11:389–400.)

There is a correlation between functional outcome scores and the Neer classification system for patients undergoing open reduction internal fixation. The Constant score decreases with increasing fracture parts. (Reprinted with permission from Elsevier from Sproul RC, Iyengar JJ, Devcic Z, Feeley BT.
