Fig. 1.1 The average humeral neck angle is 130°. The superior aspect of the articular surface is 8 mm above the greater tuberosity. Average retroversion values are 18–33° The proximal humeral…

Fig. 5.1 Insufficient stability of the fixation with pinning and example of early loss of reduction Fixed-angle locked plates are very popular at the moment and have become a kind…

Fig. 9.1 (a and b) Radiograph 1 year (a) after a non-displaced proximal humerus fracture in an active 52-year-old female. Fracture appears healed on the film, but the patient complains…

Fig. 6.1 Two-part surgical neck fracture with medial calcar comminution and head in varus The plate has small holes for temporary stabilizing wires to be placed through it into the…

Fig. 10.1 Proximal humerus nonunion with varus collapse noted after open reduction and internal fixation with screw penetrance into glenohumeral joint. Laboratory workup was equivalent and decision for two-stage procedure…

Fig. 8.1 (a and b) AP and lateral radiographs of a fracture dislocation in a 70-year-old male. (c and d) 3D reconstruction images of a four-part proximal humerus fracture demonstrating…

Fig. 2.1 Vascular network of the proximal humerus With their close proximity to the proximal humerus, neurologic structures are at risk for injury after proximal humerus fracture. Neurologic injuries generally…

Fig. 7.1 When setting up the patient, the ability to obtain adequate images should be confirmed before draping. The position of the C-arm shown here permits easy images without significant…
