Indications The PENTA-plates for the angle-stable treatment of proximal humerus fractures. › dislocated and unstable fractures of the capitellum › 2-, 3- and 4-fragment fractures › reconstructible calotte fractures › pathological fractures › long proximal humerus fractures › pseudoarthroses › osteotomies Characteristics › indirect reposition › no uncovering of the fragment › high primary stability through angle- and length-stable screws › shaft holes in alternate position › screw position on the long plate flange converging by 5 degrees in order to avoid a longitudinal rupture of the shaft when treating long fractures › high stability in the osteoporotic bone › low dislocation rate under an unlimited active
