title: [Theory of traction. Determination of the optimal arrangement of metal in the dorsal traction of an olecranon fracture].
abstract: This is the analysis of external forces acting on the elbow joint and their influence on the appearance of bending forces, shearing forces and tensions along the ulna and their alterations with fractures of the olecranon. The influence of flexor muscles on the fracture site is being evaluated too. The fracture of the olecranon is being defined by means of statics. All disadvantages of a dorsal tension band i.e. uncertainty to neutralize all forces acting at the fracture site adequately, irregular interfragmentary compression, creation of unwanted stearing forces and moments, rest on its excentric localisation. The optimal distribution of hard ware is being evaluated.
