title: [Mechanical force exercised on the elbow joint in olecranon fractures (author's transl)].
abstract: Opinion is fairly unanimous on the need for surgical treatment of disclocated olecranon fractures. However, opinions differ regarding the mechanical backgrounds and practical application of the presently widely used tension wiring. The article attempts to clarify the picture of the forces involved in the humero-ulnar joint. Basing on the points of attack of these forces and on the influence of the ligamentum collaterale ulnare, the fractures are subdivided into three groups with individual demands on the respective fixation method and the permissible post-operative exercise therapy. Post-operative plaster immobilisation is not indicated in these cases.
