The treatment of fractures of the distal humerus remains challenging due to the complex anatomy of the elbow joint. Satisfactory results can only be attained with the complete recovery of the function and stability of the joint. Open reduction and internal fixation following AO principles, therefore, represents the standard procedure for the treatment of distal humerus fractures. Unfavourable results can, however, not be avoided in all cases, especially if fractures are complicated by concomitant lesions of soft tissues, nerves or vessels.
