[Biomechanic examination of rib plates (author's transl)].

The aim of a rib osteosynthesis is entirely the physiological restoration of the chest wall compound. Elastic rib clamps are very suitable for this purpose; rigid plates hinder the breathing movement of the ribs and often work loose. An examination meant to evaluate the best form of osteosynthesis has to consider these aspects. Crush tests of rib osteosyntheses, however, are not representative for the respiratory physiology of a stabilized thorax.
