The procedures of preclinical management of chest injuries are presented. Emphasis is put on the different aspects of "acute thorax": sucking chest wound, pericardial tamponade, oligemic shock and open thorax. The primary acute management includes the chest tube, intubation, ventilation, pericardiocentesis and surgical management of penetrating chest trauma. The different in the literature are discussed.
The present work deals with the problem of abdominal injuries in polytraumatized patients. The results were obtained from a retrospective study of the records of 530 polytraumatized patients treated at the Central Hospital of the German Federal Armed Forces (Bundeswehr). In all, 193 of these patients had abdominal injuries. The overall mortality was 23.8% (n = 126): mortality among the patients with abdominal injuries was 26% (n = 50). Abdominal injuries alone led to death in 9.1% (n = 1), but mortality increased to 18.4% when at least one extra-abdominal injuries was also present. A combination of abdominal injuries and two or more extra-abdominal lesion led to a mortality rate of 27%. Mortality was found to be age- and sex-related: in young children and patients over 55 years (especially those around 70) mortality was 33.3%-72%. Among the cases with fatal outcome there was a female-to-male ratio of 3:2. The most common causes of death were: hemorrhage shock (62.3%), head injuries (37.7%), septicemia (8.1%), pneumonia, and ARDS (5.4% each). Within the last eight years we have used the following supplementary examination methods: computed tomography, peritoneal lavage, and ultrasonography. The retrospective study has shown that CT is not the examination of choice. The reliability with lavage and ultrasonography was approximately the same, but lavage was found to be more dangerous. Therefore, we abandoned lavage and used sonography only. However, we are of the opinion that any surgeon should use the examination method that has yielded the best results for him or her, to ensure the best possible outcome for the patient.

The present work evaluates the method of double-contrast arthrography. To this end, cartilage damage on femoral condyles and tibial joint surfaces was studied in 1566 retrospectively evaluated double-contrast arthrographies. Operation reports and histological results served as control. The results of our own experiments demonstrate that even isolated cartilage lesions as small as 1 mm in diameter can be visualized.
