The diaphragm is the main respiratory muscle. It has the most significant function in respiratory excursions and the ability to maintain the negative thoracic pressure. Diaphragm injuries are relatively rare and they are the result of blunt or, in our conditions less often, penetrating thoracoabdominal trauma. (The ratio of blunt traumas to penetrating ones is 9:1). The diaphragmatic injuries in blunt injuries occur as a result of the increased pressure gradient between the pleural and peritoneal cavity [1]. The first description of traumatic diaphragm rupture is ascribed to Sennertus from 1541. Other sources award the primacy to the French royal surgeon A. Pare in 1579 [2]. It is similar to the primacy of the surgical repair of diaphragmatic injuries. Rioffi in 1886 [3] versus Naumann in 1888 who operated on traumatic herniation of the stomach into the left chest cavity [2]. Diaphragmatic injury diagnosis is difficult even today [4]; up to 10-50% of cases are not recognized in time. Left-sided traumatic lesion of the diaphragm occurs in 80-90% of cases. Our paper focuses on the specifics of right-sided diaphragm ruptures where the protective ability of the liver is probably reflected.
