[Fritz König (1866-1952): pioneer of osteosynthesis and his influence on traumatology].

Fritz König (1866-1952) was 1918-1935 ordinary professor of surgery at the University of Wuerzburg. A main interest of his work was the technique and indication of osteosynthesis. Since 1900 he investigated methods (wire suture, intra- and extramedullary splint, external fixator, plate) and materials (ivory, steel; wire, screws). All his life he aimed to standardize the technique of osteosynthesis, to work out and spread clear indications for the surgical treatment of fractures, and to carry his point against the resistance of the social accident insurance caused by bad results of a lot of surgeons. His importance is not based on the invention of a great deal of instruments but on his endeavour for the fundamentals of osteosynthesis.

[Inguinal hernia in old age].

By retrospective analysis of the medical records from 1978-1985, the rates of incarceration, postoperative complications and lethality were determined with particular consideration of elective and emergency operations. The proportion of over 60 year old patients with inguinal hernia was 37.3%. The rate of incarceration in these patients (9.8%) was more than five times as high as in patients under 60 years old (1.8%); with increasing age, it rose from 3% to 36%. The Bassini technique predominated in the surgical treatment of the hernia. The rate of postoperative complications was 7.5%, wound infections (3.35%) and hematomas (3.07%) being the most frequent. Four patients died postoperatively, mostly of pulmonary complications; this corresponds to a lethality of 1.1% as compared to this corresponds to a lethality of 1.1% as compared to 0% in patients under 60 years old. Emergency operations in incarcerated hernia display a lethality (5.71%) which is more than nine times as high as in elective operations (0.62%). The indication for surgery is hence to be established rather extensively in the elderly, since the danger of incarceration rises.

[Pseudarthrosis of the scaphoid bone and carpal instability. Correlations--development--consequences].

In combination with its ligamentous connections, the scaphoid bone represents an essential stabilizing factor within the wrist. This stabilizing function disappears after trauma causing a displaced fracture of the scaphoid bone or extensive rupture of ligamentous structures fixing the scaphoid in its position. Hence carpal instability results, detectible radiographically by alteration of defined wrist angles. Since this is so, one might suppose that, together with other wellknown reasons, carpal instability would be of great importance in the development of a scaphoid nonunion. However, after evaluation of 76 cases, a scaphoid nonunion with carpal instability was found in only 27.6%. Moreover, surgical treatment of the scaphoid nonunion alone does not correct the abnormal wrist angles. Despite this observation, we do not consider simultaneous ligamentous repair to be necessary, because few problems remained after bony healing in such cases.

[The Braun apparatus for mixed ether-chloroform anesthesia. A contribution to the early history of combination anesthesia].

The Braun ether-chloroform vaporiser was very frequently used during the first fifty years of the 20th century, mainly in the German speaking region. This primacy was principally involved by the simple management, the universal possibilities of application and the "expedient" combination of ether and chloroform: this term means the differential employment of these two substances for conducting individual anaesthesia. Heinrich Braun had published his method after extensive experimental studies, here briefly referred to; further reasons for the considerable success of the apparatus are discussed.
