[Fractures of the head of the radius in childhood (author's transl)].

In childhood fractures of the head of the radius are typical and frequent. Generally these fractures are in the metaphysis, but a few cases are in the epiphysis. In the follow-up of conservatively treated fractures of the radial head in childhood, the therapeutic alternatives are discussed. The therapeutic procedure must take into account the degree of fragment displacement. Fractures of type I and II according to Judet are treated conservatively, predominantly by means of exact reduction and fixation in a plaster cast. If reduction fails for type III, however, type III and type IV fractures must be operated on at once for sufficient results.

[Fractures of the proximal and middle-third of the lower arm in childhood (author's transl)].

53 children with fractures of the proximal or middle third of the lower arm and who were treated conservatively have been reviewed between 5 and 13 years after the accident. In 23% of the patients with fractures of the middle third of the arm, the results were unsatisfactory or poor. As the spontaneous ability correct in the intermediate third of the forearm is apparently less than in the proximal and distal thirds close to the epiphysis an axially corrected reduction should be aimed at in all cases. If this cannot be achieved by conservative means, then surgical intervention is necessary even in children.

[Technique and technical blunders in grafting of large skin defects on extremities and joints with mesh-graft-II-dermatoma after Tanner-Vanderput (author's transl)].

The indication and surgical procedure of mesh skin grafting with mesh graft dermatoma II after Tanner-Vanderput concerning avoidable failures are shown. In order to avoid therapeutic complications of skin grafting in extremities it is of great importance to have a well granulating transplantation ground and to spread out the mesh graft equally. Even in regions of joints good results can be achieved.

[Reaction of articular cartilage to subchondral defect filling with autologous cancelous bone, Kiel's bone chips and bone cement].

Equally sized subchondral osseous defects were produced in 30 adult rabbits. The defects were filled with autologous cancellous bone, bone cement, or macerated heterologous cancellous bone. Twelve weeks later those filled with autologous cancellous bone showed consolidation with preservation of the subchondral border line. There were no degenerative changes of the joint's cartilage. Filling with bone cement or heterologous cancellous bone, on the other hand, led to destruction of the joint's cartilage. The defects treated with heterologous cancellous bone had not reached osseous consolidation at that time. These results suggest that effective treatment of subchondral osseous defects can only be achieved by filling with autologous cancellous bone.

[On the problem of industrial accidents under drug influence (author's transl)].

Industrial accidents resulting from technical defects have decreased in the last eights because of improved safety precautions. In contrast, accidents resulting from "human error" are increasing steadily. Toxicological urine analysis for drugs--directed mainly at soporifics, sedatives, tranquilizers, and pain-relievers--on 84 patients involved in industrial accidents yielded the following results. 1. Drugs were identified in 44 patients (= 52%). 2. In 13.4 patients, more than one drug was identified (= 16%). 3. Only five of the 44 patients admitted on being questioned that they had taken drugs (= 10%). On the other hand, in a control group of 47 persons who and not suffered any accident, drugs were detected in 19 cases (= 40%). The results show that the physician will have to take into account that healthy and efficient persons, too, are very often likely to practise drug abuse. It must be considered probable that this helps to promote accidents. Medical prescription, especially of neuroleptics and psychotropics, as well as of sedatives, should be practiced more.
