A case of subcutaneous rupture of the neurovascular bundle under the collarbone

On 23 / III 1923, a 7-year-old boy B. with complete paralysis of his right arm was delivered to the department. The father who brought the boy told the story of the misfortune that happened in October 1922. The boy was instructed to lead the horse. Holding her on the rein, he went to the indicated place. The halter was wrapped around the arm. Suddenly the horse, frightened of something, jerked violently back and rushed to the side, dragging the leader with it. The boy followed her a few steps and was then raised without memory. Immediately after that, his right arm was severely swollen. The tumor was especially large on the neck and in the upper part of the shoulder it did not have a blue-purple color. After being ill for several weeks, the patient began to feel better: the tumor began to subside, and the skin began to take on a normal color. Then it was noticed that, although the hand looks healthy, it has lost its ability, movement and sensation.
