Q: Abstract: A 53-year-old male, while lifting a heavy object, suffered a rupture of the distal biceps brachii tendon. Due to extremely well developed musculature, the patient had retained surprisingly good powers of supination and flexion, albeit decreased in comparison to the other side. During the following operation, the torn tendon was sutured to the tendon of the brachial muscle, with good results. In this type of patient, the mentioned operative procedure is preferable, rather than the more hazardous reinsertion of the tendon, which should only be used in cases with a significant loss of supination and flexion power.

Q: Abstract: In this report, 11 cases of angiosarcoma of the head and neck are reviewed. The patients ranged in age from newborn to 78 years; mean age was 64 years. There were eight men and three women. Sites of involvement included the scalp and forehead, cheek, nose and ethmoid sinuses, neck, and mandible. Surgery was the primary method of treatment. The 2-year survival rate was 50% (5/10) and the 5-year survival rate was 22% (2/9). Regional metastases were seen in 18% (2/11). We found that the tumors were poorly circumscribed and spread horizontally within the dermis for considerable distances, especially in the scalp. Total surgical excision using frozen section control before reconstruction may offer the best chance for control of disease.

Q: Abstract: Off-road vehicles have attained growing popularity, expanding markets and increasing rates of associated injury, especially among young people. In 1984-85, 148 patients were treated at the Children's Hospital of Eastern Ontario, Ottawa, for injuries suffered in off-road vehicle accidents. The average age of the patients was 14 years. Soft-tissue injuries occurred in 33 patients, 21 of whom had severe injuries. There were 179 fractures in 133 patients. One patient died as a result of his injuries. The most common mechanism of injury was losing control of and tumbling from the machine. Seventeen patients were struck by their own vehicles, and 39 collided with objects such as cars, trees or people. The health care costs of these accidents are no less serious than the concerns for the appropriate legislation to protect consumers, particularly the young.

A:
Injuries associated with off-road vehicles among children.
