Athletic Training Practice Exam

A tall basketball player presents with an arm span greater than his height and a protruding sternum. What condition might he have?

1. Paget's disease

2. Milch disease

3. Marfan syndrome

4. Addison's syndrome

The correct answer is: Marfan syndrome

Marfan syndrome is a genetic disorder that affects the connective tissue in the body, leading to a variety of skeletal, cardiovascular, and ocular manifestations. In individuals with Marfan syndrome, characteristics often include tall stature, long limbs, and a greater arm span compared to height, which fits the description of the tall basketball player in the scenario. The protruding sternum is another common feature associated with the skeletal abnormalities seen in this condition. These distinctive physical traits arise due to the way connective tissues are affected, causing elongation and overgrowth of bones and affecting the development of the chest wall as well. The combination of an increased arm span and a protruding sternum strongly suggests Marfan syndrome as the underlying condition in this case, making it the most appropriate choice. This condition is particularly relevant in athletes, as it can influence their physical capabilities and may pose risks such as cardiovascular complications. Understanding the signs of Marfan syndrome can lead to better management and monitoring in sports settings.
