Question

a 30 year man sustains a left femoral fracture in a skiing accident, and his leg is placed in a cast. after several weeks of immobilization, you find that the left calf is half the size of the right calf. this change is likely due to which of the following? aplasia atrophy hypoplasia dystrophy hyalinosis

Answer 1

Atrophy
Explanation: Atrophy is the progressive degeneration of muscle or nerve tissue. When you wear a cast for multiple weeks and you’re not allowed to bare weight, your muscles tend to become weaker because you haven’t used it in a while. That’s why PT is recommended after a bone break.
