Question

In 1962 a boy while playing in a train yard had his arm completely cut off by a train. Surgeons reattched the arm by sewing nerves, muscles and vessel back together. The boy was told that he would eventually regain use of his arm but never to the extent of pitching a baseball. Do you agree or disagree with this information. Why?

Answer 1

I disagree.

Step-by-step explanation:

Muscles tend to have a faster metabolism than other kinds of tissue, so a severed arm will deteriorate quicker than a finger. To reattache an arm we need to restore the blood flow by reconnecting the arteries. The procedure only works if the severed tissue is alive. It is also necessary to reattach the veins or the blood will not be able to flow out of the damaged arm.

Without a conduit for outflow the arm would swell and had a tissue damage.

When it comes to clean cut situation, the surgeons often remove some tissue to make the appendage shorter.

Since the surgeons reattached the boy arms by sewing nervers, muscles and vessels back together, it is unlikely that he would eventually regain use of his arm. I even think that the boy might have lost his entire arm.
