Justiniano worked in a poultry-packing plant where his job was cutting open chickens and stripping out their visceral organs. After work, he typed for long hours on his computer keyboard, writing a book about his work in the plant. Soon, his wrist and hand began to hurt whenever he flexed it, and he began to awaken at night with pain and tingling on the thumb half of his hand. What condition did he probably have?

Hello, everyone and welcome to today's video. So professional pianists are more likely to develop which of the following conditions as answer to is a, we have carpal fracture. B, carpal tunnel syndrome, C carpal bone dislocation. The all of the above, let's begin by looking at our answer choices. A and C carpal fracture, carpal bone dislocation. Well, a professional pianist, if we think about it, most of the injuries that are going to be presented are going to come from constantly having to play the piano. Now, the reason why we're looking at A N C together is that we have fractures and these locations, these are going to be arising from certain traumatic events such as a fall or an accident that are going to cause these carpal fractures and carpal bone dislocations. However, these are not going to arise from constantly playing an instrument such as the piano and therefore, we're going to cancel them out and then we have the carpal tunnel syndrome. Well as it turns out, this carpal tunnel syndrome occurs when the arrangement of the bones in the hand is such that the carpus is concave anteriorly and a ligament is going to rove over this concavity forming their notorious tunnel that we call it. Now, this is going to cause or is going to start compressing the median nerve which is going to cause this tingling and numbness of the areas served. And this is going to be very much seen in professional pianists because of the constant use or the constant playing of this instrument. Therefore, answer choice B Carpal TUNEL syndrome is going to be the final answer for this question. I really hope this video helped you and I hope to see you on the next one.
