A Sports Medicine Perspective on Denard's Injury

If you want non-professionals to become readers, you should explain more of the terminology. You say what flexion is, but neither what interosseous muscles nor what lumbricals are. IME, you can get away with not defining terms that have easily accessible, easily understood definitions (i.e., by a quick Googling, as with 'flexion'), as well as with any terms that a reasonably intelligent reader can deduce the meaning of (e.g., obviously 'interosseous' means 'between bones'--but which bones? those of the forearm or those of the hand?). Don't assume readers are going to blow up the images and hunt around for the terms.

Why didn't Denard have the protective sleeve on after first injuring it?  Would that have helped vs Nebraska?

Enjoyed reading the article. Nicely done!

At first I thought the post was addressed to mgrowold.  After reading the post from the link, my only thought is it's too bad Denard can't regenerate as quickly as Dr. Who.

Lumbricals are adjunct finger flexors that originate from the stronger flexor digitorum profundus tendons themselves. The dorsal interossei are responsible for spreading fingers wide, so would affect properly positioning fingers for gripping a football.
Likely more importantly, the ulnar nerve innervates the ring and pinky finger flexor digitorum profundus, which flexes the metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints (grip), as well as the flexor digiti minimi brevis (another pinky finger flexor), and also the flexor carpi ulnaris, very strong wrist flexor (used in such actions when hammering or with follow-through throwing a football (but I'm not sure if that muscle already receives its innervation ahead of where Denard had his injured. Either way, good start to your blog but probably good to have other medically trained people proof for completeness and accuracy before disseminating information.
