Golfer's elbow and tennis elbow are the same pathological process — tendon degeneration from repetitive overload — on opposite sides of the joint. The rehabilitation principles are identical, the exercises are mirror images of each other, and yet medial epicondylitis gets a fraction of the clinical attention its lateral counterpart does.

Mallet finger is one of the most commonly undertreated hand injuries — not because it is complex, but because the window for non-surgical treatment closes quietly while people wait to see if it resolves on its own. It does not resolve on its own.

Trigger finger is a specific mechanical problem with a specific solution — and the sooner it is addressed, the simpler that solution tends to be. A corticosteroid injection resolves it completely in the majority of early cases. Do not normalize a finger that catches.

De Quervain's is not bad luck — it is a predictable response to a predictable loading pattern. The mechanics behind Mommy Thumb, Gamer's Thumb, and Fly Fisher's Wrist are identical. Understanding them changes how you think about prevention and when to act.

Why new parents, gamers, and fly fishermen all develop the same condition — the anatomy behind Mommy Thumb, Gamer's Thumb, and Fly Fisher's Wrist. Why cortisone works here when it doesn't for tennis elbow, and the treatment hierarchy that actually resolves it.

CMC arthritis vs. De Quervain's tenosynovitis — two conditions that hurt in the same neighborhood but require completely different treatment. The Finkelstein test and CMC grind test that tell you which one you're dealing with.

Tennis elbow has forty different treatments because none of them truly works — except one. Eccentric loading of the wrist extensors has genuine evidence behind it. Here's the protocol, why it works, and why your instincts about rest are wrong.
