The 'Bible bump' got its name from people striking these wrist cysts with a heavy book — a folk remedy that sometimes works and usually doesn't need to be attempted at all. Here's what actually determines whether one needs treatment.

Numbness in the ring and pinky finger gets blamed on 'sleeping wrong' far longer than it should. The nerve involved doesn't distinguish between a bump on the funny bone and months of chronic compression — and by the time there's real weakness, recovery gets a lot less reliable.

Pain at the base of the thumb usually starts small — a jar lid, a car key, a firm handshake. For a lot of patients it's the most common form of hand arthritis, and it's also one of the most treatable if it's caught before it limits daily function.

A fall onto the thumb usually gets waved off as a sprain. Enough of the time it's actually a torn ligament — and the two look identical for the first 48 hours. Here's the exam that tells them apart, and why the window to fix it matters.

Persistent swelling around a finger joint can mean very little or quite a lot depending on the details. Some of those details are time-sensitive in ways that are not obvious from the outside — including one that constitutes a same-day surgical emergency.

Carpal tunnel release is performed over 500,000 times per year in the United States. It is also one of the most poorly explained procedures in advance — which creates unnecessary anxiety and unrealistic expectations about recovery. Here is the honest version.

Morning hand stiffness is one of the most normalized symptoms in clinical medicine. It is also one of the most diagnostically important — and the single most useful question is one most physicians never ask: how long does it last?

Dupuytren's contracture is progressive, genetic, and one of the most fascinating conditions in hand surgery. The Viking disease connection, the table-top test, and why treatment is most straightforward before the finger is completely bent down — not after.

Not all hand numbness is carpal tunnel. Thoracic outlet syndrome is one of the most frequently missed diagnoses in upper extremity medicine — overlapping with carpal tunnel, cervical disc disease, and rotator cuff pathology. The pectoralis minor connection and the self-test you can do right now.

One of the most common concerns from patients who need a brace but are reluctant to wear one. True disuse atrophy requires prolonged near-complete immobilization — not a wrist brace worn during symptomatic activities. The correct use case, and when the brace becomes the problem.

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.

Phalen's test — the classic prayer-hands maneuver — has a false negative rate of roughly 25%. Durkan's compression test cuts that number significantly. Here's the technique, what a positive test means, and why this is the test I rely on in the clinic.

"If you can move it, it's not broken" is wrong. Movement tells you whether the tendons are working — not whether the bone is intact. Here's what actually tells the difference, and the mallet finger window you cannot afford to miss.

We call it a FOOSH — Fall on an Outstretched Hand. Pain level immediately after impact is a terrible predictor of fracture. Here's what actually tells you which category you're in — and the anatomical snuffbox test every outdoorsperson should know.

The four-stage progression of ulnar nerve compression at the elbow — and when the window for conservative treatment starts closing. Includes the Finkelstein test and a stage-by-stage breakdown of what symptoms mean at each point.
