After a Cycling Crash: What Needs the ER, What Needs an X-Ray, What Needs a PT

First: the list that goes to emergency care now

Crashes scramble judgment — adrenaline is a terrible triage nurse. If any of these are true, the ride is over and the destination is urgent medical care, not home:

• Your head hit anything — pavement, car, bars — with confusion, memory gaps, worsening headache, vomiting, or a cracked helmet. Helmet research is clear that lids dramatically reduce serious head injury — but a damaged helmet means forces got through, and concussion evaluation is same-day, no exceptions.
• Chest pain or trouble breathing after hitting the bars or the ground (ribs and worse need eyes on them).
• An obviously deformed limb, a joint that won't move, or bleeding that won't stop with pressure.

None of those? Then the next question is bones that hide.

The two X-rays cyclists skip — and regret

The collarbone. The clavicle is cycling's signature fracture: a shoulder-first landing, a snap or deep ache at the collarbone, pain lifting the arm. It needs an X-ray — most heal without surgery, but that decision (sling versus fixation) depends on what the image shows, and it belongs to an orthopedist. A "bad bruise" treated with toughness for two weeks can become a much longer story.

The scaphoid. Brace a fall with an outstretched hand and the small bone at the base of your thumb takes the hit. Scaphoid fractures are infamous for feeling like a mild sprain, being ignored, and then failing to heal — a missed one can mean months of casting or surgery later. Tenderness in the "snuffbox" hollow on the thumb side of the wrist = X-ray, even if your grip feels okay. The lesser version of this story is a wrist sprain; the X-ray is how you find out which one you have.

Also on the watch list: a painful bump at the point of the shoulder (the AC joint — the "separated shoulder" pattern) and any hip pain that makes weight-bearing hard.
