Most people who have been in a car crash describe the moment the same way: a jolt, a grip tightening on the wheel, and a hand pressing against the dashboard or the door. The hands and wrists are often where those forces travel first. Because they are busy with everyday tasks, a small change in grip or wrist movement is easy to explain away. This article covers what the hands and wrists do during a crash, which details are worth writing down, and what an examination of the hands typically involves.
Why the hands take part in the impact
When a vehicle stops suddenly, the body keeps moving until a seatbelt, airbag, steering wheel or door slows it. Many drivers grip the wheel hard, and some brace an open palm against the dashboard or the center console. The wrist, thumb and fingers then carry part of that load. Passengers may brace against the seat in front of them or a grab handle. Even a collision at moderate speed can leave the hands tense and working harder than usual.
Details worth noting before your visit
Write down what your hands were doing at the moment of impact. Were both hands on the wheel at ten and two, or was one hand on the gear shifter, a phone, a coffee cup or a child's car seat? Note which side took the brunt of the stop, and whether you braced with an open palm or a closed fist. These details help an examiner understand the mechanics of what happened, which is part of an honest history. Keep the notes factual. Describe what you did, not what you think the result should be.
Also note which tasks feel different since the crash: turning a door handle, twisting a jar lid, typing, holding a phone for long stretches, or gripping the wheel on the drive home. Describe each one in plain words, such as 'the thumb side of my right wrist feels stiff when I lift a grocery bag,' rather than a single word like 'hurts.' Plain words give the examiner more to work with.
What a hand and wrist exam covers
An examination of the hands and wrists usually starts with a conversation about the crash and your daily routine, then moves to looking and touching. An examiner may compare both sides, look at the skin, check for tenderness along the bones and joints, and ask you to move each finger, the thumb and the wrist through their normal motions. You may be asked to squeeze the examiner's fingers, pinch between thumb and index finger, or hold your arms out straight. Each movement shows whether something feels different on one side than the other.
Because the wrist is made of many small bones and the thumb has its own joint structure, examiners often watch how the parts move together, not only the single spot that hurts. Tell the examiner about any new sensation, such as tingling, numbness, weakness or a catch when you move. Those details help decide what else to check. An examination is about gathering information so a plan can be made. It is not a verdict delivered at the door.
Keep a simple timeline
Many people notice hand symptoms later than other symptoms, because attention is pulled toward whatever feels most urgent right after a crash. Track when each change first appeared and how it shifts from day to day. A simple list works: the date, the activity, what felt different, and whether rest made it better or worse. Keep this list separate from your medical records and bring it with you. If you already have a note from the scene or from another provider, bring that too.
When to get looked at this week
Do not wait until a hand or wrist is hard to use before getting it checked. If you notice new weakness, numbness that spreads, a grip that suddenly feels different, or any change that worries you, contact a provider promptly. Sudden or severe symptoms, such as a hand that turns cold, pale or unusually swollen, need emergency care rather than a scheduled visit. For everything else, Missouri Injury Clinic in the St. Louis area examines people after collisions, including the hands and wrists, and the first visit is a chance to ask questions as well as answer them. Bring your notes, a photo ID, and a list of the medicines you take.
