Sports Injuries in Children: Prevention, First Response, and Recovery

If your child has just been hurt, skip to what to do in the first hour. If something looks badly wrong — a limb out of shape, bone through skin, a child who will not wake up properly, or neck pain after a collision — stop reading and call 911.

Everything else here is the part that matters between injuries, and there is one thing worth knowing before the rest of it.

Children are not small adults, and their injuries are different

A growing child’s bones have not finished. At the end of each long bone sits a growth plate — a band of cartilage that is weaker than the ligament next to it. In an adult, force through a twisted ankle tends to tear the ligament, which is a sprain. In a child, the same force often fails at the growth plate instead.

That has a practical consequence parents are rarely told: a child’s “bad sprain” that is still painful over the bone a few days later deserves an examination, even though the same injury in an adult would just need time. Growth plate injuries are usually straightforward when they are found and treated. Missed ones are the small number that go on to affect how a bone grows.

The other difference is subtler. Children’s bones bend before they break, so a fracture can be a buckle or a crack rather than a clean snap — painful, real, and entirely capable of looking like a sprain from the outside.

The injury nobody reports

Ask a parent about sports injuries and they picture a collision. Most of what we see is the other kind: overuse. The same motion, thousands of times, without enough recovery. Pitching. Swimming. Gymnastics. Distance running. Tennis.

Overuse injuries are easy to miss because they arrive politely. They present as “it only hurts when I play,” which sounds like nothing, and which a child who loves their sport will happily not mention. By the time it hurts at rest, the child has usually been hurting for weeks.

Three things reduce overuse injuries more than anything else, and all three are scheduling decisions rather than medical ones:

• At least one full day off per week from organised sport, and a longer break of two to three months a year from any single sport — not from all activity, just from that one motion.
• Roughly one weekly hour of organised training per year of age as a ceiling. A ten-year-old training fifteen hours a week is at real risk, however much they want to.
• Not playing the same sport in two leagues at once. This is where the hours quietly double, and it usually happens without anyone doing the arithmetic.

The Arizona version of this problem is worse than the national one. Outdoor sport here runs all year. Where a snowbound state gets an enforced off-season, a Phoenix-area child can play club soccer through January and travel ball through July with no natural break at all. The rest period other children get by accident, ours have to be given on purpose.

Heat is an injury multiplier

August football practice in Gilbert is not the same activity as August football practice in Ohio, and treating it as such is how children get hurt here.

Dehydration degrades coordination and reaction time before anyone feels unwell, and a tired, slow athlete in the fourth quarter of a 105-degree evening is a child more likely to land badly. Heat also masks injury: a child who stops because they are hurt looks exactly like a child who stops because they are hot.

Water before, during, and after — not only when thirsty, because thirst arrives late. Practice scheduled around the heat rather than through it. And a clear rule that stopping is allowed. We have written the full version of this separately in our guide to heat safety in Arizona.

Equipment, briefly

Protective gear works, and it works considerably less well when it does not fit. A helmet borrowed from an older sibling, shin guards that slide, cleats from two seasons ago — these are the common ones. Mouthguards prevent dental injuries. Wrist guards genuinely prevent the fractures that skateboards and scooters cause.

One honest caveat, because overstating it does harm: a helmet reduces skull fracture and severe brain injury; it does not prevent concussion. A child in a correctly fitted helmet can still get a concussion, and parents who believe otherwise are slower to recognise one.

Concussion

A concussion is a brain injury caused by force to the head or body. It does not require a blow to the head, it does not require losing consciousness, and it does not show up on a standard scan — which is why the diagnosis rests on symptoms and on someone noticing them.

Signs in the moment: appearing dazed or stunned, confusion about the score or the play, clumsiness, slow answers, a blank look, any loss of consciousness, or a personality change that teammates notice before adults do.

Signs in the hours and days after: headache, nausea, sensitivity to light or noise, dizziness, feeling foggy, trouble concentrating, sleeping more or less than usual, irritability or sadness that is out of character. In younger children it often looks like unexplained fussiness, a change in play, or a child who simply will not settle.

The rule that matters: a child suspected of a concussion comes out and does not go back in that day. Not after a rest, not for the last few minutes, not if they insist they are fine. A second impact before the first has healed is the mechanism behind the rare catastrophic outcomes, and it is entirely preventable by sitting the child out. When in doubt, sit them out — there is no version of this decision where being cautious causes harm.

Go to an emergency room for a headache that keeps getting worse, repeated vomiting, seizure, weakness or numbness, slurred speech, one pupil larger than the other, increasing confusion or agitation, or a child who is unusually difficult to wake.

Recovery is a short period of relative rest — a day or two of reduced screens, schoolwork, and activity — and then a gradual, staged return to learning first and to sport second. Prolonged darkened-room rest was standard advice for years and is no longer recommended; it delays recovery rather than speeding it. Most children recover fully within a few weeks. Returning to play requires being symptom-free through each stage, and written clearance before a return to play is standard practice in Arizona youth sport — ask your school or league exactly what they require, because it varies. We provide that clearance, and we would rather do it properly than quickly.

Fractures and what looks like one

You cannot reliably tell a fracture from a bad sprain by looking, and neither can we — which is what X-rays are for.

Suspect a fracture when there is deformity, when the child cannot bear weight or use the limb at all, when swelling comes on fast and hard, when pain is directly over bone rather than over soft tissue, when there is numbness or tingling below the injury, or when a “sprain” has not improved in a few days.

Go straight to an emergency room for visible deformity, a bone breaking the skin, an injury where the limb below it is pale, cold, or numb, an obvious dislocation, or a suspected break of the thigh, hip, skull, or neck. Do not try to straighten anything. Support the limb as it lies, keep the child still, and go.

Everything short of that we can see, examine, and image, and most childhood fractures heal completely. Children remodel bone far better than adults do — which is the one genuine advantage of being small.

What to do in the first hour

For the ordinary sprain, strain, and knock:

1. Stop playing. Not “finish the game.” The single most common way a small injury becomes a big one is continuing on it.
2. Support and rest it for the first day or two — enough to let it settle, not enough to stiffen. Prolonged immobilisation is no longer the goal.
3. Ice for comfort, wrapped in a cloth, fifteen to twenty minutes at a time, during the first forty-eight hours. Never directly against skin.
4. Compress with an elastic bandage if it helps, snug and not tight. Numbness, tingling, or colour change below the wrap means it is too tight.
5. Elevate above the level of the heart where you can.
6. For pain, children’s ibuprofen or acetaminophen at the dose for their weight. Never aspirin for a child or teenager — it carries a risk of Reye syndrome.
7. Then move, gently and early. Return to normal use as pain allows, and to sport in stages rather than all at once.

If they cannot use it at all, if the pain is severe, or if nothing has improved in two or three days, have it looked at.

Call us if

• A joint injury still hurts over the bone after a few days, or the child is still limping
• Pain that only appears during a specific sport and keeps coming back — this is the overuse pattern, and it is much easier to fix early
• Swelling that is not settling, or a joint that gives way, locks, or catches
• Any suspected concussion, including a mild one, and any concussion symptom that is not improving after a week or two
• Return-to-play clearance is needed, for a concussion or any other injury
• Your child is in pain often enough that you have started treating it as normal
• A pre-season sports physical is due. Worth knowing: a sports physical is not a substitute for a well-child visit. It clears a child to play and is a narrower examination with a different purpose. If both are due, book them together and we will do both properly.

Go to an emergency room for

Visible deformity or a bone through the skin · a limb that is pale, cold, or numb below the injury · loss of consciousness · a head injury with worsening headache, repeated vomiting, seizure, or confusion · neck or spine pain after a collision · an injury to the head or abdomen in a child on a blood thinner · difficulty breathing after a chest impact · a child who cannot be woken normally.

The part that is not medical

Children stop reporting pain when the adults around them treat playing through it as a virtue. A child who believes an honest “my shoulder hurts” will cost them a place on the field will stop saying it, and the injury we then see is bigger than the one we would have seen.

Almost every serious youth sports injury we treat had a smaller, quieter version of itself a few weeks earlier.
