Children often break their hands due to excessive activity. This is the injury that parents seek medical attention for. Running outside, playing tag, sports, and natural curiosity are all causes of falls on an outstretched hand and wrist fractures.
If the arm isn't deformed, it can be difficult for parents to determine what kind of injury their child has sustained. But there are signs to look out for.
The first symptom is a sharp pain that intensifies when trying to bear weight on the palm or make a fist. Rapidly increasing swelling and pain in the wrist make movement difficult. If there is deformity (the hand appears crooked or an abnormal protrusion is visible under the bone), this is a clear sign of a displaced fracture.
With a bruise, the pain subsides after a few hours, and joint mobility remains. With a fracture, lightly tapping your fist or elbow will cause the pain at the site of the injury to increase sharply.
For clarity, a comparison table of injury signs is provided:
| Sign | Wrist contusion | Sprained ligaments | Fracture |
|---|---|---|---|
| Pain | Moderate, gradually subsiding | Moderate or severe | Severe, sharp, "throbbing" |
| Swelling | Minor, localized | Moderate | Severe, rapidly increasing |
| Deformity | Absent | Absent | Often visible visually |
| Movement | Slightly limited | Painful, but possible | Severely limited or impossible |
| X-ray | Does not reveal bone pathologies | Shows bone integrity. | Required to confirm diagnosis. |
You should seek medical attention in the following situations:
Treating a wrist fracture also involves first aid.
After the injury, you should:
Do not attempt to reset the arm yourself! You can damage nerves and blood vessels. Do not allow the child to endure pain and do not use warming ointments.
If, after applying a cast, the child's fingers become swollen, turn blue, or complain of unbearable pressure inside the cast, return to the emergency room immediately. This may be a sign of soft tissue compression, which can lead to necrosis.

What is a wrist fracture and why does it require special attention in children?
This is an injury to the lower portions of the radius and ulna. A child's wrist fracture should be treated by a traumatologist. However, before beginning treatment, the doctor must conduct a diagnosis. Errors during the first aid phase can lead to lifelong limitations in hand function.
Characteristics of a child's bone and growth plate
Falls on an outstretched hand during active play, scootering, or sports often lead to skeletal injuries. Treating a child's wrist fracture requires a special approach, as the child's body is constantly developing, and any error in treatment can impact hand function in the future.
What are the most common wrist injuries?
The growth plate is the most vulnerable area. If a child's wrist fracture affects this area, there is a risk of premature closure of the growth plate, which can lead to limb shortening or deformity.
Children are often diagnosed with "greenstick" fractures, where the bone breaks internally, but the thick periosteum holds the fragments together, preventing them from completely separating. Subperiosteal fractures or epiphysiolysis (bone displacement along the growth plate) are also common wrist injuries in children. The radius is more often affected than the ulna, as it bears the brunt of the impact during a fall.
Why you shouldn't delay a trauma examination
A fracture doesn't always result in a deformed limb. The hand may be perfectly straight, and the child may be able to move their fingers, but this doesn't mean their bones are intact.
A pediatric traumatologist examines the child, orders an X-ray, and makes a diagnosis.
