Splinter

life science Maturity 11-13 Next article →

A splinter is a small piece of an object that gets stuck in your body. To be called a splinter, the object must go into your tissue and stay there.

These tiny objects can cause pain right away. This happens because they damage your flesh and muscle as they enter. They can also bring bacteria into your body. This can lead to an infection if the object is not removed. Most people feel the pain when the sharp object breaks the skin layer.

Splinters work by moving through the layers of your skin. The object first pierces the top layer, called the cutaneous layer. It then settles in the layer underneath, known as the subcutaneous layer. Sometimes, a splinter can go even deeper into the muscle. In very rare cases, it might even reach the bone. Some splinters, like those made of hair, can actually move through your body. This movement can cause more irritation and damage to your tissues.

Scientists and doctors group splinters into two main classes. The American Academy of Family Physicians uses these official names. The first class is biological splinters. These come from living things and include wood, bone, teeth, or hair.

The second class is nonbiological splinters. These are made of things like glass, metal, plastic, or even pencil graphite. You might also get a splinter from a fishhook or a sea urchin spine. Some people even get splinters from grenade shrapnel.

There are many ways to find a hidden splinter. Doctors might use projectional radiography, which is a type of X-ray. This can find metal, glass, teeth, or even some wood like cactus thorns. They can also use medical ultrasonography, which uses sound to see inside you. This tool is great for finding small wooden splinters near the surface. If a splinter is near a bone, a CT scan might work better.

Doctors use these tools to see exactly where the object is hiding.

Removing a splinter must be done carefully to stay safe. One way is the elliptical excision technique. In this method, a doctor cuts a small oval shape around the splinter. They then remove that piece of tissue to take the object out. For fishhooks, doctors might use the string technique. They loop a string around the hook to help pull it out safely.

If a splinter stays in for more than two or three days, you should see a doctor. This helps prevent serious problems like an infection.
