External fixation is when a doctor puts a special frame on your arm or leg to help fix it if it is broken or injured. This frame works like scaffolding, which is a structure that helps to support a building while it is being built or repaired.
The doctor will first use surgical screws or pins to attach the frame to your bones. These screws are very strong and are placed inside your bone, so you won't be able to feel them. Once the screws are in place, the doctor will attach metal bars or rods to the screws, creating a frame around the injured area.
The frame will keep your broken or injured bones in place and help them grow back together. It will also prevent your arm or leg from moving too much, which can be very painful and make the injury worse.
The doctor may adjust the frame from time to time to make sure it is still in the right place and to encourage your bones to heal properly. Once your bones have healed, which can take several weeks or months, the doctor will remove the frame using a special tool.
After the frame is removed, your arm or leg will be weaker than it was before the injury, so you will need to do exercises to help build up your strength again. But with the help of the external fixation and your doctor, your bones can heal and you can get back to your normal activities.
