External fixation is a surgical method used to stabilize broken bones or support healing after surgery. It involves placing a frame outside the body, which is connected to the bone with pins or screws. This technique allows for adjustments to be made without additional surgery and is often used in complex fractures or when the skin is damaged. The external fixator can be adjusted to maintain proper alignment of the bone during the healing process. It is particularly useful in cases where traditional casts are not effective, such as in open fractures or when there is significant swelling.
