External Fixators: Understanding Uses & Benefits

An external fixator is a medical device used to stabilise broken bones or to correct certain deformities. It consists of metal pins or screws that are surgically inserted into the bone and then connected to a metal frame outside the body. The frame can be adjusted to apply the desired amount of pressure or traction to the bone.

External fixators are commonly used for:

Bone fractures that are too complex or severe to be treated with a cast or internal fixation devices

Broken bones that have failed to heal properly

Bone infections

Deformities such as clubfoot or bowlegs

External fixators are usually applied in a hospital operating room under general anaesthesia. The procedure typically takes one to two hours.

After the fixator is applied, you will likely stay in the hospital for a few days so that your doctor can monitor you for any complications. Once you are released from the hospital, you will need to follow your doctor's instructions regarding:

Care of the fixator

Pain management

Range of motion exercises

Weight-bearing restrictions

You will also need to follow up with your doctor regularly so that he or she can check on the progress of your healing.

External fixators can be a very effective way to treat complex bone fractures and deformities. However, they can also be associated with certain complications, such as:

Infection

Pin loosening

Skin irritation

Nerve damage

If you are considering an external fixator, it is important to discuss the risks and benefits with your doctor.
