External Fixation For Leg Fractures In Children
What is external fixation?
- External (eks-TER-nal) fixation (fik-SA-shun) of a leg fracture is surgery to repair your child's broken leg. A leg fracture is a break in any of the bones of your child's leg. These bones may include the femur, tibia, fibula, and patella. The femur, or the thigh bone, is the longest bone in your child's body. The tibia, or shin bone, and the fibula, located behind the tibia, make up the lower leg. The leg bones help support your child's weight, and may break in different locations depending on the cause.
- Leg fractures may be simple (a single crack or break), or may break into many pieces. They usually happen because of a direct blow or if the leg is hit straight on. With external fixation, pins and devices sticking out of the leg will hold together broken pieces of bone inside the leg. While being held together, the pieces of broken bone will grow together and get stronger.
What are the signs and symptoms of a leg fracture?
Your child may feel severe pain in his leg. A lump, swelling, and bruise may also be seen at the site of the fracture. Your child may have trouble walking or putting weight on the affected leg. He may also have difficulty raising the affected leg while lying down. A bone may even stick out through the skin. He may also have a deep cut reaching down to the bone and have a lot of bleeding.
When does my child need an external fixation?
Your child may need external fixation for a leg fracture after trauma. Trauma includes bad injuries caused by a fall, car accident, sports injury, or physical abuse. His bone may break into several pieces, and may be hard to put back together without surgery. He may have his bone sticking out through the skin, or a deep cut reaching down to the bone. His leg fracture may be near important parts of his leg bones like the epiphyses (growth plates). This part of the leg bone is where new bone grows, making your child grow taller. Fractures may affect the epiphyses and affect your child's growth.
What tests are needed before an external fixation?
Your child's caregiver will get a complete medical history and do a physical examination. He may also ask about how your child broke his leg. Your child may need one or more of the following tests:
- X-rays: Your child may need x-rays of his leg to check for broken bones or other problems. Several pictures may be taken of the bones in your child's leg. An x-ray of his uninjured leg may also be taken.
- Computerized tomography scan: This test is also called a CT or CAT scan. This is a type of x-ray that uses computers to take pictures of your child's leg. Your child may be given a dye before the pictures are taken to help caregivers see the pictures better. People who are allergic to iodine or shellfish (lobster, crab, or shrimp) may be allergic to some dyes. Tell your child's caregiver if your child is allergic to shellfish or has other allergies or medical conditions.
- Magnetic resonance imaging scan: This test is also called an MRI. The test uses magnetic waves to take pictures of the leg and ankle.
