Causes

This problem is caused by:

• A direct blow
• A twisting injury

Risk Factors

Playing contact sports may raise the risk of this fracture.

Symptoms

Problems may be:

• Pain and tenderness that may be worse when moving the leg
• Problems walking or putting weight on the leg
• A change in how the lower leg looks

Diagnosis

You will be asked about your symptoms, health history, and how the injury happened. An exam will be done. It will focus on the lower leg.

Images will be taken of the leg. This can be done with x-rays.

Treatment

It may take 4 to 6 months to heal. The goals of treatment are to ease pain and swelling. Medicine can help. Other options are:

• A splint, brace, walking boot, or cast to keep the bone in line as it heals
• A walker or crutches to take weight off of the leg as it heals
• Exercises to help with strength, flexibility, and range of motion

Children's bones have growth plates that let bones grow and harden with age. A child with a fracture may need to be checked over time to make sure the bone heals the right way and keeps growing.

Prevention

To lower the risk of this type of fracture:

• Wear safety equipment when playing sports or doing activities.
• Always wear a seat belt when driving or riding in a motor vehicle.
• Do not do things that may cause a fall.
