Navicular Bone of the Foot
2008 Nucleus Medical Art, Inc.
A navicular fracture can be caused by a fall, severe twist, or direct trauma to the navicular bone. It can also be caused by repeated stress to the foot, creating a fracture not due to any acute trauma (a stress fracture ).
A risk factor is something that increases your chance of getting a disease or condition.
The following factors may increase your risk of a navicular fracture:
Symptoms of a navicular fracture include:
- Vague, aching pain in the top, middle portion of your foot, which may radiate along your arch
- Increasing pain with activity
- Pain on one foot only
- Altered gait
- Pain that resolves with rest
- Swelling of the foot
- Tenderness to touch on the inside aspect of the foot
Your doctor will ask about your symptoms and medical history, and perform a physical exam, which will include a thorough examination of your foot. Other tests may include:
X-raya test that uses radiation to take a picture of structures inside the body, especially bones Bone scana test that creates an image of the bones by using a low-dose radioactive substance injected into a veinCT scana type of x-ray that uses a computer to make pictures of structures inside the body MRI scana test that uses magnetic waves to make pictures of structures inside the body. This is particularly useful with stress fractures. TreatmentTalk with your doctor about the best treatment plan for you. Treatment options include: Nonsurgical TreatmentMost cases of navicular fracture respond well to being placed in a cast that holds the bones in place. You will need to use crutches to help you walk. Once the bone has healed, your doctor will recommend a rehabilitation program that will allow you to eventually return to your normal activities. SurgeryIn rare cases of severe fracture, you may need surgery to realign the bone. This involves placing a metal plate and/or screws or pins to hold the bone in place. You will need to wear a cast or splint after the surgery. You will also need to use crutches to help you walk. Prevention To prevent navicular fractures and other fractures of the foot:
Wear well-fitting, supportive shoes appropriate for the type of activity you are doing.Eat a diet rich in calcium and vitamin D.Do weight-bearing exercises to build strong bones.Build strong muscles and practice balancing exercises to prevent falls.
