What Are Fallen Arches?

Pain Management Health Center

What Are Fallen Arches?

If you look at an adult foot from the inside, you'll usually notice an upward curve in the middle. This is called an arch. Tendons -- tight bands that attach at the heel and foot bones -- form the arch. Several tendons in your foot and lower leg work together to form the arches in your foot.

When the tendons all pull the proper amount, then your foot forms a moderate, normal arch. When tendons do not pull together properly, there is little or no arch. This is called flat foot or fallen arch.

If osteoporosis has caused a spinal compression fracture, the treatment should address the pain, the fracture, and the underlying osteoporosis to prevent future fractures. All components of treatment have improved greatly in the last decade, says Michael Schaufele, MD, a physiatrist and professor of orthopaedics at Emory University School of Medicine in Atlanta. "We have better interventional options to treat fractures and better treatments to prevent future fractures," he tells WebMD. The majority...

Test Yourself for Flat Feet

You can easily test yourself to see if you might have fallen arches or flat feet. Follow these three steps:
Get your feet wet.
Stand on a flat surface where your footprint will show, such as on a concrete walkway.
Step away and look at the prints. If you see complete imprints of the bottom of your feet on the surface, then you're likely to have flat feet.

Many young children have flat feet, a condition referred to as flexible flat feet. When the child stands, the feet look flat. But when the child rises to his or her toes, a slight arch appears. In most cases, as children grow older, the arches develop.
Causes of Flat Feet and Fallen Arches

Flat feet in adults can arise from a variety of causes. Here are the most common:
An abnormality that is present from birth
Stretched or torn tendons
Damage or inflammation of the posterior tibial tendon (PTT), which connects from your lower leg, along your ankle, and to the middle of the arch
Broken or dislocated bones
Some health conditions, such as rheumatoid arthritis
Nerve problems

Other factors that can increase your risk include:
Symptoms of Flat Feet and Fallen Arches

Many people have flat feet -- and notice no problems and require no treatment. But others may experience the following symptoms:
Feet tire easily
Painful or achy feet, especially in the areas of the arches and heels
The inside bottom of your feet become swollen
Foot movement, such as standing on your toes, is difficult
Back and leg pain

If you notice any of these symptoms, it's time for a trip to the doctor.
Diagnosing Flat Feet and Fallen Arches

Your doctor examines your feet to determine two things:
Whether you have flat feet
The cause(s)

An exam may include these steps:
Checking your health history for evidence of illnesses or injuries that could be linked to flat feet or fallen arches
Looking at the soles of your shoes for unusual wear patterns
Observing the feet and legs as you stand and do simple movements, such as raising up on your toes
Testing the strength of muscles and tendons, including other tendons in the feet and legs, such as the Achilles tendon or the posterior tibial tendon
Taking X-rays or an MRI of your feet

Treatment for Flat Feet and Fallen Arches

Treatment for flat feet and fallen arches depends on the severity and cause of the problem. If flat feet cause no pain or other difficulties, then treatment is probably not needed. In other cases, your doctor may suggest one or more of these treatments:
Rest and ice to relieve pain and reduce swelling
Stretching exercises
Pain relief medications, such as nonsteroidal anti-inflammatories
Physical therapy
Orthotic devices, shoe modifications, braces, or casts
Injected medications to reduce inflammation, such as corticosteroids

If pain or foot damage is severe, your doctor may recommend surgery. Procedures may include the following:
Fusing foot or ankle bones together (arthrodesis)
Removing bones or bony growths -- also called spurs (excision)
Cutting or changing the shape of the bone (osteotomy)
Cleaning the tendons' protective coverings (synovectomy)
Adding tendon from other parts of your body to tendons in your foot to help balance the "pull" of the tendons and form an arch (tendon transfer)
Grafting bone to your foot to make the arch rise more naturally (lateral column lengthening)
Home Remedies for Flat Feet and Fallen Arches

There are home remedies to prevent or manage pain from fallen arches or flat feet. Here are some areas to consider:

Wear footwear or shoe inserts that are appropriate to your activity.
When pain occurs, try at-home treatment of rest, ice, and over-the-counter nonsteroidal anti-inflammatories, or NSAIDS, such as ibuprofen.
Ask your doctor or a physical therapist to show you stretches that can prepare you for feet-intensive activities.
Limit or treat risk factors that can make fallen arches or flat feet worse, such as diabetes, high blood pressure, and obesity.
Avoid activities that put excessive stress on your feet, such as running on roads.
Avoid high-impact sports such as basketball, hockey, soccer, and tennis.
Know when to get help. When pain is severe or interferes with activities, it's time to see the doctor for a thorough exam and treatment.
