What is adult acquired flatfoot?

Fact Checked

There are various foot problems that can lead to the development of adult acquired flatfoot deformity which is a condition that occurs due to a collapsed arch where the foot is directed outward. Many individuals regardless of the cause of flatfoot can be treated with braces and orthotics. Those who could not be relieved with braces and orthotics might be remedied with surgery to help with the pain and deformity.

A common indication of flatfoot is the “too many toes” sign. It simply means that even the big toe can be seen from the back of the foot of the individual. In a normal foot, only the fourth and fifth toes must be visible.

Symptoms

Depending on the exact cause of flatfoot, the individual can suffer one or more of the following symptoms:

  • Bony bumps on the top and interior of the foot among those who have previous injuries or arthritis affecting the middle of the foot. In some cases, the bony spurs can be large that they pinch the nerves which results to tingling or numbness on the top part of the foot and into the toes.
  • Once the foot collapses, the heel bone can shift position and add pressure on the exterior of the ankle bone.
  • Those who are diabetic will notice swelling or a large-sized bump on the base of the foot. This large bump can cause skin issues and an ulcer can develop if proper diabetic footwear is not used.

What are the possible causes?

  • Posterior tibial tendon dysfunction involves damage to the posterior tibial tendon. This is considered as the most common cause of adult acquired flatfoot deformity. This tendon is responsible for holding up the arch and support the foot while walking. If this tendon is torn or inflamed, the arch will steadily collapse.
  • Rheumatoid arthritis can result to a sore flatfoot. This type of arthritis attacks not just the cartilage in the joints, but also the ligaments that support the foot.
  • Individuals who have diabetes or nerve issues with the foot can develop arch collapse.
  • Injuries to the ligaments in the foot can cause the joints to fall out of proper alignment. The ligaments support the bones and prevent them from moving. If they are torn, the foot will become sore and flat.

It is important to note that adult acquired flatfoot deformity is one of the prevalent problems that affect the ankle and foot. The treatment can range from non-surgical measures such as braces and orthotics or even surgery. The doctor will come up with the ideal treatment plan based on the exact cause of the deformity.
