Foot and ankle problems usually fall into the following categories:
- Acquired from improper footwear, physical stress, or small mechanical changes within the foot.
- Arthritic foot problems, which typically involve one or more joint.
- Congenital foot problems, which occur at birth, are generally inherited.
- Infectious foot problems, which are caused by bacterial, viral, or fungal disorders.
- Neoplastic disorders, usually called tumors, which are the result of abnormal growth of tissue and may be benign or malignant.
- Traumatic foot problems, which are associated with foot and ankle injuries.
"Fallen arches" is a common term used to describe a flatfoot condition that develops during adulthood. This should not be confused with other causes of flatfoot that may develop during childhood or adolescence.
Most cases of “fallen arches” develop when the main arch-supporting tendon (the posterior tibial tendon) becomes weakened or injured, causing the arch to gradually become lower. With time, the shape of the foot changes and secondary symptoms start to appear.
Common problems associated with fallen arches include plantar fasciitis, tendonitis, increased fatigue, and arthritis of the foot and ankle.
