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.
Gangrene occurs when there is a lack of blood supply to tissue, depriving it of oxygen, and thereby causing death and decay of the tissue. The two types of gangrene are wet (caused by bacterial infection) and dry (no infection). Most common causes of gangrene are diabetes, arteriosclerosis, tobacco abuse, burns, and frostbite.
Treatment for gangrene includes surgical removal of the dead tissue and use of antibiotics when infection is present.
