Glossary

The section is intended to help define some of the words used in the patient educational material in this section.  I have tried to use both medical terms and the common terms together in the materials.  My experience is that patients want to learn the most about their particular problem and discuss it using appropriate terminology.  Our job at Pittsburgh Foot and Hand Center is to thoroughly educator patient's about their particular foot or ankle problem as well as the treatment options. Highly educated patients often achieve the best results.
