What is the term used when gout specifically affects the MTP joint of the big toe?

The term used when gout specifically affects the metatarsophalangeal (MTP) joint of the big toe is podagra. This condition is characterized by sudden and severe pain, swelling, and redness in the affected joint, which is often the first indication of gout. Podagra is significant because it highlights the classic presentation of gout, where urate crystals accumulate in the joint, causing inflammation and discomfort.

Understanding podagra is essential for recognizing gout's clinical manifestations and differentiating it from other types of arthritis or joint problems. The terminology used in this context helps medical professionals communicate effectively about various forms of arthritis, particularly those associated with crystal deposition diseases like gout.
