Clinical Description of Fistula of Joint (M25.1)

Definition

A fistula of a joint is an abnormal connection or passageway that forms between the joint and the skin or another organ. This condition can arise due to various underlying causes, including infection, trauma, or inflammatory diseases. The presence of a fistula can lead to complications such as chronic pain, joint dysfunction, and increased risk of infection.

Etiology

Fistulas in joints can develop from several factors:
- Infections: Conditions such as septic arthritis can lead to the formation of a fistula as the body attempts to drain pus or infected material.
