The Modified Wagner Foot Ulcer Classification system categorizes ulcers based on their depth and the extent of infection or other complications. A full thickness ulcer extending to the tendon or joint without signs of abscess or osteomyelitis is classified as Grade 2.

This classification highlights that the ulcer is indeed deeper, involving structural elements such as tendons or joints, but does not present with the more serious complications seen in higher grades. Grade 2 specifically indicates significant tissue loss, but still preserves the absence of infection, which is critical in determining the management approach for the ulcer. Grades beyond this, such as 3 or 4, would involve either bone infection or presence of abscess, distinguishing them from the characteristics of a Grade 2 ulcer.
