According to the Rosenthal classification, what is Zone II?

• A. Proximal to distal end of lunula
• B. Distal to lunula
• C. Distal to bony phalanx
• D. At the proximal phalanx

Answer: (B)

Zone II in the Rosenthal classification refers to the area that is distal to the lunula. The lunula is the crescent-shaped, whitish area at the base of the nail that can be seen through the nail plate, and it is important to recognize its position when discussing nail and distal phalanx injuries or conditions. In this classification, Zone I is generally recognized as being proximal to the lunula, while Zone II starts just after the lunula and extends toward the tip of the nail, encompassing the area most commonly affected by nail pathology, including nail bed injuries and disorders. Understanding the precise zonal classifications assists clinicians in diagnosing and treating nail and phalangeal conditions effectively, particularly in cases of trauma, infection, or other nail disorders. Identifying these zones provides a framework for clinicians to communicate findings more clearly, ensuring that they can accurately describe the location of any issues or interventions required.
