In the presence of nail pterygium, what should be avoided?

In the case of nail pterygium, the primary concern is to prevent further damage to the nail matrix and surrounding tissue. Pushing back the nail with instruments can exacerbate the condition by causing additional trauma or irritation to the area affected by pterygium. This can lead to more inflammation or potential infection, worsening the situation.

Maintaining the integrity of the nail bed and surrounding soft tissues is crucial in managing nail pterygium effectively. Other actions, such as cutting the eponychium or trimming the nail, may need to be approached with caution, as they can also affect the health of the nail area, but they do not carry the same immediate risk as using instruments to push back the nail. Applying nail polish does not directly impact the condition of the nail pterygium, making it a safer choice in this context.
