Under Nail Hematome

 06 April 2022   

Nail injury

Under nail hematomas are common nail bed injuries caused by blunt or sharp trauma to the fingers or toes. Bleeding from the rich vascular nail bed results in increased pressure under the nail and can cause significant discomfort. Under nail drainage, also known as nail bed trephination, can be performed to relieve this discomfort.

Under nail hematome drainage is indicated in the presence of a painful subungual hematoma with the nail edges intact

The nail may fall off during the week following hematoma drainage but should regrow as long as the germinal matrix is intact
