Subungual hematoma
Subungual Hematoma
Subungual Hematoma (pronounced: suh-buhn-gwuhl hee-muh-toh-muh) is a medical condition that involves the collection of blood (hematoma) underneath a nail (subungual). The term is derived from the Latin words 'sub' meaning 'under', 'unguis' meaning 'nail', and 'hematoma' from the Greek words 'haima' meaning 'blood', and 'toma' meaning 'swelling'.
Causes
A Subungual Hematoma is typically caused by a severe injury to a finger or toe. Common causes include slamming a finger in a door, dropping a heavy object on the finger or toe, or repetitive impacts from activities such as running or playing certain sports.
Symptoms
The primary symptom of a Subungual Hematoma is a painful throbbing sensation caused by pressure from blood accumulation. The affected nail often turns purple-black due to the underlying blood. In some cases, the nail can become loose or even detach from the nail bed.
Treatment
Treatment for a Subungual Hematoma often involves relieving the pressure by draining the blood. This is usually done by a medical professional who uses a heated needle or a specialized drill (a process known as trephination). In severe cases, the entire nail may need to be removed to allow for proper healing.
