Fingertip Fractures
Symptoms and Signs of Fingertip Fractures
The fingertip is swollen and tender. A fracture with significant soft-tissue injury may cause hyperesthesia, which frequently persists long after the fracture heals. Usually, blood becomes trapped between the nail plate and nail bed (subungual hematoma), causing a bluish black discoloration under all or part of the nail, which may be elevated. Subungual hematoma commonly occurs when the nail bed is lacerated. Marked disruption of the nail bed can result in a permanently deformed nail.
