Clinical signs

The clinical picture includes swelling, ecchymosis, and pain with range of motion. In some fractures, a deformity may be present.

Pearl: These injuries are commonly associated with a painful subungual hematoma. Painful collections may be decompressed with an 18-gauge needle through the nail. Non-painful collections do not require evacuations. If decompression is needed, it is advisable to perform the procedure within 24 hours of the injury.
