Provider Prepared's Weekly Pearl of Wound Wisdom #32 Smashing!

A 50 year old male presents to the Emergency Department after smashing his left thumb with a sledge hammer. He has increasing pressure like pain associated with increasing subungual hematoma.

Pain associated with a subungual hematoma is caused by pressure building in a contained space between the nail bed and the nail plate.

Trephination is indicated for the relief of pressure and thus pain of a  subungual hematoma; when the injury is less than 24-48 hours old, is not draining spontaneously, and has intact nail folds. Trephination can be accomplished with electrocautery devices or with the boring technique using a needle. Use of a heated paperclip is discouraged, many paperclips are now made of materials that are not capable of retaining sufficient heat for trephination.                                           Fastle, RE et al. Subungual hematoma. UpToDate  December 2016.
