A new classification for fingertip injuries.

A new classification of fingertip injuries is presented. The PNB classification separates the injury into its effect on the three components of the fingertip: pulp, nail and bone. This provides a three digit number that accurately describes the injury. This new classification can be used to record and document injuries, without having to resort to lengthy description. It could also be used to provide detailed instructions for treatment and indications for referral. Examples of the application of the classification are given.
