When vertical compression forces, created by axial load, are applied to the finger, comminuted, intraarticular, compression fractures may result. These fractures are very unstable. Typically, they occur in two configurations:
as centrally impacted, comminuted fractures, or with a T- or Y-type fracture geometry. It is desirable to obtain stable fixation to allow early motion and to minimize the risk of degenerative joint disease.
