This illustration shows how even slight unicondylar depression may lead to angulation of the finger.

Anatomical reduction recommended

Although the DIP joint is very forgiving, articular fractures should be reduced anatomically. Otherwise, the articular cartilage may be damaged, leading to painful degenerative joint disease and digital deformity. At the DIP joint, this can well be dealt with by arthrodesis, which is a procedure with very predictable outcome, without any major perturbances of the finger.
