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