[The most frequent tendon injury: the "mallet finger". Review, therapeutic concept and results].

This study covers treatment and after-treatment of 126 extensor tendon injuries of the DIP-joint in 125 patients over a period of 4 years. Tendon injuries were classified into 4 types and the final results were evaluated using a modified Riedeberger and Zeumer scale. In recent subcutaneous tendon injuries conservative therapy is indicated, depending on the primary extension deficit (less than 20 degrees modified Stack splint, greater than 20 degrees Mommsen plaster of Paris or special dressing). Chip fractures should be stabilized by pull-out suture.
