[Osseous or ligamentous injuries of the phalango-interphalangeal joint and their treatment].

To understand the types of injuries occurring in PIP joints, the anatomical and biomechanical aspects are described. Bony abruptions of the palmar plate of the PIP joint are important indicators of the severity of accompanying capsular and ligamentous injuries and assist in determining specific forms of treatment. A classification of the different injury types is presented. The indication for conservative or operative treatment is based on this classification.
