Lesions and diseases of the distal radioulnar joint. Part II. Treatment

The treatment of fresh lesions of the distal radioulnar joint (DLLJ) has undergone significant changes in the last decade. While conservative methods used to be preferred, with the advent of new technologies such as computed and magnetic resonance imaging and arthroscopy, the treatment approach has become more radical. Fractures of the radius penetrating the DLLS, i.e., fractures of the sigmoid notch, require the same treatment as fractures of the carpal articular surface, where a 2 mm displacement is considered unacceptable because it leads to the development of deforming arthrosis within 5 years in 100% of cases. Complete removal of the displacement avoids osteoarthritis in 85% of cases.
