[A modification of the Matti-Russe operation].

The essence of this modification is the curved structure of the cavity in the scaphoid bone and of the bone graft which fits into the cavity. The indication for the Matti-Russe method extends to those cases in which the direction of the line of pseudarthrosis is unfavourable and the proximal fragment is relatively small. The mechanical stability increases, because the wall of the cavity on all sides remains equally thick.
