title: [Trans-triquetral triquetral-lunate arthrodesis].
abstract: Transtriquetral triquetro-lunate arthrodesis is an original technique for partial arthrodesis of the wrist. This operation is indicated in the treatment of certain forms of triquetro-lunate instability and represents a new approach to the treatment of Decoulx's stages I and II of Kienböck's disease. The incision is medial and limited. The use of a special trephine guided by a pine allows the extraction of a triquetro-lunate osteocartilaginous cylinder. A cancellous bone graft is then performed to fill in the loss of substance. This new, simple surgical procedure, but demanding in terms of its technique, should decrease the failure rate and should improve the chances of lunate revascularisation.
