Les luxations périlunaires du carpe

Carpal perilunate dislocations are rare and underdiagnosed because of an ignorance of the pathology and an inappropriate incidence of radiography. The carpus is composed of two rows of bones and 33 ligaments. These ligaments are fundamental for wrist stability. Typically, the injury occurs in young male adults exposed to high-energy trauma with a wrist in hyperextension. The diagnosis is easy with a physical examen and standard postero-anterior and lateral radiographs. The Witvoët and Allieu classification of the perilunate dislocations is the most used. This classification is composed of three grades. The treatment is usually surgical and has to be realised in a short delay to minimize the important complications.SCOPUS: ar.j
