title: [Static and dynamic anatomo-radiology of the wrist].
abstract: Carpal instability is a difficult problem and a static as well as a dynamic radioanatomical study of the wrist is indispensable for correct diagnosis. This study is based on the description of the variations of the aspects of the bones of the proximal carpal row. An analysis of the projection of each individual bone was made, and thus, the author was able to describe the radioanatomical features of the wrist in three positions: neutral, radial and ulnar deviation. Secondly, the author points out the modifications produced on a normal wrist by active and passive loading. On the posteroanterior views, the most important stresses seem to be rotational (pronosupination) and translational. On the lateral views, the anterior and posterior "drawer" movements are particularly interesting. The author emphasizes the features of normal, lax and pathological wrist patterns.
