[Snapping palmar drawer phenomenon of the wrist: a physiologic or pathologic study finding?].
In the examination of a wrist, when this is held in neutral position and moderate ulnar deviation, a substantial palmar drawer translation combined with a snap can be elicited. The sign is most evident in about 15 degrees of ulnar deviation, while it is negative in the neutral position, in radial deviation or in maximal ulnar deviation. The translation and the snap have been consistently demonstrated in normal wrists and are therefore considered physiologic. The knowledge of this impressive phenomenon seems important for differential diagnosis when assessing the stability of a wrist; its clinical and cineradiographic picture are described.
