Palmar dislocation of scaphoid and lunate as a unit

A case of closed palmar dislocation of the scaphoid and lunate as a unit is described. This was treated by closed reduction and resulted in a good functional result as assessed at 1-year follow-up. No aseptic necrosis of the lunate or of the scaphoid developed. The only residual abnormality was an asymptomatic x-ray VISI pattern of the lunate. This is attributed to the disruption of the lunotriquetral joint. A functional analysis of the x-ray films with the wrist in radial and ulnar deviation indicated a normal arthrokinematic pattern.
