Abstract
A palmar dislocation of scaphoid and lunate is uncommon. We have found only 19 reported cases in the literature. We reported a simultaneous, divergent dislocation. The closed reduction followed by percutaneous pinning has given a good result without avascular necrosis of any carpal bone.
Highlights
Fractures and dislocations of the carpal bones usually present as perilunar dislocation
A 40-year-old man injured his right hand when he fell on the outstretched hand while bicycling, radiograph of the wrist showed a palmar dislocation of both scaphoid and lunate (Figures 1 and 2)
Radiographs showed no evidence of avascular necrosis of the carpal bones, but a dorsal intercalated segment instability (DISI) deformity was observed
Summary
Fractures and dislocations of the carpal bones usually present as perilunar dislocation. A palmar dislocation of the scaphoid and lunate is a very exceptionnal injury. A few cases have been reported.[1] A 40-year-old man injured his right hand when he fell on the outstretched hand while bicycling, radiograph of the wrist showed a palmar dislocation of both scaphoid and lunate (Figures 1 and 2).
