1. An attempt has been made to demonstrate the fact that most fractures and dislocations of the carpus follow a sequential pattern. The primary loss of relationship occurs at the junction of the fixed axis of the hand with the forearm (the capitate-lunate joint) resulting in a perilunar dislocation of the wrist.
2.Manifestations of the basic perilunar dislocation will vary individual cases depending upon the direction and power of the deforming force, the anatomical differences in the various carpal bones, the ligamentous structures, and the state of the muscles while the injury is occurring.
3. The result of treatment in the individual case can be predicted by recognizing the presence and the extent of associated fractures, particularly of the navicular, and by the accuracy of reduction when closed methods are used.
