Dislocation of the scaphoid.

DISLOCATION of the scaphoid is a rare injury of which only a few reports of its occurrence appear in the literature. These include Higgs (1930), two cases; Buzby (1934); Kuth (1939); Wood-Walker (1943); Schlossbach (1954) and Connell & Dyson (1955), all reporting single cases. Russell (1949), in a review of intercarpal dislocations and fracture dislocations reported only one case of dislocation of the scaphoid. Thompson, Campbell & Arnold (1964) discussed nine cases of primary and secondary dislocations of the scaphoid, the majority being secondary dislocations. Two further cases are presented, and a possible mechanism for its production discussed.
