Dislocation of the Carpal Scaphoid

Isolated Dislocation of the Carpal Scaphoid

“…This is the position, with slight variation, which is seen in the X-rays of the majority of the cases. This mechanism, suggested by Connell & Dyson (1955), is confirmed by a study of these cases. As a point of interest all reported cases have been men.…”

“…It receives but scant attention in many standard textbooks and none a t all in others. Nigst & Buck-Gramcko (1975) Connell & Dyson (1955). By contrast the other and entirely unrelated type of displacement of the scaphoid, that known as rotational subluxation ( o r dislocation), has been abundantly documented during the same period.…”

A Case Report of an Isolated Dislocation of the Scaphoid in a Lesser Arc Injury and a Review of the Literature

“…Substantial force is required to disrupt the scaphoid from its fossa which more commonly fractures the radial styloid or the scaphoid waist [6]. As a result, isolated scaphoid dislocations without secondary fractures, such as that in the presented case, are especially uncommon.…”

Dislocation of the scaphoid

“…Connell & Dyson (1955), in reporting a dislocation of the scaphoid, observed that in most cases, including their own (a man riding a cycle that collided with another), the injury occurred when the hand was gripping something in ulnar deviation. In other cases, a street-car driver holding a knob control (Kuth, 1939); a motor cyclist (Russell, 1949); two further motor cyclists (Higgs, 1930); accident while driving a car (Buzby, 1934), all sustained a forced ulnar deviation of the wrist.…”
