Primary and Secondary Dislocation of the Scaphoid Bone

Abstract

1. Nine cases of disturbance of the relationship between the scaphoid and the radius and between the scaphoid and the lunate bones are described. 2. Persistent dislocation of the scaphoid bone may follow reduction of perilunar dislocations or of other dislocations of the proximal row of the carpus. It may be obvious, as in waist-deep dislocation, or may be solely a rotational dislocation which may be difficult to diagnose. 3. Uncorrected rotational dislocation of the scaphoid bone caused significant disability in six of seven cases. 4. Aids to the diagnosis of this condition are described and a vigorous approach to the problem of correction is advocated. 5. The experience of other workers in this field is reviewed and discussed.

Isolated scaphoid dislocation: A case report and review of literature

“…Twelve of the 15 cases were immobilized by casts without any internal fixation, and most had fully recovered wrist functions after follow-up (durations of 3 mo to 10 years). The exception to this involved two cases classified as secondary dislocation, where the patients suffered from severe stiffness and mild pain of the wrist, as reported by Thompson et al [ 38 ]. The other three were immobilized using K-wires to reduce the scapholunate diastasis under arthroscopic assistance and achieved good outcomes as well[ 17 , 21 , 22 ].…”

“…The classification of isolated scaphoid dislocation was as described by Leung et al [ 2 ]. Only four cases (4/48) were categorized as secondary dislocation, and were all reported by Thompson et al [ 38 ]. Among the 44 primary dislocations, 29 were simple (24 partial, 5 total) and 15 were complex (13 partial, 2 total).…”

“…Possible complications of isolated scaphoid dislocation might be degenerative joint and carpal instability, which are likely to be seen in neglected cases[ 6 , 7 ]. However, in this literature review, 4 of the 48 cases showed scapholunate diastasis during the follow-up after open reduction, although in none of them was diagnosis delayed[ 16 , 21 , 33 , 38 ]. A degenerative joint developed in 5 cases (5/48), and of those, diagnosis was delayed in 3, with delay time ranging from 2.5 mo to 9 mo before the patients underwent salvage procedures[ 13 , 26 , 38 ].…”

Isolated Dorsal Fracture–Dislocation of the Scaphoid: A Case Report

“…Most of them are volar dislocations of the scaphoid, isolated or in combination with perilunate dislocation or carpal dislocation. An isolated dorsal dislocation of the scaphoid is rare: the literature contains only six recorded cases (Kuth, 1939; Russell, 1949; Thompson et al, 1964). We also found two reports of dorsally dislocated fracture–dislocation of the scaphoid, in which a chip fracture of ulnar aspect of the scaphoid was noted (Inoue and Maeda, 1990; Parks and Stovell, 1973).…”

Total Scapholunate Dislocation With Complete Scaphoid Extrusion: Case Report

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] We have found only 17 reported cases in the literature that involve simultaneous dislocation of the scaphoid and lunate. 5,6,8,9,[12][13][14] In 11 of these cases, the 2 carpal bones dislocate as a unit.…”
