Luxation isolée du scaphoïde carpien. À propos d’un cas avec revue de la littérature

Isolated Dislocation of the Scaphoid with Associating Radial Styloid Fracture: A Case Report

“…A review of the literature found only 29 reported cases. Missed cases for two to four weeks reported in the literature but no reported cases neglected for six weeks [2] [3]. A characteristic radiograph feature that distinguishes dislocation of the scaphoid from perilunate dislocation is the palmar and radial displacement of the proximal pole of the scaphoid out of the scaphoid fossa of the radius.…”

“…Such dislocation is extremely rare. Because of this, treatment strategies can be conflicting and vague current treatment strategies now advocate ligament reconstruction as a first-line treatment to restore normal anatomy and preserve function [2]. The aim of this report is to present a case of isolated dislocation of the scaphoid with radial styloid fracture and present this unusual injury along with its treatment and to attempt to merge the available experience in the literature in a suggested algorithm that will guide the surgeon confronted with this rare problem to treat it promptly and effectively.…”

Neglected isolated scaphoid dislocation

“…The exact mechanism of scaphoid dislocation has yet to be established, but it is generally believed to involved dorsiflexion and ulnar deviation with or without rotational forces 12. There are several treatment options for scaphoid dislocation: Closed reduction and immobilization with a cast,34 closed reduction and percutaneous pinning,56 open reduction and pinning7 and open reduction and pinning followed by ligament repair 189. These treatment modalities are comparable in terms of long term clinical outcomes and share a relatively favorable prognosis.…”
