Periscaphoid Perilunate Dislocation of the Wrist

Combined Reverse Perilunate and Axial–Ulnar Dislocation of the Wrist: A Case Report

“…Because there was no complete scapho-lunate dissociation, the case cannot be categorised as a pure reverse perilunate dislocation but as a combined reverse perilunate and axial–ulnar pattern of wrist disruption. In fact, this case represents the mirror image of the combined perilunate–axial dislocation described several times in the literature under a variety of diagnoses (Andréet al, 1981; Connell and Dyson, 1955; Duparc and Huten, 1982; Healey et al, 2002; Higgs, 1930; Horton et al, 2004; Polveche et al, 1995; Russell, 1949; Sakada et al, 1998; Walker, 1943; Yammine et al, 2000).…”

“…Axial disruptions seldom involve dislocation of the lunocapitate joint. Only a few cases have been published where the capitate together with the scaphoid, trapezium, trapezoid and the corresponding metacarpals dislocated in block displacing proximally and radially (Andre´et al, 1981;Connell and Dyson, 1955;Duparc and Huten, 1982;Healey et al, 2002;Higgs, 1930;Horton et al, 2004;Polveche et al, 1995;Russell, 1949;Sakada et al, 1998;Walker, 1943;Yammine et al, 2000). Such an unusual axial-radial pattern of carpal instability always involved complete disruption of the hamate-capitate joint.…”
