Palmar Scaphoid Dislocation Associated With Dorsal Perilunate Dislocation: Case Report

Rare Perilunate Injury as a Result of Chronic Trauma in 3-Year-Old Girl

“…Few complications have been described, although in some cases, they could be related to an insufficient reduction. 8 As well as the resultant bone instability, volar lunate dislocation may also cause pressure and resultant dysfunction to the median nerve as it enters the carpal tunnel, therefore, emergency reduction of the perilunate dislocation is needed to reduce the pressure on the median nerve to try and prevent progression of nerve damage. There are also reports of the ulnar nerve being affected as a result of volar dislocation of the lunate.…”

“… 6 The perilunate luxation can rarely be treated using closed reduction. 2 3 4 5 6 7 8 But in a retrospective study, primary ligamentous repair and internal fixation with K-wires managed to maintain the anatomy of the scapholunate joint and produce better results than closed methods. 7 8 The procedure in this case was performed by means of open reposition using dorsal approach and the wrist was stabilized by two K-wires.…”

Congenital Ulnar Carpal Bone Luxation in a Miniature Donkey Treated by Pancarpal Arthrodesis

“…16 Similarly, traumatic luxation of the ulnar carpal bone is unlikely in our case because these are typically associated with some degree of soft tissue swelling and joint effusion when they occur in small animals and humans. [17][18][19] Finally, no case of individual carpal bone luxation or dislocation could be found in the equine literature without associated complex carpal fracture. 20 In this unusual case of severe unstable carpal valgus due to luxation of the ulnar carpal bone, pancarpal arthrodesis using two small LCPs proved efficient in fusing the carpal joints and offering a good postoperative comfort.…”

Offene, palmare Luxation des Os scaphoideum bei posttraumatischer Radiusfehlstellung: Ein Fallbericht

“…In der Literatur wurden weitere Fälle einer isolierten, palmaren Skaphoidluxation nach fehlverheilter Radiusextensionsfraktur berichtet [7,8]. Es ist also davon auszugehen, dass auch in unserem Fall die vorbestehende Fehlstellung das Eintreten der Luxation begünstigte.…”

“…Es besteht Einigkeit darüber, dass für ein möglichst gutes Ergebnis eine frühe definitive Versorgung anzustreben ist [8,11]. Offene Vorgehensweisen werden zunehmend favorisiert [5,7].…”
