Trans-scaphoid and trans-capitate perilunate fracture-dislocation of the wrist with concomitant ipsilateral fractures: a case report

AbsractAll perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. The most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. The reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. Concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsal injuries usually resultfrom a fall on the outstretched hand or motor vehicle accidents although othermechanisms are also mentioned. We describe here a case of dorsal trans-scaphoidtrans-capitate perilunate fracture-dislocation together with posterior olecranon fracture-dislocation of the left upper extremity. To the best of the authors' knowledge,such a case with this concomitant elbow fracture-dislocation has not been previouslyreported in the literature.
