RESUMEN
All perilunate fracture-dislocations combine bone avulsions, ligament disruption and fractures in different forms. The most frequent pattern is the dorsal transscaphoid perilunate fracture-dislocation. The reported risk of missed initial diagnosis in perilunate dislocations is as high as 20%. Concerning pathomechanics of the perilunate fracture-dislocation, it should be noted that most dorsal injuries usually result from a fall on the outstretched hand or motor vehicle accidents although other mechanisms are also mentioned. We describe here a case of dorsal trans-scaphoid trans-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 previously reported in the literature
