Volar Intercalated Segment Instability After Scapholunate Ligament Reconstruction

$25.00

ABSTRACT: We describe an 18-year-old man with an acute lunate dislocation treated with  open reduction, ligament repair, capsulodesis, and percutaneous pinning. After pin removal  and mobilization, the patient was found to have midcarpal collapse; the lateral radiographs  showed a volar intercalary segment instability. We now, besides open reduction internal  fixation scapholunate repair, recommend routine pinning of the lunotriquetral interval and  careful evaluation of the dorsal radiocarpal ligament during repair of lunate and perilunate dislocations.
