Name of journal: JBJS case connectorAbstract: CASE: We describe a patient with Bain grade-2b Kienbock disease with a coronal fracture of the distal lunate articular surface with proximal structure collapse. To reestablish midcarpal congruity, we used a bone-anchored suture to repair the coronal split in the lunate in preparation for lunate preservation with osteochondral medial femoral trochlea (MFT) reconstruction.CONCLUSION: In Bain grade-2b Kienbock disease, lunate reconstruction of both the proximal and distal joint surfaces can be performed. Successful reconstruction of the distal articular surface can be achieved using a bone-anchored FiberWire (Arthrex) suture technique. This can be employed in conjunction with an osteochondral MFT reconstruction of the proximal aspect of the lunate. Patients with this commonly encountered coronal fracture of the distal articular surface may be considered candidates for lunate reconstruction via this technique rather than conventional ablative procedures.All authors: Gillis JA, Higgins JPFiscal year: FY2018Digital Object Identifier: Date added to catalog: 2018-07-06
