Coronal Fracture of the Lunate in Advanced Kienböck Disease: Reestablishing Midcarpal Congruency to Enable Osteochondral Reconstruction: A Case Report.

In Bain grade-2b Kienböck 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.
