Existing or Worsening Symptoms of Kienböck's Disease after Distal Radius Fracture: Two Case Reports.

We report two rare cases of existing or worsening symptoms due to Kienböck's disease after distal radius fracture (DRF). During examination, radiographs show changes in the lunate bone; there was persistent wrist pain after treatment for DRF. In each case, surgeries were performed: A combined therapy (bone marrow transfusion, bone peg graft, external fixation, and low intensity pulsed ultrasound) for one, as well as carpal coalition for another. The etiology of these case presentations suggest that a compression fracture of the lunate due to a DRF resulted in softening and sclerosis.
