Kienböck Disease in a 66-Year-Old Man after Distal Ulna Fracture

Kienböck disease after fracture-dislocations around the wrist is a rare occurrence. This case report presents a case of a 66-year-old man who developed Kienböck disease 18 months after his distal ulnar fracture. The patient developed negative ulnar variance after union of the distal ulnar fracture. Nonsurgical treatment was not effective in relieving his pain. Radial shortening osteotomy was performed based on the negative ulnar variance that developed. One year postoperatively, visual analog scale improved to 0, grip strength improved to 25 kg, and flexion-extension arc improved to 150 degrees. The patient achieved satisfactory clinical outcomes. This is a therapeutic level IV study.
