We report two cases of capitellar fracture, one with malunion and the other with elbow dislocation. The first patient was a 69-year-old woman with malunion of a capitellar fracture causing pain and limiting the range of motion of the right elbow. She had fallen onto her left hand 7 months before her first visit. Osteotomy of the malunited fragment, anatomical restoration, and fixation of the fragment with DTJ screws were performed. At 13 months after surgery, her elbow pain was reduced, and flexion had improved from 120°to 130°, and her JOA score had recovered from 70 points to 91 points. The second patient was a 75-year-old woman who had fallen down steep stairs suffered a capitellar fracture with elbow dislocation and bilateral radius distal end fracture. The capitellar fragment was reduced and fixed with DTJ screws. At 10 months after surgery, she had slight pain, a range of elbow motion of -15°to 120°, and her JOA score had recovered to 76 points.
We consider that anatomical reduction and fixation of the capitellar fragment with a DTJ screw might be a good method for treating cases of capitellar fracture with malunion or dislocation.
