Abstract
Although studies on malrotation of the humerus possibly leading to dysfunction of the shoulder have been reported, studies on its causes are inadequate. The authors encountered a patient complaining of malrotation accompanied by dysfunction of the shoulder which occurred during treatment of a distal humeral fracture. The patient recovered the shoulder function by only correcting malrotation of the humerus without direct treatment on the shoulder, and we report it herein with a review of the literature.
Figures and Tables
Fig. 1
(A) Initial radiographs show a comminuted open fracture of the distal humerus. (B) Radiographs after the emergency operation show open reduction and internal fixation with a long anatomical plate on the anterior aspect of the medial column and a short reconstruction plate on the lateral column.

Radiograph 7 months after the initial operation shows non-union of the distal humeral fracture with loss of reduction.
