Figure 1 Preoperative evaluation. A: Clinical pictures showing the cubitus varus and hypertension deformity of the left elbow; B: Preoperative radiographs in antero-posterior and lateral views showing a humerus-elbow-wrist angle of 15º varus and a shaft condylar angles of 35º on the left side, and those of 13º valgus and 45º, respectively; C: Three-dimensional computed tomography analysis with overlapping of the mirror image model from the right humerus (green color) and the deformed model from the left humerus (blue color). Anterior view showing a 15º-degree varus deformity. Lateral view showing a 10º-degree hyperextension deformity. Axial view showing no rotational deformity.
