Normal value and range of the humerus-elbow-wrist angle in a sample of healthy children with even distributions of age, sex, and laterality.

This study was performed to evaluate the normal value of the humerus-elbow-wrist angle (HEWA) in a sample of healthy children with even distributions of age, sex, and laterality. A total of 168 radiographs of the elbows of healthy children with even distributions of age, sex, and laterality were reviewed. The mean HEWA was 12.1° (range: 5°-20°). The value of HEWA was significantly associated with increasing age. Neither sex nor side showed significant differences for the HEWA. The data should be useful for postoperative radiographic assessment of cubitus varus or valgus deformities.
