Abstract
1. During two years eighty-five children with supracondylar fractures of the humerus were admitted to a children's hospital. This paper is a study of the severe fractures which occurred in twenty-three children of whom fifteen had a deformity at review.
2. The only deformity found after treatment by closed manipulation was an alteration in the carrying angle. It is considered that cubitus varus was caused by medial angulation of the distal fragment.
