Ankle fracture

Correct answer: B

Explanation: Clavicle fractures account for approximately 2.6% of all fractures and for 44% to 66% of fractures about the shoulder. Middle third fractures account for 80% of all clavicle fractures, whereas fractures of the distal third account for 15% and those of the medial third for 5%. The most common cause of clavicle fractures is a direct blow to the shoulder, usually from a fall or a collision.

Explanation: Elbow fractures represent 8% to 9% of all upper extremity fractures in children. Of all elbow fractures, 85% occur at the distal humerus; 55% to 75% of these are supracondylar. Most occur in children between 5 and 10 years of age.
