Diagnostic Code 5213 · 38 CFR §4.71a
Supination and pronation are the rotational movements of your forearm. Supination turns your palm upward, like holding a bowl of soup. Pronation turns your palm downward, like typing on a keyboard. These movements depend on the radius bone rotating around the ulna. When this rotation is impaired by fracture residuals, arthritis, or bone deformity, many daily tasks become difficult, including using tools, turning keys, eating with utensils, and typing. Veterans commonly lose forearm rotation from forearm fractures, elbow injuries, or wrist trauma sustained during service.
