✓ Correct answer: B. 50%; Transhumeral amputationAnswer: 50%; Transhumeral amputation The patient is receiving rehabilitation due to a partial arm amputation after an industrial accident. 50% of the humerus has been preserved, indicating that the surgery performed was a transhumeral amputation. A transhumeral amputation preserves a significant portion of the humerus, typically between 30-70% of its length. An amputation that preserves less than 30% of the humerus length is typically referred to as a short transhumeral amputation.
