Review Question - QID 7892

A 47-year-old man who is right-hand dominant reports lateral-sided elbow pain after playing golf. His symptoms developed gradually and without trauma, and he has pain with gripping and repetitive movements with the hand and wrist. Examination reveals his shoulder and wrist to be normal, and the elbow has no effusion and normal range of movement. He is tender near the lateral epicondyle, and symptoms are exacerbated with resisted wrist extension. Radiographs are shown in Figures 104a and 104b. What is the next most appropriate step in management?
