Which is a modifiable risk factor for new onset lateral elbow tendonitis?

• A. Female Sex
• B. Repetitive elbow/wrist flex/ext > 2 hours/day
• C. Smoking History
• D. Dominant Arm

Answer: (B)

Overuse of the wrist extensor muscles, especially where they attach at the lateral epicondyle, leads to tiny tears and degeneration at the tendon origin—a hallmark of lateral elbow tendinopathy. Because the injury arises from repetitive loading, reducing or altering that activity is the most direct modifiable risk factor. Limiting elbow and wrist flexion/extension repeated work, taking breaks, adjusting technique or ergonomics, and addressing overuse can prevent onset and aid recovery. The other factors aren’t the same kind of targeted, changeable exposure. Sex isn’t something you can change, the dominant arm is not a proven modifiable risk exposure for onset, and while smoking can be altered, its link to new onset of this condition is less direct than the impact of repetitive overuse.
