Never before has a technology been so universally accepted as the modern era cell phone, otherwise known as the smart phone. They are everywhere. Anywhere one looks, a person staring at their smart phone will be encountered. Walk down a busy city street and try to find someone that makes eye contact; you are more likely to literally run into somebody walking toward you so engrossed in their smart phone world that their walking is slow, automatic, and inattentive. This applies to people of all ages. The social implication of this epidemic is altogether another topic, but of concern to the modern era physician is the potential musculoskeletal consequence of this behavior.
