I have seen several of these cases recently which then again prompts me to get behind the camera and record a short educational video. Wrist tendinitis can be caused by multiple types of activities, but the increasing number of repetitive strain injuries associated with the use of smart phones, especially single hand phone handling that relies on thumb scrolling, seems to be an increasing percentage. The thumb extensor tendon loops underneath a dorsal wrist ligament called the retinaculum, and the friction of the tendon underneath the retinaculum creates pretty significant inflammation and scarring over time, leading to pinpoint pain on the inside of the wrist during activities that involve wrist extension, holding and picking up objects, and rapidly moving your hand towards the outside of your wrist. When it's becoming an entrenched problem, we have to treat it obviously, but the proverbial ounce of prevention goes a long way in this case. Making sure you scroll with the opposite hand of your phone holding hand will virtually eliminate a lot of left-sided wrist tendinitis, which means that occasionally you have to put on your cup of coffee to use your right index to scroll. Better yet, get off your smart phone and start doing something more beneficial for yourself.
