Your video has been so helpful! For the lateral, if the radius is too far forward, am I right thinking to externally rotate the wrist?

Yes, exactly. For a true lateral wrist, the ends of the radius and ulna should be superimposed, if the radius is a bit to far forward, externally rotate a bit.

We have added the Inverse Square and Direct Square laws, with some good shortcuts! Check those out, and let us know if there is a specific view or subject you would like a video on.

The PA-view should be done with the arm in 90° abduction. Putting the elbow and shoulder at the same height makes radius and ulna parallel (lowering the arm makes radius cross the ulna and thus relative shortening of radius). This can give a variation in ulnair variance, which can lead to misinterpretation of wrist instability.... Same for the lateral, you shoud more focus on the pisiform and scarpoid for positioning, a true lateral is not where the ulna and radius project over each other, but when the volair cortex of the pisiform is seen between the interval of the volair cortex of the scapoid and the volair cortex of the capitate. certainly important for maesuring the correct volair angle of the radius, VISI, DISI or subluxation of DRUJ. Also have the elbow flexed in 90° for a true lateral. Last but not least for the scapoid view; ulnair daviation but do it with a clenched fist, so let the patiënt really tension their wrist. 1. It puts pressure on the scapho-lunair joint, when subluxation of the SL-joint it will open more through the tension. 2. The fist makes the wrist flat and that way you really get that BANANA view of the scaphoid

Hello there, clearly you are in the medical field! A few points though...Through our positioning guides, primarily Merrill's and Bontrager's, probably the most commonly used positioning guides, describe and demonstrate the lateral wrist positioning as the Ulna and Radius superimposed (and yes, the shoulder, elbow and wrist should all be in the same plane), neither describe the specific superimposition of the pisiform and the scaphoid. For the scaphoid view, the standard scaphoid is what is demonstrated, but the Stetcher view, which is a specialty view (we were just demonstrating the standard views on this video) which is positioned with the hand flat on the palmar surface, with the IR angle 20° with a perpendicular beam, or the IR flat with a 20° CR, a variation of the Stetcher view is to clench the fist. That maneuver elevates the distal end of the scaphoid so it is positioned more perpendicular to the IR and widens the the fracture line, this maneuver may be very uncomfortable for the patient.

In February of last year (2022), I fell on the ice and landed on my left wrist (thankfully, it was my left, since I'm right-handed). The day after it happened, my wrist started hurting, so my husband went out and bought a wrist brace for me. The day after that, my dad was able to get his van out to take me to the ER. They saw how swollen my wrist was and put ice on it. They also did X-rays, and the doctor somehow managed to miss something, because they diagnosed me with a sprained wrist and told me to wear a wrist brace for a couple of weeks. After wearing the wrist brace for a month, I saw my own doctor, and they did more X-rays and found my wrist was broken, so I was referred to an orthopedic specialist. The ortho doctor had me wear a different wrist brace for three weeks, and when I went for the follow-up, they did X-rays, and my wrist had healed just the right way. Since then, I have lost the wrist braces, and wish I had them when my wrist starts hurting, which only happens when it's going to rain.

Hello, I am Glenn, one of the guys in the videos. Sometimes those factures can be missed, sometimes the swelling can push the bone together, making the fracture very hard to see.
