Lateral Knee X-ray

Here's one of my more common imaging errors in the world of x-ray. The lateral knee requires a lot of attention in the area of tube angle because of body habitus. When the patient has wide hips, more tube angle is required to get the knee perfectly lateral. In this image, I had the central ray positioned properly but not quite enough tube angle to get the joint space completely opened. The medial epicondyle should be almost perfectly superimposed over the lateral epicondyle. In my example here, it is not...

Patella Fracture

The doorbell rings... You drop what you are doing and start running to answer it.  As you cross your living room at a trot, you catch your knee on the corner of a coffee table...  The result of that impact is shown above.  I didn't bother and ask who was at the door, because if it was an insurance salesman, I'd probably have laughed.  I guess this knee would have been a pre-existing condition at that point, huh? 

Oh well... today was rather uneventful with this little exception...
