The general principles of arthrocentesis, you don't have to memorize any angles or any of that. All you have to do is remember four principles. One, you always want to use the extensor surface of the joint. Why? Because on the flexor surface is where the tendons, the vessels, and the nerves run-- flexor of the elbow, flexor of the knee. So you want to stay away from those.
Number two-- you want to try to flex the joint about 20 or 30 degrees. On all of the joints that you're doing it on, you try to flex them about 20 to 30 degrees. Third, you distract. You try to distract. And fourth, you always use-- excuse me-- a needle detached from the syringe. The big mistake people make is they don't use a needle detached from the syringe, and then you can't field yourself going into the joint.
Imagine doing a spinal tap with the syringe attached. It would be much tougher. So on this one, we're doing the lunate, the wrist joint arthrocentesis, so we find the lunate. And then you distract. You bend to 30 degrees of flexion. You go right here between the radius and the lunate. And there you are. You're right in the joint.
You obviously don't go in that far. You're going about this far. But that just shows you how easy it is to get into that joint.
