I was palpating a guy's biceps tendon today in clinic when he grabbed my hand, twisted it behind my back, and put me in a headlock.
Patient: Oh, sorry, Doc. I should have warned you about that.
I guess that counts as a positive test. Also, never do a physical exam on a military guy without backup.
(It actually kind of hurt my wrist, but that wrist has been hurting for around a week now. I reduced a hip last Friday and I must have been positioned wrong because i felt a pop in my wrist and it's been sort of sore ever since. I was worried I tore something (TFCC came to mind) but I have full motion and almost full strength, so I don't think I did. But it's been clicking nonstop since then and having it forcefully twisted behind my back really didn't help the situation)
