Do not fill this in!== What as medics should we do if we come across this? == I think the most important thing we can do is to make sure something more serious isn't going on (and then offer reassurance if that's the case). There are two major nerves other than the radial that go to the hand. Rarely, they too can be damaged by tight cuffs. This could potentially be disabling because these other nerves control muscles in the hand and damage could result in severe motor dysfunction (such as weakness or muscle wasting). So it's very important for us to test for any muscle weakness in the hand, thumb or fingers. If the person says it feels weak or you detect weakness, the person may need special splints and/or physical rehab and so should get it checked out further. Another serious sign to look out for is total numbness, total anesthesia in a certain area. When the nerve insulation is just damaged or the nerve is just bruised, the sensation may be off, weird, tingly, burning, different, decreased, "numb-ish," but not totally numb. If there no feeling at all in any particular area to light touch, then that indicates a nerve has probably been cut totally through and the sensation in that area may actually never recover. We also want to make sure the symptoms are not arising from nerve damage higher up in the spine or arm. If someone gets in a car accident, for example and is handcuffed and then ends up complaining of thumb or forefinger numbness, one might just attribute it to the handcuffs and tell the person that it's basically harmless and it will go away on it's own. Meanwhile, what may be happening is that the symptoms may actually be arising from a spinal injury sustained in the crash. So the thing to do is see if there is any sensory loss on the pad side of the thumb, or in the upper 2/3 of the forearm. Either of these would indicate that the nerve damage is probably located in the neck, not the wrist, so make sure to examine these areas with a light touch to see if it extends onto the "front" side of the thumb or up the forearm. Wrist fractures caused by violent handcuffing or transpost can cause similar symptoms, so if there is any bony tenderness one should consider getting the person's wrists imaged.
