Try to bend your injured finger to check for dislocation or malrotation of your knuckle.  If your knuckle is dislocated, you may not be able to bend it at all as the bone will have moved in a way that does not allow you to use your finger.  If the bone has rotated, you might be able to bend the finger, but it will be pointed towards your thumb.  Malrotation means that the bone has twisted in such a way that the finger will bend in a different direction than normal.  If your bone is dislocated or malrotated, you will need a doctor to reset it. A malrotated or dislocated knuckle often takes longer to heal than a simple broken knuckle. If your knuckle is broken it will be very difficult for you to close your hand.  You can test the severity of your injury by trying to make a fist.  Your hand may have swollen too large or it may simply be too painful for you to move your fingers if your knuckle is broken.  You may also be able to close all your fingers except for the one with the broken knuckle.  If you can make a fist, and your knuckle is broken, your injured finger may not align properly with the rest of your fingers. Don’t push yourself.  If you try too hard to fight through the pain and make a fist, you could injure or dislocate your knuckle further. A broken knuckle will drastically reduce your finger strength.  Your brain can shut down the muscles around a severe injury to prevent further damage.  If you find yourself unable to get a tight grip on anything, there’s a chance your brain is trying to protect your broken knuckle. If you have a minor fracture of your knuckle, you may still be able to use most of your grip.  If you suspect you might have a fracture though, take it easy.  Gripping something too hard could cause the fracture to become more severe. Your knuckle is at the top of your metacarpal bone.  The bottom of your metacarpal bone is connected to your carpus or wrist bone.  Because the two bones are connected, a broken knuckle can affect the mobility of your wrist.  Move your wrist from side to...
