Numbness after a fracture is not a normal manifestation. If numbness occurs in the area of the fracture that is swollen after the fracture, it usually represents extreme swelling of the local soft tissues, which compresses the local dermal nerves and results in numbness of the skin sensation. However, if the fracture leads to skin numbness in all the limbs distal to the fracture, two points must be considered: First, it is possible that the fracture has caused local swelling and compression of important local blood vessels, thus leading to numbness due to loss of blood supply to the distal end of the limb, loss of large arterial pulsation by touching the distal end, and the limb is colder. Second, the nerve of the limb is damaged after the fracture, resulting in numbness at the distal end of the fracture, which usually does not affect the blood circulation, the blood supply to the distal end of the limb is normal, and it is possible that the sensation disappears completely, and there is no pain or position sensation at all.
