Tightness at the end of the fracture may be related to nerve damage and abnormal sensation after the fracture. It may also be caused by extreme swelling of the tissues. Fractures are usually caused by violence, and the fracture may also cause nerve fiber strain around the fracture, resulting in abnormal function, and other sensations besides pain and numbness, such as tightness, ant walking and other sensory abnormalities. After the fracture, the broken end of the fracture and the surrounding soft tissues will bleed a lot and cause tissue swelling, extreme tissue swelling, there will be obvious tightness, and the swollen area will be as hard as a stone when pressed, which will lead to the serious complication of osteofascial compartment syndrome after the fracture. This is a serious complication that requires urgent surgical incision and decompression. If there is obvious tightness at the broken end of the fracture after the fracture, it is recommended that the patient go to the hospital in time to clarify the cause of the disease and then carry out regular treatment.
