Rib fractures are fine without a chest strap when the pain is tolerated. Chest belt fixation is only to reduce the degree of chest movement caused by breathing movement, reduce the range of movement of the fracture broken end, so as to reduce the pain caused by rib fracture, so if the pain of rib fracture can be tolerated without affecting the normal respiration, it is possible to do without the chest belt. However, if the pain of rib fracture is aggravated after removing the chest strap, and accompanied by chest tightness and breath holding, it is not recommended to remove the chest strap, especially for multiple rib fracture, which seriously affects the breathing, wearing the chest strap can help to improve the respiratory function, and reduce the movement of the broken end of the fracture, thus promoting the recovery. Therefore, the specifics should also be decided according to the fracture, as long as there is no chest tightness, breath-holding, and can tolerate the pain, the chest strap can also be removed.
