Is a bone fracture serious? First, it needs to be clarified that a bone fracture is indeed very serious. This indicates that the external force involved at the time was quite strong, disrupting the continuity and integrity of the local bone. It usually manifests as local swelling, pain, and restricted movement. Some patients may experience extensive subcutaneous bruising, and even a low fever, so a bone fracture is indeed very serious. For such patients, active treatment with plaster cast immobilization is necessary, elevating the affected limb, and using non-steroidal anti-inflammatory and pain-relieving medications, as well as drugs that promote fracture healing.
