A bone fissure is actually a type of fracture. It refers to the occurrence of a fissure fracture in the cortex of the bone, but the stability of the bone remains intact. A bone fissure can also present symptoms such as localized pain, swelling, and restricted movement.

Following a bone fissure, there will be localized bleeding, and the surrounding soft tissues may also be damaged, contributing to swelling. Therefore, in the early stages of a bone fissure, it is advisable to immobilize and rest the affected area. Cold compresses can be applied to reduce local blood flow, thereby easing bleeding and alleviating swelling.
