Malunion - Definition

Definition


After a fracture, the bone is immobilized to allow the formation of a bone callus, allowing the formation of an identical bone in shape and just as strong as the original bone. But sometimes, especially when the fractured bone is immobilized in an unsuitable position, the bone healing occurs in the wrong position: this is a malunion. Usually the malunion does not interfere much with the individual, one can feel at times a little ball next to the fracture site. Sometimes, however, the malunion affects movement or comfort, and surgery to shave the callus can be performed.
