===Complications===

Some fractures may lead to serious complications including a condition known as [[compartment syndrome]]. If not treated, eventually, compartment syndrome may require [[amputation]] of the affected limb. Other complications may include non-union, where the fractured bone fails to heal, or malunion, where the fractured bone heals in a deformed manner. One form of malunion is the malrotation of a bone, which is especially common after femoral and tibial fractures.<ref>{{cite web |url= https://www.lecturio.com/concepts/compartment-syndrome/ |title= Compartment Syndrome |website= The Lecturio Medical Concept Library |access-date= 2021-06-25 |archive-date= 25 June 2021 |archive-url= https://web.archive.org/web/20210625130431/https://www.lecturio.com/concepts/compartment-syndrome/ |url-status= live }}</ref>
Complications of fractures may be classified into three broad groups, depending upon their time of occurrence. These are as follows –
# ''Immediate'' complications – occurs at the time of the fracture.
# ''Early'' complications – occurring in the initial few days after the fracture.
# ''Late'' complications – occurring a long time after the fracture.
