M84.2: Delayed union of fracture

Delayed union of fracture refers to a condition where a bone fracture takes longer than usual to heal. In most cases, a fractured bone begins to heal within certain expected timeframes based on the type and location of the fracture, as well as individual health factors, among other things. However, with delayed union, the healing process extends significantly beyond this expected timeframe. The symptoms may include persisting pain at the fracture site and instability of the affected area well beyond the normal healing period. It is important to note that delayed union is different from nonunion, where the fracture fails to heal completely. A variety of factors can contribute to delayed union, including severe bone breakage, inadequate blood supply, infection, and certain lifestyle habits like smoking or excessive alcohol consumption.
