Why is thermal necrosis of bone problematic?

Explanation:
Thermal necrosis weakens bone at the osteotomy by killing bone cells and damaging the local blood supply, which creates a larger area of nonviable, resorbing tissue around the cut ends. That expanded zone of resorption undermines structural stability and delays healing, heightening the risk of delayed union or nonunion. Enhanced osteogenesis would require viable osteoblasts and good vascularity, which heat damage disrupts, so that’s unlikely. Thermal injury also tends to increase pain and inflammation rather than reduce it, and it does not promote faster healing.
