Biological and molecular profile of fracture non‐union tissue: current insights

Delayed bone healing and non‐union occur in approximately 10% of long bone fractures. Despite intense investigations and progress in understanding the processes governing bone healing, the specific pathophysiological characteristics of the local microenvironment leading to non‐union remain obscure. The clinical findings and radiographic features remain the two important landmarks of diagnosing non‐unions and even when the diagnosis is...
