Leeds-Genoa Non-Union Index: a clinical tool for asessing the need for early intervention after long bone fracture fixation.

The non-union index derived from counting risk factors predicts union for 0-4 risk factors and non-union for 5-8 risk factors. It can be readily applied and can guide clinicians about the risk of development of long-bone non-union. It can become a powerful aid for assessing fracture fixation outcome and to support early intervention.
