The size, physiology and behavioural characteristics of horses are such that long bone fractures commonly fall into this category. Despite improvements in implant design and surgical techniques, many repairs are to some degree incompletely reduced (often due to missing or avascular fragments) and/or slightly unstable. In these scenarios, secondary healing, or at best some gap healing, is likely. It is then a race between the stable fixation (the combination of reduced/stable areas and the implants engaging them) providing enough mechanical stability to brace the unstable areas until they are supported by secondary healing. The balance between these two processes dictates outcome. If there is evidence of gross instability, revisionary surgery or external support should be considered to restore some stability to the microenvironment of the fracture.
