Fracture complexity must be considered when formulating treatment options and prognosis. In adult horses, reconstruction of a complex fracture should not be attempted unless there is at least 180° of the cortex available to support axial weight bearing and load sharing with any implants [180]. Cortical discontinuity or comminution results in a gap at the fracture site such that there is no fracture compression with applied axial loads. A fracture gap promotes cyclic bending or torsion of the implant with the fulcrum at the level of the fracture and results in eventual failure of the implants [180]. Many complex long bone fractures that are not considered repairable in the adult horse are repairable in the foal because of lower body weight and propensity for rapid healing [172,181–184] (Chapter 37).
