Activity in the distal condyles of the third metacarpal and metatarsal bones requires careful assessment to discriminate a stress‐related response from a potential fracture [98]. It has been suggested that scintigraphy of horses that are lame or performing poorly is not an effective screening technique for prodromal condylar fractures [106]. It would be more accurate to say that nuclear scintigraphy does not predict the likelihood of sustaining a condylar fracture. It is known that bone fatigue associated with condylar fractures may develop rapidly, arise in sound horses and result in a fracture before an osteoblastic response is initiated [98]. This is indeed the risk carried by any horse in training undertaking fast work when prodromal features may not be apparent. However, in the presence of lameness a bone response is likely to have been initiated, and scintigraphy is unlikely to produce a false negative result whether or not the clinical features are related to an impending condylar fracture.
