Summary The objective of this retrospective study was to provide a detailed description of the characteristics of condylar fractures represented in a population of 135 horses who sustained 145 fractures. Records and radiographic studies were examined. Fifty‐nine percent of the horses were male and the majority Thoroughbreds. The distribution of fractures was 37% incomplete‐nondisplaced, 30% complete‐nondisplaced and 32% complete‐displaced. The right front was more likely to sustain a complete‐displaced fracture, whereas the left front was more likely to sustain an incomplete‐nondisplaced fracture. Forelimbs (81%) and lateral condyles (85%) were more likely to be involved. Contrary to previous studies, the right forelimb was slightly more often involved than the left Fractures tended to involve the middle portion of the condyle (59%). The mean length of all fractures was 75 ± 3.8 mm. Axial fractures and medial condyle fractures tended to be longer. Fifteen percent of the fractures had definitive articular comminution. Ninety‐five percent of fractures with articular comminution were associated with complete fractures. When fractures entered the middle area of the condyle, 23% had articular comminution. Eight of the fractures spiralled, all involved forelimbs. Concurrent lesions included proximal phalanx chip fractures, sesamoid fractures, sesamoiditis, proximal phalanx fractures, ‘splint’ bone periostitis and ligamentous injuries. The complete description of the fractures in this group of horses allows us better to define the condylar fracture, compare these fractures to previous studies and establish new data for use in defining prognosis.
