Summary
The third metacarpal bone (McIII) is a common site of long bone fractures in racehorses. However, articular fractures of the dorsomedial aspect of McIII are a rare location of such injuries. This report describes the successful standing surgical repair of an articular fracture of the dorso‐medial proximal McIII in a 4‐year‐old Standardbred racing mare using lag screw fixation.
