Condylar fracture of the cannon bone with axial sesamoid fracture in three horses.

This research article presents case histories of three young thoroughbred racehorses that experienced a particular type of bone fracture known as a displaced lateral condylar fracture, which was further complicated by an axial fracture of the lateral sesamoid bone. The research suggests that recognising sesamoid bone fractures is crucial for providing a more accurate prognosis when treating condylar fractures in racing thoroughbreds.

Introduction

• The research presents the cases of three young thoroughbred racehorses that have experienced a specific kind of bone fracture. This type of fracture, known as a displaced lateral condylar fracture, arises in the cannon bone – a limb bone in horses. However, these cases were further complicated by an axial fracture of the lateral sesamoid bone, which is a smaller bone located at the back of the limb joint.

Case Histories and Treatment

• In two of the cases, veterinary surgeons performed a surgical repair of the condylar fracture. Despite the surgical intervention, both horses developed severe degenerative joint disease and remained lame, indicating the outcome was not favorable.

Importance of Recognising Axial Fractures

• The study emphasizes the importance of recognizing the presence of axial fractures of the sesamoid bone during diagnosis. An axial fracture corresponds to a break along the axis of the bone, implying a potentially more severe and complicated condition.
• The researchers argue that recognizing these types of fractures in the initial diagnosis is crucial for providing a more accurate prognosis for the treatment of condylar fractures. Particularly in the case of thoroughbred racing horses, this can inform decisions about future participation in races, treatment options, and the potential need for humane euthanasia, as happened with the third horse in the study.
