Three cases of non-displaced radial fracture in horses.

The research article discusses the diagnosis and treatment of three horses with non-displaced radial fractures – a type of bone fracture where the bone cracks but does not shift or move out of place.

Case Observations

• The researchers documented three cases of non-displaced fractures of the radius in horses. The fractures were characterized by sudden, severe forelimb lameness and swelling in the antebrachium, the area between the elbow and the carpus (or ‘knee’ in horses).
• In two of the cases, there were associated wounds on the medial (the side toward the center of an animal’s body) aspect of the distal (the part of a limb or similar appendage furthest from the center of the body) radius.

Diagnosis

• The diagnoses of these fractures were confirmed through radiographic examination. Radiography, or X-ray imaging, is a technique often used in veterinary medicine to view the internal structures of an animal’s body. In this case, it allowed the researchers to detect the fractures in the horses’ radii (the plural of radius).

Treatment and Healing

• All three horses were treated conservatively through box rest. Box rest is a common treatment for bone fractures in horses where the horse is kept in its stall with limited movement to allow the bone to heal naturally.
• Notably, in one case, a slight further displacement of the fracture occurred three weeks after the initial injury. It means that the fracture moved slightly from its original position, which can complicate the healing process.
• Despite this, all three fractures went on to heal over time, demonstrating that box rest can generally be an effective treatment for non-displaced radial fractures in horses.

Post-treatment Outcomes

• Upon healing, all three horses were able to return to some level of work or exercise. However, two of the horses could only handle light ridden exercise, implying that while the overall healing of the fractures was successful, complete recovery of pre-injury activity levels was not achievable in all cases.
