Pedal bone fractures are relatively common. The cause of them is variable, but we most commonly see them due to trauma (such as kicking a wall), or in horses with flat feet and thin soles which are galloped on hard ground.
Clinical signs of a pedal bone fracture:
‘Foot Soreness’ or ‘Acute Lameness’
Hoof tester response may be positive or negative.
Inflammation of the foot noted with increased digital pulses
Diagnosis:
Radiographic examination: The observation of a fracture line confirms the diagnosis.
Playdoh is used to help to remove superimposition of normal lines on the foot.
Sometimes if the two fracture pieces have not separated, then a repeat radiographic examination is needed 2 weeks later to be able to see the fracture line. The fracture is more evident as this stage due to remodelling of the fracture ends during the healing process.
Treatment:
If there is no involvement of the joint surface, a bar shoe with or without a foot cast is used.
Surgery is not needed.
Generally pedal bone fractures heal very well with a remedial shoe.
Fun fact: Pedal Bone fractures can heal but leave a permanent radiographically evident line for generations
Why?
They can heal by a fibrous union!
Our patients are very lucky that we are able to take radiographs in the field to give us a ‘horse side’ diagnosis to provide the best possible care for our patients.
