Summary
Cranial mid-body fractures of the axis in horses result from
hyperflexion of the neck and are most commonly associated with lateral
bending falls over show jumping or steeple chase fences. In the authors’
experience, conservative treatment of mild to moderately displaced
cranial mid-body axis fractures has been unsuccessful. This case report
describes surgical management of a cranial mid-body fracture of the axis
in an eight-year-old warmblood gelding that sustained the injury during
a show jumping course. Following reduction, a five hole 4.5mm equine
compression T-plate was contoured to fit the ventral aspect of the axis
and used as an internal fixator. The horse was turned out starting two
months after surgery and training was gradually resumed. No lameness,
ataxia or decrease in cervical range motion were reported after surgery.
Check-up radiographs at five months post-op showed complete healing of
the fracture. T-Locking Compression Plate (T-LCP) fixation is a
promising treatment option for cranial mid-body fractures of the axis
with a good prognosis for athletic function.
