T‐locking compression plate fixation of a cranial mid‐body axis fracture in an adult horse

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 showjumping or steeplechase 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 8‐year‐old Warmblood gelding that sustained the injury during a showjumping course. Following reduction, a five‐hole 4.5‐/5.0‐mm locking compression T‐plate (4.5/5.0 T‐LCP) was contoured to fit the ventral aspect of the axis and used as an internal fixator. The horse was turned out starting 2 months after surgery, and training was gradually resumed. No lameness, ataxia or decrease in cervical range of motion were reported after surgery. Follow‐up radiographs performed 5 months postoperatively confirmed bone union at the fracture site resulting from adequate reduction and stabilisation. T‐LCP fixation is a promising treatment option for cranial mid‐body fractures of the axis.
