Use of a dynamic compression plate and a cable cerclage system for repair of a fracture of the radius in a horse.

The research documents the successful use of a dynamic compression plate and cable cerclage system to repair a fracture in the radius of a horse. The treatment resulted in modest residual lameness and no complications during foaling.

The Patient

• A 9-year-old pregnant Peruvian Paso mare was brought in for examination due to a fracture in the left radius.
• The horse was observed to have grade IV/V (severe) lameness in the affected forelimb.
• Radiography revealed an oblique displaced fracture extending from the mid-diaphysis (middle) of the radius to the humeroradial joint (the joint between the radius and humerus).

Treatment Plan

• The veterinary team recommended repair with internal fixation to minimize the risk of degenerative joint disease in the humeroradial joint.
• This treatment involved the application of a dynamic compression plate to the cranial aspect (front surface) of the radius.
• Additionally, three 2mm stainless steel cable cerclages were positioned around the mid- and proximal (near to the body) diaphysis.
• After surgery, the horse was kept in a sling for 8 to 12 hours each day over a period of 3 weeks.

Outcome

• Five months post-surgery, the mare gave birth without complications.
• In terms of mobility, a grade I/V (mild) lameness was reported during trotting only.
• This suggests that the combination of a dynamic compression plate and cable cerclage may be an effective solution for stabilizing such fractures in small to medium-sized horses, although there may be some residual lameness.
