An hypothesis of the pathogenesis of curb in horses.

This research article proposes a new theory regarding the development of the equine condition known as “curb,” considering factors such as the horse’s conformation (body shape and structure), the type of work it performs, and relevant mechanical factors. The proposed preventive measure is progressively increased workload until the horse’s plantar tarsal ligament is strong enough to resist regular forces.

Understanding Curb in Horses

• The condition in horses commonly known as “curb” is a swelling on the hind legs of the horse, specifically located on the plantar tarsal ligament.
• This ligament stretches across the back of the hock, a joint in the horse’s hind leg that corresponds to the ankle in humans.
• Horses who suffer from this condition experience pain and reduced mobility, which may hinder their performance and quality of life.

Proposed Theory of Curb Development

• The researchers suggest a new theory for how curb develops in horses, considering three major factors: the horse’s body structure (conformation), the kind of work the horse does, and relevant mechanical factors.
• The article assumes that horses with certain body structures may be more prone to develop curb, for instance, horses with straighter hind legs or a more upright hock angle.
• The type of work a horse does may also contribute to the development of the condition, especially regarding strenuous activities or those that involve extreme stretching or tension in the hock area.
• Mechanical factors may refer to the external forces that act on the horse’s body, such as workload, ground surface type, or heavy riding among others.

Prevention Strategy

• The researchers suggest a preventive approach against curb, which incorporates gradually increasing the horse’s workload.
• The goal of this strategy is to strengthen the horse’s plantar tarsal ligament over time, thus making it more resilient to withstand regular stress without breaking down and swelling.
• By gradually increasing the horse’s activity level in a controlled manner, the tendon has the opportunity to adapt and strengthen, potentially preventing curb development in the long run.
