Desmitis of the fetlock annular ligament in the horse.

This study focuses on the diagnosis and treatment of desmitis in the fetlock annular ligament of horses. Thirty horses were diagnosed with this condition over an eight-year period, and most experienced chronic lameness. Longitudinal ligament cuts were performed on 25 of the horses, with 16 returning to full work without any issues. The study suggests that untreated horses do not recover from this condition.

Context and Purpose of Study

• The study explores desmitis, an inflammation of the ligaments, specifically focusing on the fetlock annular ligament in horses. This ligament is crucial for a horse’s movement and any inflammation can cause severe lameness and affect their performance.
• The purpose of the study is to provide insights into the diagnosis and treatment of this condition, and to determine the effectiveness of certain surgical procedures.

Diagnosis and Patient History

• Over eight years, thirty horses were diagnosed with desmitis of the fetlock annular ligament.
• Most of the diagnosed horses suffered from chronic lameness and exhibited symptoms of distended digital flexor tendon sheaths, a condition resulting from inflammation.
• Air tendograms, a type of imaging technique, revealed thickening in the palmar or plantar annular ligaments in these horses.

Treatment Procedure and Results

• The researchers used a surgical procedure wherein the ligament was cut longitudinally in 25 of the diagnosed horses.
• Out of these 25 horses, 16 returned to their full work capacity without any difficulty after recovery.
• One horse required a second operation to make a full recovery and return to soundness.
• Scientists kept track of these horses for a follow-up period of three months to seven-and-a-half years to monitor their long-term recovery.

Untreated Horses

• The study also observed the condition of five untreated horses diagnosed with desmitis of the fetlock annular ligament.
• Notably, none of these untreated horses recovered or returned to their work, emphasizing the importance of treatments in managing and healing this condition.
