There is a correlation between suspensory ligament injuries in horses, arena footing depth, and low heel conformation, with horses having low heel conformation at higher risk, especially on deep arena footing. To mitigate this risk, it is essential to maintain arena footing at a consistent depth with proper moisture content and base support. For horses with low heels, corrective trimming and shoeing by a qualified farrier is crucial, potentially including wedge pads or egg bar shoes to enhance heel support. Regular conditioning programs should be implemented to gradually strengthen the suspensory apparatus, incorporating proper warm-up and cool-down periods.
The provided evidence, although not directly addressing the correlation between arena footing depth and low heel conformation, highlights the importance of managing suspensory ligament injuries through various means, including therapeutic ultrasound 1, surgical management 2, and understanding the risk factors for noncatastrophic suspensory apparatus injury 3 and the effects of injury to the suspensory apparatus, exercise, and horseshoe characteristics on the risk of lateral condylar fracture and suspensory apparatus failure 4.
Key considerations include:
- Maintaining optimal arena footing depth to reduce strain on the suspensory ligament
- Implementing corrective trimming and shoeing for horses with low heel conformation
- Gradually strengthening the suspensory apparatus through regular conditioning programs
- Monitoring for early signs of suspensory issues and intervening early with rest, controlled exercise, and possibly regenerative therapies to prevent progression to more serious injury.
Deep footing increases the strain on the suspensory ligament as the fetlock sinks deeper, hyperextending the joint, a mechanical stress that is amplified in horses with low heels due to the increased tension on the suspensory apparatus. Thus, managing arena footing and addressing low heel conformation are critical in preventing suspensory ligament injuries.
