The Use of Confined Housing in Sand Bedding and Trimming to Manage Phalangeal Rotation and Hoof Malconformation Over a 20-Week Period in Two Laminitic Stallions.

This research examines the use of confined housing in sand bedding and routine trimming as a novel and alternative method to manage and improve hoof conditions in two stallions suffering from chronic laminitis, a severe foot ailment in horses that causes pain and leads to malformation of hooves.

Understanding Chronic Laminitis

• Chronic laminitis is a severe stage of a disease known as laminitis in horses. It features a painful condition called distal phalangeal rotation and general foot pain.
• Several interventions including different trimming and shoeing methods have been tried to address this issue. However, these techniques sometimes exacerbate the lameness, more so in horses with inherently poor hoof quality.

Sand Bedding as an Alternative Solution

• Given the limitations in existing solutions, a new alternative has been explored – using sand bedding confinement. This technique appeared to relieve foot pain in horses afflicted with laminitis.
• This research aimed to understand the impact of long-term sand bed confinement on the hoof conditions and to establish the duration required for this method to produce notable improvement.

Methodology of the Study

• Two stallions with severe lameness and bilateral chronic laminitis were selected for this investigation. They were housed in confined sand bedding accommodations with no shoes.
• The sole depth began to show improvement after 8 weeks, while the heel depth remained constant throughout the period.
• At 20 weeks of confinement, a decrease in hoof angles was observed. Higher sole-to-heel depth ratios were closely linked to the reduction in hoof angles.

Conclusion and Future Research

• After 20 weeks, long-term housing in sand bedding confinement managed to correct phalangeal rotation and enhance hoof conformation in both stallions suffering from chronic laminitis.
• While this was a positive development, the study calls for further validation with larger sample groups. This will help understand if using sand bedding as a strategic treatment approach can be applied more broadly to laminitic horses who do not respond well to usual shoeing management.
