Summary
Chronic laminitis with distal phalangeal rotation remains challenging to manage, particularly when therapeutic shoeing exacerbates lameness in horses with compromised hoof quality; this case series explored whether long-term confinement on sand bedding could improve hoof architecture in two bilateral laminitic stallions over 20 weeks. Both horses were transitioned to barefoot housing in confined sand bedding after failing to improve with farriery interventions, with hoof measurements and radiographic angles assessed at regular intervals. Sole depth began increasing at the 8-week mark and continued throughout the study period, whilst heel depth remained static; notably, hoof angles decreased significantly by week 20, with changes in the sole/heel depth ratio strongly correlating to reductions in phalangeal rotation. The findings suggest that extended sand bedding confinement may offer a viable management strategy for laminitic horses unresponsive to traditional trimming and shoeing, though the mechanism—likely involving biomechanical offloading and consistent support—requires investigation in larger populations. Given these promising outcomes, equine professionals managing chronic laminitis cases with poor shoeing prognoses might consider sand bedding confinement as an adjunctive or alternative approach, whilst recognising that individual response times and hoof quality variability will influence clinical decision-making.

Practical Takeaways
- •Consider long-term confined sand bedding (minimum 20 weeks) as an alternative management strategy for chronically laminitic horses that fail to improve with conventional trimming and shoeing
- •Monitor sole depth progression from 8 weeks onward as a clinical indicator of hoof remodeling; heel depth changes may lag behind sole depth changes
- •Sand bedding confinement may reduce pain and allow natural hoof remodeling in cases where therapeutic shoeing has aggravated lameness, particularly in horses with poor hoof quality
Key Findings
- •Sole depth increased significantly starting at 8 weeks of sand bedding confinement, while heel depth remained unchanged throughout the 20-week period
- •Hoof angles decreased by 20 weeks of housing, with increase in sole depth/heel depth ratios strongly correlated to reduction in hoof angles
- •Two stallions with bilateral chronic laminitis and severe lameness post-shoeing showed improved hoof conformation and apparent correction of phalangeal rotation after 20 weeks of barefoot sand bedding confinement
- •Long-term sand bedding confinement may provide an alternative management approach for laminitic horses that respond poorly to therapeutic shoeing
