Cryotherapy of the distal limbs: an effective treatment for equine laminitis following onset of lameness?

Summary
# Cryotherapy for Acute Equine Laminitis: Current Evidence and Clinical Considerations Cold therapy applied to the distal limbs in the acute phase of laminitis has long been considered a cornerstone management strategy, yet robust clinical evidence supporting its effectiveness remains limited. Ryde's 2021 systematic review examined four studies (three randomised controlled trials and one retrospective cohort study) to determine whether cryotherapy initiated after clinical signs of laminitis appear improves outcomes compared to untreated controls. The evidence base, whilst showing promise, is classified as weak: experimental studies demonstrated reduced histological lamellar damage and inflammatory changes in treated limbs, whilst the single clinical cohort study reported decreased severity of laminitis in horses receiving cryotherapy. However, translating these histopathological improvements into documented better functional outcomes—such as reduced pain scores, faster return to work, or prevention of chronic changes—remains inadequately demonstrated. For practitioners, this suggests that whilst early cold therapy appears mechanistically sound and unlikely to cause harm when applied appropriately, it should not be considered a standalone solution; rather, it should be integrated within a comprehensive acute laminitis management protocol including farrier intervention, analgesia, and stable management, with recognition that individual case factors and available resources must guide clinical decision-making.

Practical Takeaways
- •Cryotherapy may reduce tissue damage in acute laminitis when applied early after clinical signs appear, but current evidence is weak and inconclusive
- •Consider cryotherapy as a complementary treatment option, but do not rely on it as a standalone intervention without other evidence-based laminitis management strategies
- •Additional quality research is needed before making strong recommendations; individual case assessment and owner communication remain essential
Key Findings
- •Cryotherapy of distal limbs reduced histological changes and lamellar injury in randomised controlled trials
- •Clinical severity of laminitis was reduced in horses treated with cryotherapy in retrospective cohort study
- •Overall strength of evidence is weak due to limited number and quality of studies available
- •Further randomised controlled trials are needed to establish definitive clinical efficacy
