Equine laminitis: real veterinary case reports
Laminitis is inflammation and structural failure of the laminae — the velcro-like tissue holding the coffin bone to the hoof wall. When the laminae weaken, the bone rotates or sinks within the hoof capsule, causing severe pain and lameness. Most cases today are endocrine-driven, secondary to Equine Metabolic Syndrome (insulin dysregulation in overweight ponies and easy-keeper breeds) or Pituitary Pars Intermedia Dysfunction (PPID, also called equine Cushing's, in horses over 15).
Classic signs are a sawhorse stance with hind legs camped under the body and front legs stretched forward, reluctance to walk, shifting weight, and bounding digital pulses. Treatment is multimodal: immediate confinement on a deep soft surface, NSAIDs, cryotherapy in acute cases, supportive hoof care from a remedial farrier, and addressing the underlying endocrine cause with pergolide for PPID or strict dietary management for EMS. Prevention through good metabolic management is dramatically more effective than treating established disease.
What vets typically check for
- Resting insulin and oral sugar test — screens for insulin dysregulation (EMS).
- ACTH testing — diagnoses PPID, with seasonal reference ranges.
- Lateral foot radiographs — measure rotation and sinking of the coffin bone.
- Acute care: stall rest on deep soft bedding, ice boots for first 48-72 hours, NSAIDs.
- Long-term: remedial farriery, weight loss, low-NSC diet, pergolide if PPID confirmed.

- Effects of pasture consumption and obesity on insulin dysregulation and adiponectin concentrations in UK native-breed ponies.
Equine veterinary journal · 2026 · United Kingdom
A group of seven native-breed ponies in the UK were studied to see how eating grass and being overweight affected their insulin levels and a protein called adiponectin, which is important for preventing laminitis (a painful hoof condition). Over 22 weeks, the ponies gained weight and showed signs of insulin dysregulation, with insulin levels rising significantly after eating su
- Equine veterinarians' care priorities regarding vaccination, colic, lameness and pre-purchase scenarios.
Equine veterinary journal · 2026 · Netherlands
A study looked at what equine (horse) veterinarians think is most important when caring for horses and satisfying their clients. They found that in situations like colic (a painful digestive issue) and lameness (problems with movement), the quality of care was the top priority. When it came to buying a horse, professionalism was more important than in other situations. Overall,
- Effectiveness of acupuncture for equine laminitis: Systematic review and meta-analysis.
Journal Article · 2025
Recent research looked into whether acupuncture can help horses suffering from laminitis, a painful condition affecting their hooves. After reviewing several studies, the findings suggest that acupuncture can improve the lameness scores of affected horses, meaning they may move better and feel less pain. Specifically, when acupuncture was given twice a week for four weeks, it s
- Case report: The gastrointestinal nematode Strongylus vulgaris as a cause of hoof abscess in a donkey.
BMC veterinary research · 2025
A 19-year-old male donkey was brought in for severe lameness in his right front leg. After trying hoof wraps without success, the vet performed imaging and discovered a large abscess under the hoof, which contained a parasitic worm. The vet removed the worm and treated the abscess with drainage, wound care, and medicinal fly larvae, along with an oral dewormer called ivermectin
- Survival rates and factors associated with survival and laminitis of horses with acute diarrhoea admitted to referral institutions.
Equine veterinary journal · 2024 · Canada
A group of horses with acute diarrhea was studied to see how many survived and what factors affected their recovery. Overall, 76% of the horses survived, but those with higher levels of certain blood markers had lower survival rates. Interestingly, fewer horses developed laminitis (a painful hoof condition) in Europe compared to other regions, and more cases occurred in the sum
- Effect of phenylbutazone on insulin secretion in horses with insulin dysregulation.
Journal of veterinary internal medicine · 2024 · Australia
Sixteen light breed horses, including seven with insulin dysregulation (ID), were studied to see how phenylbutazone, a common pain medication, affects insulin levels. After treatment with phenylbutazone, the horses with ID showed lower glucose and insulin levels in response to a glucose test compared to when they received a placebo. This suggests that phenylbutazone may help ma
Frequently asked questions
- Can a laminitic horse recover?
- Many do — especially if caught early, the underlying cause is addressed, and the farrier work is excellent. Severe cases with marked coffin bone rotation or sinking carry a much more guarded prognosis and may require months of rehabilitation or, in the worst cases, euthanasia on welfare grounds.
- Is lush spring grass really dangerous?
- For at-risk ponies and metabolically-prone horses — yes. The sugar content of grass peaks in spring afternoons and after frost. Strip-grazing, grazing muzzles, restricted turnout in early morning, and dry-lot turnout are all valid strategies for high-risk animals.
- What's the difference between Cushing's and EMS?
- EMS is primarily insulin dysregulation in overweight ponies and 'easy keepers' across all ages. PPID (equine Cushing's) is a pituitary disease of older horses (>15) causing hairy coat, muscle loss, and secondary insulin dysregulation. They can coexist. The right blood tests sort them apart and dictate treatment.
