Equine laminitis · clinical decision support

The biomechanical model the textbook prescribes,
at the speed your clinic needs.

A clinical tool for qualified farriers and equine veterinary surgeons. It captures the measurements you already take and applies a compound palmar-angle and P3-rotation model to calculate a prescriptive heel-elevation protocol, returning a defensible multi-limb prescription in seconds. See the calculations.

Laminitis Tool is the critical decision-support mechanism for informed podiatric interventions, and the sibling to HoofFlix's learning content — videos, courses, webinars, podcasts and research articles for equine veterinary surgeons, farriers and therapists. Watch a laminitis case study on HoofFlix; apply the protocol with this tool the next day.

What it does

From radiograph to prescription, in the same workflow.

Designed to replace the paper, calculator, and three open tabs you currently use to assess a laminitic case. Every output is justified by a documented biomechanical formula, not opinion.

Radiograph markup

Tap landmarks directly on lateral and DP radiographs. Solar photographs too. Per-limb. The tool computes rotation, sole depth, sinking, palmar angle, and dorsal wall thickness from your taps — no manual algebra.

Compound-PA model

Caldwell & Madden's compound-PA model is built in and calculates automatically from your radiograph markup. When PA exceeds 5°, the engine activates the secondary correction pathway — effective angle, excess PA and lamellar lever all derived live as you adjust inputs.

F9 heel-elevation protocol

The heel-elevation model derives from tendon and laminar-tension formulae and the published work of O'Grady & Steward, combined with clinical geometric proportionality, to form the prescription baseline (see the calculations). The engine caps at 6 mm and surfaces every safety boundary, including tenotomy reduction mode for post-surgical rehab.

Multi-limb workflow

Capture all four limbs in one case. The output aggregates eligible limbs into a single prescription, surfaces cross-limb patterns (forelimb asymmetry, fore-dominant lameness), and prints a unified report.

Prescription + report

Auto-built farriery prescription card: breakover position, rim-pad spec, clog version, and the maximum Shore-A hardness for supportive materials — derived from hoof-wall and sole modulus-of-elasticity calculations, adjusted for horn quality, surface footing and clinical geometric proportionality. One-tap PDF report to share with the attending vet or file in case notes.

Offline-capable PWA

Install to home screen once. Works in barns, yards, and at the side of a horse with no signal. Cases sync back to the cloud when you reconnect. 60-day persistent sessions.

For whom

Built for qualified professionals.

The tool is restricted to clinical use by qualified practitioners. Outputs are analytical, not diagnostic — clinical judgement remains with the attending veterinary surgeon.

Farriers

Defensible prescriptions you can show to the attending vet or the horse owner, anchoring every recommendation in published biomechanical formulas instead of "the farrier just guessed". Plus automated case recordkeeping for professional liability and insurance: each report lists the recommendations to review at the next treatment cycle and records the outcome for comparative analysis.

Equine veterinary surgeons

Faster triage on laminitis cases — sinking risk, cast indication, sole emergency thresholds all surfaced automatically. Generates the prescription you would have asked the farrier to follow anyway.

Equine therapists & students

The five engine-verified reference cases (Bella, Midas, Duchess, Apollo, Copperfield) cover the textbook presentations from prophylactic through critical sinking. Free to explore, no signup, at /demos.

How it works

Six steps. About ten minutes per case.

The clinical workflow tracks the conversation a farrier or vet already has with a horse: declare intent, capture the patient, observe, measure, interpret, document. The tool removes the manual arithmetic and the cross-referencing, not the clinical judgement.

Authority

Built on published clinical science.

Every formula in the engine is byte-identical to Mark Caldwell's reference implementation, automatically verified on every release. The compound-PA model is from The Equine Foot Vols 1–2 (Caldwell & Madden, 2025). The F9 protocol is the AAEP-published work of Stephen O'Grady DVM and Andrew Steward (2007/2009).

"This is the tool I wished I'd had on my first laminitis case. It encodes every clinical judgement I make into a defensible workflow that any qualified farrier or vet can use the same way."
