Pre-navicular syndrome

Summary

# Editorial Summary: Pre-navicular Syndrome Caldwell's 1987 research demonstrates that pre-navicular pathology manifests through observable behavioural, gait, and structural hoof changes a full 18–24 months before clinical lameness develops, offering a substantial window for preventative intervention before irreversible navicular degeneration occurs. The study identifies anterior-posterior hoof-pastern axis imbalance (broken-back foot configuration) as the predominant biomechanical driver in most navicular syndrome cases, with medio-lateral imbalances contributing secondarily to heel collapse and progressive tissue loading. Critically, corrective farriery designed to restore proper hoof-pastern axis alignment proved capable of halting disease progression when applied during this pre-clinical phase. Early detection relies on recognising subtle shifts in movement pattern and behaviour rather than waiting for radiographic confirmation; concurrent management demands disciplined corrective shoeing every 4–6 weeks alongside consistent work to optimise musculoskeletal adaptation. For farriers and veterinarians, this underscores the value of systematic pre-purchase and routine lameness assessments to identify at-risk feet before clinical disease manifests, whilst nutritionists and coaches should support the rehabilitation protocol through appropriate conditioning and dietary management during the corrective phase.

Key Findings

• •Clinical signs of pre-navicular syndrome are detectable 18-24 months before obvious lameness appears
• •Anterior-posterior hoof-pastern imbalance (broken-back axis) is the primary factor in most navicular syndrome cases
• •Corrective farriery restoring proper foot and limb balance can prevent progression to navicular disease
• •Early behavioral and gait changes precede radiographic evidence of navicular disease
