Summary
# Editorial Summary Whilst MRI-guided medical management of equine foot pain—combining corrective shoeing, rest and intrasynovial anti-inflammatory medication—has become standard practice, long-term outcome data remain scarce. This retrospective analysis of 56 horses treated between 2005-2007 tracked clinical and imaging findings against outcomes ≥12 months post-treatment, with data gathered via detailed telephone questionnaires assessing return to work and lameness persistence. Only 22 horses (39.3%) successfully returned to their previous level of exercise, with a further 11 (32.3%) managed only light riding, meaning nearly 61% experienced poor long-term outcomes; critically, horses presenting with concurrent deep digital flexor tendon, navicular bone and navicular bursa lesions had significantly worse prognosis than those with isolated lesions, and deep digital flexor tendinopathy alone was strongly predictive of persistent or recurrent lameness regardless of other clinical parameters. These findings should temper expectations when counselling owners of horses with multiple concurrent foot structures involved on MRI, particularly those with flexor tendon involvement, and reinforce the importance of realistic goal-setting around return-to-work timelines and athletic demand rather than assuming medical management alone will restore previous soundness levels.

Practical Takeaways
- •Medical management of foot pain has guarded long-term prognosis: expect that 60% of cases will not return to previous performance levels despite treatment with corrective shoeing, rest, and intrasynovial medication
- •Deep digital flexor tendon involvement is a negative prognostic indicator—cases with DDFT pathology are significantly less likely to respond to conservative therapy
- •Multiple concurrent foot lesions substantially worsen outcome; horses with isolated lesions have better prognosis than those with involvement of multiple structures
Key Findings
- •60.7% of horses (34/56) failed to return to previous exercise level due to persistent or recurrent lameness following medical therapy
- •32.3% of horses (11/56) returned to light riding after treatment
- •Deep digital flexor tendinopathy was strongly associated with poor prognosis and persistent or recurrent lameness
- •Horses with concurrent lesions involving deep digital flexor tendon, navicular bone, and navicular bursa had worse prognosis than those with individual lesions
