Summary
# Editorial Summary Chronic coronary band avulsions present a significant reconstructive challenge in equine practice, yet surgical management options remain poorly documented in the literature. Markel and colleagues treated three adult horses with coronary band avulsions of markedly different chronicity (2, 3, and 46 months), each presenting the characteristic deformity of aberrant horn growth perpendicular to the hoof wall and a visible coronary band defect. Following surgical reconstruction under general anaesthesia, all three horses demonstrated complete healing of the avulsed coronary band, with follow-up evaluations extending 12–23 months post-operatively. The primary cosmetic sequela was mild surface irregularity of the hoof wall distal to the original injury site, suggesting that surgical repair can restore coronary band integrity and normalise subsequent horn production even in longstanding cases. These findings indicate that surgical reconstruction warrants consideration as a viable treatment option for chronic coronary band injuries, particularly where functional or aesthetic concerns motivate intervention, though the small case series emphasises the need for further investigation into optimal timing and technique.

Practical Takeaways
- •Surgical reconstruction is a viable treatment option for chronic coronary band avulsions, even in cases with prolonged durations (>3 years)
- •Long-term outcomes are favorable with complete healing achievable, though mild cosmetic hoof wall irregularities may persist
- •This technique should be considered when managing chronic coronary band injuries affecting hoof quality and function
Key Findings
- •Surgical reconstruction of chronically avulsed coronary bands resulted in healing in all 3 horses
- •Avulsion durations ranged from 2 to 46 months prior to surgical intervention
- •Follow-up evaluation at 12-23 months post-surgery showed successful coronary band healing
- •Mild roughening of the hoof wall distal to the previous avulsion site was the only observed complication
