White line disease in a 19-year-old appendix mare.

Abstract: A 19-year-old appendix mare was presented with severe, acute right forelimb lameness and a history of significant hoof wall defect. The defect began as progressive toe separation affecting the dorsal hoof wall, which was eventually resected by a farrier. Placement of bar shoes by a farrier to stabilize the hoof was ineffective. Radiographs showed hoof wall separation, palmar rotation, and displacement of the coffin bone, consistent with failure of the laminar structures. Treatment included phenylbutazone, radiographic-guided therapeutic farriery consisting of derotation with a wedge shoe, and restriction to a small, dry paddock. Maladie de la ligne blanche chez une jument Appendix âgée de 19 ans. Une jument Appendix âgée de 19 ans fut présentée avec une boiterie aiguë sévère de la patte avant droite et une histoire de défaut significatif de la muraille du sabot. Le défaut débuta comme une séparation progressive de l’orteil affectant la paroi dorsale du sabot, qui fut éventuellement enlevée par un forgeron. La mise en place de fers fermés par un forgeron pour stabiliser le sabot s’avéra inefficace. Des radiographies ont montré une séparation de la muraille du sabot, une rotation palmaire et un déplacement de l’os du pied, compatibles avec une défaillance des structures laminaires. Le traitement a inclus de la phénylbutazone, des ferrages thérapeutiques guidés par radiographie consistant en une dérotation avec un fer angulaire et restriction à un petit paddock sec.(Traduit par Dr Serge Messier).

The research article is about a case study of a 19-year-old appendix mare with severe hoof disease, detailing its symptoms, diagnosis procedures, and treatments.

Objective of the study

  • The main objective of this study was to investigate and document a practical case of White Line Disease in a 19-year-old appendix mare. The researchers sought to trace the progression of the disease, from the onset of symptoms to the diagnosis and the subsequent treatment.

Description and progression of the disease

  • The mare was initially presented with an acute lameness in the right forelimb. Further examination revealed that the mare had a significant defect in its hoof wall. The defect first appeared as a gradual splitting of the toe, which affected the dorsal hoof wall. Over time, it was removed by a farrier.
  • Attempts to stabilize the hoof by placing bar shoes were ineffective. Radiographs taken afterward revealed hoof wall separation, rotation at the back of the foot, and displacement of the coffin bone – all signs pointing toward failure of the laminar structures within the hoof.

Treatment

  • Treatment for this case involved administering phenylbutazone – a commonly used nonsteroidal anti-inflammatory drug in veterinary medicine. Additionally, radiographic-guided therapeutic farriery was implemented. This treatment involved using a wedge shoe to aid in derotation of the hoof.
  • Lastly, the mare was confined to a small, dry paddock. This was done to minimize further damage to the hoof by reducing activity and mitigating exposure to moist conditions which could potentially worsen the condition.

Conclusion

  • This study provides insights into a practical case of White Line Disease in horses. It reveals the symptoms, diagnosis, and treatment options, beneficial for veterinary practice. Additionally, it helps in building a record and understanding typical cases, which can aid the diagnosis of similar instances in the future.
