Episode 103 - Guest: Sharon May-Davis - Grading ECVM (Equine Complex Vertebral Malformation)
ECVM is more than simply identifying an anatomical variation in the lower cervical spine.
In this episode, Dr. Raquel Butler and Sophie Vandenberg are joined by Dr. Sharon May-Davis PhD to explore the history, research and grading of Equine Complex Vertebral Malformation (ECVM), and what different presentations may mean for the individual horse.
We discuss:
🔍 How ECVM was first identified and how the research has developed
📊 How the C6 grading system works and why Grade 4 horses may require further support and investigation
⚖️ The difference between unilateral and bilateral ECVM presentations clinically
🦴 How changes to the longus colli may influence cervical stability, posture and movement
🐴 Early signs to observe including tripping, toe dragging, hypersensitivity and unusual behaviour
✅ Why early investigation, appropriate management and responsible breeding decisions matter
