ECVM (Equine Complex Vertebral Malformation) is currently a highly debated topic among vets, riders and breeders. It is a congenital malformation of the caudal cervical vertebrae that always involves the 6th cervical vertebra (C6). In some horses the condition includes the 7th cervical vertebra, first thoracic vertebra and the first and second sternal ribs. As a result, the specialized attachment site on C6 for the thoracal tendon of the longus colli muscle is either completely, or partially absent, leaving this muscle without its bony lever (tuberosity) to function normally on the side affected.
These horses may show stability issues with reports of affected horses being potentially dangerous to ride, as they can stumble and fall. Many factors, e.g., concerning management and training, may play a role in the expression of clinical signs. Possible symptoms can be an asymmetric spine, imbalance, coordination problems, lameness, pain, dental problems, signs of stress and behavioral issues.
For manual therapists, the recognition of affected horses is particularly important. Due to the nature of the condition, careful treatment should be considered so not to destabilize the condition further. It is possible that some ECVM horses can be supported, assistance can be provided by providing adequate stability and proprioception training, with a continuance of therapy and bodywork.
It´s often discussed, whether ECVM is more a natural variation or a “pathologic” condition? This question will be answered in this webinar.
