ABSTRACT

The skeletal anatomy in particular effectively contributes to the overall shock-absorbing and load-bearing capacity of the forelimb, as well as adding to the overall forward impulse. In the equine antebrachium, it is proposed that a similar relationship between bone strain and fascial construction is present. Both superficial and deep fascial layers are present in the equine antebrachium. The equine forelimb is supported against dorsiflexion when standing, walking, running or landing from a jump by not only the flexor muscles and their derived tendons, but also by the structures acting on the accessory carpal bone. The superficial fascia over the medial aspect of the antebrachium covers the medial surface of the radius as well as the deep fascia encasing the flexor carpi radialis (FCR) muscle. The lacertus fibrosus itself integrates with the deep fascia and, through its connection with the biceps brachii, provides a continuous pathway between the myofascia of the brachium and antebrachium.
