When standing, the horse elbow is fixed at approximately how many degrees?

• A. 150 degrees
• B. 180 degrees
• C. 90 degrees
• D. 120 degrees

Answer: (A)

In standing, the forelimb elbow sits in a semi-flexed, relaxed position rather than being fully straight. The joint angle between the upper arm (humerus) and the forearm (radius and ulna) is approximately 150 degrees. This level of flexion provides a stable base for weight bearing while still allowing a bit of give to absorb impact as the horse bears weight through the limb. If the elbow were at a full 180 degrees, the limb would be fully extended, which reduces stability and places more strain on ligaments during stance. An angle around 90 degrees would be too folded and unstable for standing, and 120 degrees would be more flexed than is typical for a resting stance.
