The leading reason for chronic hind leg lameness is call “bone spavin”. Equines with bone spavin can have any of the following symptoms. They can be sore along the muscles on either or both sides of the spinal column. They can come out of the stall stiff however “work out of it” as they exercise. They could stumble a lot behind or begin having problem coming below themselves to do dressage work. They might have trouble decreasing hillsides on tracks. Other steeds might start refusing jumps where as soon as they were very willing. Western steeds could show difficulty doing sliding stops or spins off the hind legs.
When analyzed, these equines can be positive to hind leg flexion tests. This includes lifting and bending the hind leg by grasping the cannon bone and bending the hock. The leg is held in this position for 1 minute and the equine is jogged off. A positive flexion test is when the equine limps during the first couple of steps following the flexion test, or refuses to trot and burglarize a canter. When lifting the hind leg and pressing the within splint bone, they will certainly frequently raise their hind leg like a canine. While in motion, these equines tend to land the affected hind legs in toward to the center. This is in an effort to bear weight on the outside of the leg.
