High Suspensory Ligament Injuries in Horses

Interesting article on suspensory ligament injuries. Note the last sentence in the quote below. I wonder if any of the nonresponsive horses were examined for DSLD/ESPA according to Dr Mero's protocols.

High Suspensory Ligament Injuries in Horses: "While shock wave therapy is able to help most of the non-resolving cases, there are specifically difficult situations. First, older horses seem not to respond as well to therapy and in my experience seem prone to re-injury. Second, horses with hind limb high suspensory injuries are often career threatening. While the horse can return to a reasonable degree of athleticism it is often at a lower level than where they were at the time of injury. And finally, horses with progressive chronic dropping of the fetlock are often not responsive to therapy."
