Cunean Tenectomy-Anyone have this done?

Thanks for the info, gorry details and all! I do have a rather strong stomach, people tell me I should have been a nurse! I am seriously looking into this procedure, it is the last ditch effort I can give him to be comfy. Have had him 6 years and have been through navicular (so I thought and nerved him, grew back sound )terrible suspensory tear on the hind leg that has the spurred hock ,EPSM , AND a fractured coffin bone on the “good” hind leg ! So all have healed well EXCEPT that darn hock, so if I can get that to heal up I will have a sound horse after all of this! If not, he will have a few years being a lawnmower and see if that cures it!
