I have a 6 year old warm blood gelding who had a severe laceration to his tendon sheath in hind fetlock and had acute surgery to avoid infection. The operation went well although the surgeon noted that the annular ligament was severed and therefore decided to remove it altogether. He was placed in a cast after the operation and placed on box rest for a couple of weeks. After this time, the cast was changed to a bandage and placed in a small yard which was followed by daily hand walking. He had significant swelling but the vet surgeon said the prognosis was really good and that it would take about 4 months for recovery. Now, 12 months later he still has significant synovial fluid behind his pastern and around the fetlock area. I feel that an important step was missed with his post-op recovery, the development of scar tissue and constrictions and now we are dealing with that. The vet surgeon told me that he can do a tenoscopy but says the prognosis now is poor. I'm not happy to say the least as I spent significant money on him only as he was giving me a good initial prognosis. He is currently spelling in the paddock and is a happy paddock ornament but is lame 1-2/5. I have investigated different treatment such as shock wave therapy and laser but feel that I can’t justify spending the money on this after what I have already paid. I purchased an ARC microcurrent unit in recommendation but sadly admit after completing the full course, there is no improvement of his injury. I have started working him lightly (ground work and long reining) but he seems more lame afterwards so pulled back on his work. Does anyone in this group have had a luck with the recovery of these injuries? He frequently rests injured leg on his hind toe, so gather he is still uncomfortable.
