I met the farrier at the barn this morning. Overall, Isis’ feet look good: reasonable growth and plenty of sole and hoof wall. However, she has some bruising in the white line and the white line appears to be thicker.

The white line is actually the growth of the lamina, the part of the hoof that holds the hoof wall to the hoof interior. If the white line is wider (stretching in the lamina: some separation between the hoof wall and the interior hoof structure) or has bruises, then it indicates that some factor has been impacting the lamina. Stressors can include food-related issues (inability to process something in grass, too much food, colic), stressful situations, etc.

The farrier said that he is seeing quite a few horses with the same things showing in their white lines. He thinks it is caused by the lush pastures we have right now. He said to keep an eye on her for a while and monitor the amount of grass or sugars she eats.

Even though the farrier said we should just monitor her white lines, it is still hard to hear that there might be something wrong with her feet. After two boughts with laminitis and losing at least two years worth of riding time because of it, anything abnormal makes me rather twitchy.

Five second summary: Isis had colic surgery today (VERY BAD). I had written a long post about Isis being in the hospital with colic and a slippery-finger mistake caused me to delete the entire entry. It’s too raw to rewrite now.

She was okay at breakfast this moring. The barn manager called me at 9:30 AM, the vet was at the barn about an hour later, and Isis was at the hospital being prepped for emergency surgery by 11:30 or noon. She was out of surgery and in recovery by about 4:30 or so this afternoon. All praises be to close veterinary hospitals.

Isis in the hospital before surgeryOne day she was happy and being her normal playful self. The next she’s lying on her back on the operating table… and you don’t know if she will be there the next day. And this only after a month when she had been showing and doing so well. I’m still in shock…

During the surgery, the vets found a lipoma(1) that had wrapped around Isis’ small intestines. A lipoma is a fatty deposit in her abdomen that, in this case, was suspended from a stalk several inches long. The stalk got twisted around her intestines. On top of that, she part of her large intestine was twisted around, and she had a minor impaction-in-the-making towards her sicum. This type of colic is one of those fluke things that happens. You don’t know when it will strike, or what will happen. It wasn’t caused by any external factors. It was all internal. There was nothing that anyone could have done to prevent this. For being such big, powerful animals, horses are so fragile.

The barn owners were so awesome and supportive. Isis has been boarded at their barn for over eight years. I was one of their first boarders. Isis is like one of their family, just like she is mine. They hauled her in for me and stayed for several hours while we watched her go through tests and surgery.

I’m one of those people who would prefer to watch the surgery instead of waiting some place pacing and not knowing what is going on. As hard as it is to see a horse on her back and her intestines being examined, it’s harder still to be waiting and not knowing. Your imagination has an opportunity to run wild, and that is counter productive, especially when you have to keep your wits about you. I was grateful to the vets for keeping me posted during her surgery and letting me know what they found almost real-time. It was hard to watch, but at the same time, it was a relief to be included in the process.

Keeping focused on getting her care and how she was doing was the only thing that helped me keep my sanity during the day. All I could remember was the last time I’d been on my way to the hospital with a colicky horse. That horse was Isis’ grandmother, Indian Symphony. She died on the recovery table, and left an orphan three-month old chestnut filly (Isis’ dam).

I remembered Symphony’s surgery and the way the small intestines looked grey instead of bright pink. During Isis’ surgery, it was heartening to see that the intestines at least looked pink and had some mobility so they were still functioning. Some of the intestines did look red and aggrevated.

Surgery lasted about four hours. I stayed and watched most of it (except the initial incision, something about that I can’t watch). After she was sutured and closed, she was wheeled into the recovery room. While she was gradually coming around, the anesthesiologist came out and talked to me about her. The two vets who did the surgery also gave me updates. They were all very communicative and helpful. It was comforting and frightening at the same time. They were candid with me, which I appreciated.

They felt that she has a good chance to recover from the surgery (maybe 60%?). One major concern is that she has had laminitis in the past. Any shock or trauma can trigger laminits, as can excess toxins in a horse’s body. The surgery could have both factors. It is possible that she could have some toxicity from the damage caused by the colic. She was given anti-toxin medications as a preventative. Everything that can be done has been done to prevent complications. You just don’t know.

For now, it’s touch and go. I don’t know what will happen. I hope and I pray that my kid will get through this without any problems. Her recovery will be long and hard — 30 days stall rest after she comes home, 30 days small paddock turnout, 30 days pasture rest. It will be much worse than that if she has any complications.

These pedunculated lipomas may entwine around intestine causing a strangulation obstruction. From Terminology Used in Equine Colic, Athletic Animals.

I think I should expand my consulting business to include “horse health specialist.”

With all of the special requirements Isis has for managing laminitis and insulin resistance, I’ve learned more with her than all of the years I’ve had horses. Low carb grain. Grazing muzzles. For months, last year through the beginning of this year, we struggled with keeping the grazing muzzle on her. Finally after we get that to stay on no matter how many times she rubs it against the fence, she trips and falls with me during a lesson… And thus began the second phase of intense frustration. She recovers from the second episode of laminitis, only to trip and fall. We recover from the bruises and scrapes, and then are left wondering why she tripped. Was the tripping caused by muscular-skeletal issues, sensitive feet, neurological problems, or some combination of any of the above?

The one piece of good news was that her problem appears to be muscular-skeletal and sensitive feet, and not neurological (BIG relief). “Team Isis” tried for several months to coincide the farrier and chiropractor visits. It helped, but it didn’t resolve the issue. She still tripped. The only other option was to try using shoes, preferably glue-ons to preserve her feet and not use nails.

Following in the fine tradition established with her grazing muzzle grace, we can’t keep the shoes on her. Yet again, Isis’ shoes are off. And she is ouchy when moving out in the field, near the barn, on almost any hard surfaces. I can’t work her until either she is trimmed again or she has new shoes. The shoes, clips, and glue have to be ordered from different Web sites and take a week or so to arrive. A rush order boosts the shipping to cost almost as much as the shoes.

I’ve had it. I’ve ordered a year’s worth of shoes, glue, clips, and spare tools. No more waiting on orders and losing weeks to waiting on package.

Magazine articles

"Danger in the Grass" in the April 2004 issue of EQUUS magazine. Talks about how an over-abundance of fructans in grass may be related to an increased occurrance of laminitis.

"A Case of Insulin Resistance" by Susan Kauffman in the January 2005 issue of EQUUS magazine, page 29. How a common but litte-known condition similar to Type II dibetes triggered a painful and frustrating episode of laminitis. Excellent reading and background material. This issue is available on the stands now. Highly recommended.

We’ve had some cold weather, so Isis is in a small pasture with grass. Her grazing muzzle is put on every morning. Her new pasture has only a little grass in it, most of it is that light shade of tan that happens after several heavy frosts. The diet paddock she had been in had turned into a mud pit and she was started to get scratches on her heels.

She has been out for about three weeks on partial turnout (day-time only). She has had her grazing muzzle on her full time. Had it on does not mean that it has been effective.

Miss Houdini Horse has figured out how to get it off almost every day. It doesn’t matter what we do with the muzzle, she still gets it off. She has learned how to catch the muzzle on objects and pull it down so either the emergency release breaks or it comes off over her nose.

Additional smaller paddocks are being built for Isis. Ths field Isis is currently in is being divided into two smaller paddocks where she’ll be able to be turned out with minimal grass. The grass in this pasture is very low as it is, but it doesn’t seem to make a difference.

She is still gaining weight. The weight tape doesn’t incidate that it’s more than 16 pounds (969 to 985). However, her crest is larger as are the fat pads along her neck, back, and rump.

I am making more time to work her. I’ve gone out several times this past week during lunch and have ridden and lunged her. This week she has been worked five times, probably a record for me. I just don’t know if it will be enough. As long as it doesn’t rain, I’ll be out there working her.

Here’s hoping that it’s enough to prevent another laminitic episode…

This month’s Equus has an article on page 29 called “A Case of Insulin Resistance: How a common but little-known condition similar to Type II diabetes triggered a painful and frustrating episode of laminitis” by Susan Kauffmann. Physical signs for horses who might be at risk include abnormally distributed fat: crest, whithers, and croup. The horses they have pictured are strikingly similar to Isis’ shape.

Does this mean that Isis has insulin resistance? I don’t know. It’s worrisome because those pictures of horses with this condition really looked like Isis. I’ve asked my vet if we should test Isis.
