GG and Cora
Saddle-related swelling on the spine
After spending nearly fifteen years exploring the horse’s back, it’s unusual to see pathology that I’ve
never seen before. Last Saturday, that’s exactly what happened. Here's the entire story...so far.
History
A little more than a week ago, I received a call from a local rider,
GG. She recently acquired a Tennessee Walker mare, Cora. The mare came with a
raised area on her back but it didn’t seem painful, nor did it concern the veterinarian
who conducted the pre-purchase examination.Next,
GG spent quite a bit of money on a really good western saddle with the
intention of keeping Cora as comfortable as possible. Thinking all was well, GG
was quite distressed when she finished a trail ride and removed her supposedly
well-fitting saddle to find a contusion on Cora’s spine, right on top of the existing lump. She evaluated the area
and concluded that the screws in her flex-tree saddle had pressed directly onto
the spine, creating the damage. She asked me to come determine why this saddle
didn’t fit, and what Cora might need instead.
Initial Examination
I arrived at the barn to meet Cora, a petite mare with a
visible swelling at the thoracic-lumbar junction. This is the spot on the loin
of the horse where the thoracic vertebrae end and the lumbar vertebrae begin. Pressing
on the bump gave the sense of something popping, as though there were nitrogen bubbles in
the tissue. The feeling is similar to the crunch of compromised cartilage that
can be felt in many aging human knee joints. The mare was not particularly
sensitive to palpation of and immediately around the swelling, but did have a mild painful reaction in the Latissiumus Dorsi, or the long back muscles, on the left
side of her body. I have never seen a presentation like this before, and had no
idea if the problem was primarily muscular or primarily skeletal. Because she did not seem to be in significant pain, we proceeded
with the fitting.
Cora’s Saddle Fit Problems
When we examined Cora’s saddle, we found that the tree
angles were a poor fit for her shoulders; the tree was too long for her short
back, and it was too flat from front to back, resulting in bridging. We were
able to find a substitute saddle owned by one of GG’s friends which addressed
all of these issues: the tree angles were correct and so there was room for the
shoulder; the tree had more rock and so followed the curves of Cora’s back, and
the saddle was shorter and so did not extend back past the last true rib.
A Good Pressure Test: Not the whole answer!
We saddled Cora with the test saddle and our Port Lewis
Impression Pad to conduct a pressure test of the borrowed saddle. GG rode for the 20 minutes required
for a test and I had the opportunity to watch Cora move. She seemed to be a
rather tense member of the Walker family, keeping her head fairly high and neck
and back tense while she was ridden. She was extremely forward, sometimes even
frantic it seemed, scrambling a bit as she rounded corners of the small arena.
GG is a balanced and confident rider. The pressure test showed a very even
distribution of weight under the saddle with no obvious pressure points.
After unsaddling Cora, I checked the swelling on her back
and found that the “crunchy” area, formerly quite small and fixed, was now
quite diffuse. The nitrogen bubble effect could now be felt while palpating an
area 2” in any direction around the swollen area. It appeared that the pressure
of the saddle pad directly on the swelling had caused this effect and we
contemplated cutting a large hole in the saddle pad so that were would no
longer be pressure directly on the spine. However, before we could do this…
The ReactorPanel Difference
…we decided to try a ReactorPanel saddle on Cora. Though GG
has only ridden western in the past, she was curious about our saddles and how
they work. Right away GG was
intrigued by my ability to create a wide gullet in the rear of the saddle so
that I could avoid putting pressure near the damaged area. She got on
for a test ride, and after feeling Cora stretch her neck out, relax her back
and go extremely quietly and calmly, GG had to give me a hug on my way out of
the barn. The transformation was amazing!
Current Status
At present, we do not have a diagnosis for Cora’s back
problem. Because it’s so unusual, I’ve
requested to remain involved during the process of exploration with local
veterinarians. I also reached out to my friend and brilliant diagnostician, Dr.
Kerry Ridgway DVM who provided excellent advice (if anyone reading this would
like to know more about the back-and-forth discussions, please email me).
GG has been riding in the ReactorPanel VSD Summit, and is
very pleased to report that the swelling on Cora’s back has gone down quite a
bit and is, in fact, the best it’s been since she got the horse. She has written
me several very touching emails detailing their progress together. While she
knows that she has more research and work to do, she clearly expressed her
happiness and gratitude for being able to improve her horse’s quality of life through better saddle fit.
Next Steps
I will be attending the meeting with local vet Dr. Diane
Isbell for an ultrasound examination tomorrow afternoon, and will keep
monitoring GG and her progress with her RP saddle trial. I’ll update this blog
with the results of both events!
