It has been a long time.
I keep starting to write an entry and stopping. I am still in a muzzy
state of unrest from the recent diagnosis I received for Deli. Unrest and heartbreak.
A couple of months ago after a long-but-slow conditioning ride, Deli
presented with some pretty severe back soreness. This was much worse than the
muscle soreness she had after her first LD at Mt. Adams. I thought, at first,
it was related to a new pad combination I’d tried (since that was the first
long ride with the new pad configuration). Then, when it didn’t resolve as
expected, I wondered if she had hurt something while bouncing around in the mud
trying to avoid a water crossing.
Long story short of it, we’ve been chasing odd back soreness in her
lower lumbar region since then. I finally decided to get a back ultrasound
after the normal R&R, chiropractic adjustments, and acupuncture did not
make a difference. She would get better, but then I’d do an easy ride and the
back soreness would flare up again.
Well, the news from the ultrasound was not good: kissing spines and
some serious damage multifidus muscle along her spine – right behind her
withers.
What is kissing spines? The more technical phrase is “overriding dorsal spinous
processes” – essentially this term describes the touching or “kissing” of spinal processes, which are the long thin
bones that protrude upward from each vertebrae in horse’s back. It’s likely
she has always had this underlying problem because she has always over-built
her lower back muscles. Her conformation (that high-headed saddlebred set) likely
predisposes this problem in this area of her back. The damage to the multifidus
could be acute or chronic. Regardless, time carrying a rider and the increased
workload we have had coming into endurance riding has made an underlying
pathology become more obviously painful.
You want to get technical? Here are some ultrasound images.
Normal
multifidus muscle fiber pattern with some underlying
proliferation of bone on a dorsal spinous process. 13th
thoracic.

Damage
to/atrophy of the multifidus muscle as it courses from one spinous process to
the next. Notice the total loss of normal fiber pattern compared
to the previous image.
|
Location
where dorsal spinous processes are close-riding or touching. Approximately 13th-15th dorsal spinous processes.

In the short term I am working with Deli to try and get her back to
lift (by using her abs) in that upper back region. So far, the therapies and
ground exercises I’ve tried have been unsuccessful. Our next step is to try mesotherapy, a pain-dampening technique that
stimulates the mesoderm, the middle layer of the skin. Our hope is that pain
relief will make her more able to build the muscles needed to relive those
spinous processes. We are also going to get a theraband (a lounging therapy
tool) and continue with massage, acupuncture, and chiropractic work.
In the long term… any more endurance riding is probably out of the question for her. For this, I am heartbroken. She really showed she has the mind and enjoyment for it and I know this is the sport that I want to be involved in over any other.
Then I will need to get a new saddle. Though the edema I was getting with my Ghost saddle didn’t appear painful to palpation, you could see in the ultrasound that it was not superficial and may have been contributing to the multifidus damage and internal pain. I am considering doing the Reactor panel “rent for rehab” program, but the cost of all of that makes me cringe.
As of right now, if after a couple months of ground therapy it does not look like Deli will be able to be decently sound and comfortable for trail riding I am going to retire her altogether. It’s rough and my heart aches because she is my heart and the one I want to go off and have adventures with. But this pathology means I can’t rely on her comfort. And if it will take 10 hours of doing hard arena work she hates just to get an hour on the trail... I’m not sure that’s worth it. Especially if that would require me buying her a $4k saddle that would set back my financial situation. It will make her so very unhappy. And she isn’t that horse that has a huge work drive – she would be perfectly happy being a pasture puff.
On the other hand, if she has just been annoyed by arena work because of this underlying condition the whole time, she may thrive under these therapies. Not enough to do endurance, I’m sure, but it might be enough to justify not retiring her (in part because this condition is chronic and will progress even if she is a pasture puff, and proper work might help her longevity).
I don’t have to make any decisions yet, but having a “if, then” plan is necessary for me to not otherwise implode from stress. We still have some things to try, but I am preparing myself for the idea that Deli is going to be retired sometime soon.
