Short Ulna Syndrome
Posted: Sun Dec 09, 2012 12:08 am
Hi, I wonder if anyone can guide me on what rubrics to consider please...
On 31st August a female puppy was found on the streets of Bulgaria at around 5 weeks old with her front left leg injured (metacarpals) the vet suggested it was most probably squashed under something heavy. It wasn't broken, and resting seemed to heal it.
30th October - Unfortunately against my advice, she was vaccinated by her rescuer for DHPPi and Rabies (together as a combination vaccine).
9th November - She then broke the same front left leg, at the bottom growing plate (above the original injury), with no real reason, no fall or anything.
The break itself seemed to be healing well, yet the leg started to twist within days of the break (perhaps had even started before). Vet opinion is that the ulna has stopped growing while the radius continues to grow, so the radius has begun bowing at the top, rotating outward and suffering "valgus deformity," which is a twisting of the leg away from the midline of the dog's body. They think the start of this twisting was the cause of the break.
This `short-ulna-syndrome' is said to be most commonly caused by some traumatic injury to the affected limb of a young puppy which fits with the history that we know. Trauma can apparently damage the blood vessels that normally provide the blood supply necessary for bone growth.
So, I am sure that her "Never Well Since" is the original trauma to her veins on that leg when they were most likely crushed, and I am sure that this created a weakness. What's weird to me is the change in speed of developments - she was 2 months without visible twisting, she broke her leg and then the twisting showed very quickly. So I'm wondering if it is possible to be vaccine related even when the vaccines were given only 9 days prior.
I'm also struggling on the rubrics for the actual twisting, I can't find anything specific for it other than a small rubric for Twisting, sensation of.
All help very much appreciated!
