Kissing Spines — More Common Than You Think
Kissing Spines (also known as Overriding Dorsal Spinous Processes) is a condition that affects many horses — sometimes without us even realizing it. It occurs when the bony spines along the horse’s back are too close together, causing pain, inflammation, and even behavioral changes.
Signs can include:
⚡ Resistance under saddle
⚡ Bucking, rearing, or refusing to move forward
⚡ Trouble with bending or collecting
⚡ Changes in temperament or sensitivity when grooming the back
⚡ Reduced muscle over the top-line
The good news? With the right diagnosis, management, and rehabilitation, many horses with Kissing Spines can return to comfort and performance. 💪
At Vet in the Valley, we take a thorough and thoughtful approach to diagnosing Kissing Spines. Each case begins with a comprehensive soundness evaluation to rule out or identify any contributing lameness issues using our lameness locator SLEIP. From there, we use radiographs (X-rays) and ultrasound to assess the spacing and alignment of the dorsal spinous processes along the spine.
In some cases, we may also perform diagnostic nerve blocks of the back to confirm that the area is indeed the source of discomfort.
This step-by-step process ensures we get the clearest picture possible — helping us create the most effective, individualized treatment plan for your horse. 🐎
If your horse is showing signs of back discomfort, it’s always worth having a professional assessment — early intervention can make all the difference. 🐎
