Kissing spines can cause severe pain and seriously affect a horse’s performance. Find out what the signs are and how it can be treated...
A horse with kissing spines is thought to feel consistent, low-grade pain from its back because the spinous processes (the sections of bone that point upward from the main vertebrae that carry the spinal column) press against or rub on each other during movement.
The bones with the spinous processes run from the first thoracic vertebra (T1) at the horse’s withers to the last lumbar vertebra (L6) at the point of the hip, with the T13 to T18 bones being the most commonly affected. This is the area where the saddle and the rider are located.
