Kissing spines are likely acquired. They can be the result of a variety of factors, including poor saddle fit and improper training that allows the horse to carry itself with its head up, back hollow, and not engaging the muscles in its core. Genetic factors are possible, but none have been identified to date.

What is the difference between C spine and L spine?
The lower five vertebrae from the ribs to the sacrum constitute the lumbar spine. They form the largest vertebrae in the spine.

What is C and T spine?
(Spinal CT Scan, CT of the Spine or Back) Computed tomography (CT scan or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body.
What animals have no spines?
Animals without backbones are called invertebrates. They range from well known animals such as jellyfish, corals, slugs, snails, mussels, octopuses, crabs, shrimps, spiders, butterflies and beetles to much less well known animals such as flatworms, tapeworms, siphunculids, sea-mats and ticks.

Can you replace spines?
Severe fractures are unstable and often require surgery to remove and replace the damaged vertebra and stabilize the spine. A lumbar vertebral body replacement involves replacing the affected area with a small metal cage filled with bone graft material, which is then screwed into the adjacent healthy vertebrae.
