What is spondylosis in dogs?
Spondylosis is a degenerative change of the vertebral bodies and the intervertebral discs. Bony growths occur on the underside of the vertebral bodies on the one hand. To remove elastic elements on the other hand.
Function of the spine:
The spine is divided into five areas:
– cervical vertebrae – thoracic vertebrae – lumbar vertebrae – sacrum – caudal vertebrae
These areas consist of individual vertebrae. Each vertebra has its function and is adapted accordingly in shape and appearance.
The spine has u.a. the task:
– to protect the spinal cord – to distribute the prere on the individual vertebrae – is the support and carrier framework of the locomotor system – holding and suspension framework for the internal organs
At a walk, the spine swings from the shoulder to the hip in an S-shaped motion from back to front. However, if the spine does not vibrate, movement restrictions are present.
The stress on a vertebra is particularly high at certain nodes:
The cervical and lumbar vertebrae are very mobile, while the thoracic and sacral vertebrae are rather rigid. Thus, the last vertebra or. the last disc of the mobile section does not simply pass on a movement to the next vertebra, but must buffer it, because the following part, the rigid section, cannot absorb this movement. These areas are therefore more prone to spondylosis. Pathologically, it is purely a protection of the body. Because the bony spikes that are formed by the body there, take the prere off the intervertebral disc and can thus stabilize or. Compensate.
The older the dog, the more the discs and ligaments lose elasticity. Certain movements are more difficult for the older dog than for the young dog.
What symptoms does the dog show with spondylosis?
Spondylosis occurs in all breeds of dogs, with Boxers having a significant breed disposition. Since spondylosis rarely causes actual clear symptoms, spondylosis is often diagnosed as an incidental finding.
When discomfort occurs, it is usually when individual vertebrae begin to form bridges. D.h. when the vertebral bodies are not yet completely ossified with each other. If the vertebral bodies are not yet ossified together, spur- or bridge-like bone formations cause irritation of the periosteum, which is very painful.
At this stage the dogs react!
Have difficulty standing up, avoid climbing stairs, and dislike jumping. The back may also be significantly curved up due to the pain. Once the ossification of the vertebral bodies is complete, the stiffening of the spine leads to the cessation of bone irritation and thus to the cessation of pain. These deformities can be quite severe. In the lateral region of the vertebral body also go up to the nerve exits. In very extreme cases, entire spinal segments are rigidly connected to each other by a massive bony bridge.
