Complex vertebral malformation(CVM)
Also known as: Congenital Vertebral Anomalies · Wirbelkörperfehlbildung · Angeborene Wirbelfehlbildung · Keilwirbel · Wedge vertebrae · …
Overview
What it is
Complex vertebral malformation is a congenital condition where the bones of the spine, known as vertebrae, do not develop properly during fetal growth, sometimes resulting in abnormally shaped bones like "butterfly vertebrae." This structural defect affects the skeletal system and can put pressure on the spinal cord, which is the main nerve pathway running down the back.
How it presents
Owners typically notice symptoms within the first year of a puppy's life, which can include a visibly curved spine, uncoordinated walking, weakness in the hind legs, or difficulty standing. In severe cases, the pressure on the spinal cord can lead to paralysis.
Treatment
While the underlying bone malformation cannot be cured, symptoms can be managed through lifelong pain relief, physical therapy, or a one-time corrective surgery to relieve pressure on the spinal cord. Depending on the chosen approach, treatment costs typically range from 1,000 to 6,000 EUR.
