Intervertebral discs serve as essential cushions between the bones in our back, known as vertebrae. These oblong structures are made of a soft gel core enveloped by a tough, fibrous exterior. Over time, these discs may undergo two primary stages of disease. Initially, they can dry out, becoming less functional – a condition called Intervertebral Disc Disease (IVDD). This makes them more prone to herniation, which leads to Intervertebral Disc Herniation (IVDH), causing compression to the spinal cord and associated symptoms.
In humans, a lumbar disc herniation often manifests as intermittent or continuous back pain, which can intensify with movement. In severe cases, such as a significant herniation in the thoracic spine, there may be numbness, stiffness, and weakness in the legs, potentially accompanied by bowel and bladder control issues. More about this can be found on Columbia Neurosurgery’s site.
Dogs, too, are susceptible to this condition. Intervertebral disc (IVD) herniation has become a prominent concern in veterinary medicine, with the last six decades witnessing significant research to comprehend and tackle this debilitating ailment. Brigitte A. Brisson, DMV, DVSc, points out that IVD herniation is a leading cause of neurological issues in dogs, with a notable focus on research over recent years. The symptoms in dogs can vary based on the affected discs. Approximately 65% of IVDD problems relate to the thoracolumbar region of the spine, while about 18% concern the neck alone.
Regardless of the species, it’s crucial to understand that the surgical intervention to treat herniation usually involves removing the bone on one side of the herniated site. The herniated disc material is then extracted, alleviating spinal cord compression. Post-operation, pain and bladder management, kennel rest, and physical rehabilitation become pivotal, especially in canines. More insights on this can be found on the University of Missouri’s VHC site.
To conclude, intervertebral disc herniation is a significant concern for both humans and dogs, affecting quality of life. Early detection and treatment are paramount for the well-being of both species.
