Context of the project:
Intervertebral disc disease (IVDD) is the most common spinal disease in dogs and is also seen occasionally in cats. The most common spinal surgery performed in the dog is for intervertebral disc disease.
Intervertebral discs are fibrocartilaginous cushions between the vertebrae (except the first two cervical vertebrae) that allow movement, are supportive and act as shock absorbers. They consist of a fibrous outer rim, the annulus fibrosis, and a jelly like centre, the nucleus pulposus. Intervertebral disc degeneration results in diminished shock-absorbing capacity, and can ultimately lead to disc herniation and spinal cord compression.
To treat degenerative cases e spinal device is inserted (figure 1). However, such device increase dramatically the stiffness of the spine, compromising the pet motion and daily activities.
The aim of the activities is to develop a model of the spine of the dog and validate using experimental activities data present in the lab. Once the model is validated the students need to develop a spinal device and to optimize the design in terms of spinal flexibility.
The study will be performed using finite element analysis.
