Transpedicular screw fixation is a gold-standard treatment for degenerative lumbar spine and bursting fracture because it involves three columns of the spine and achieves stabilization1,2. However, most patients who undergo such surgery also have osteoporosis3,4. Many studies have evaluated the fixation strength and the osseointegration status of transpedicular screws, because the loosening of pedicle screws currently in use has been reported in patients with osteoporosis5,6.
The porcine spine is similar to the human spine in terms of size. It is less expensive compared to a primate model7. Furthermore, an in vivo mechanical study has demonstrated that the quadruped porcine spine is essentially loaded in the same way as that of the human spine8, which is why many researchers use porcine spines for studies on the prevention of pedicle screw loosening. However, it takes several months to study pedicle screws in the porcine spine because identifying the long-term stability of pedicle screws takes times. In order to compare different types of screws in the vertebral body, it is necessary to insert the screws in similar positions. Therefore, researchers should be well-acquainted with proper anesthesia techniques, standardized surgical protocols, and harvest procedures before performing any experiments. Here, we describe a detailed method for anesthesia, surgery, and harvest for the evaluation of pedicle screw fixation using a porcine spine model, including ex vivo imaging, histology, and strength testing.
