Mechanical Validation of Computed Tomographic Quantification of Posterolateral Intertransverse Lumbar Fusion Available to Purchase

The New Zealand White (NZW) rabbit is often used as an animal model in posterolateral intrertransverse lumbar fusions [1]. Qualitative measures, such as manual palpation and radiographs, have been used to assess fusion mass [1]. However, an evaluation by sacrifice and biomechanical testing is the gold standard for quantitative data. A non-invasive approach to quantitatively assess the mechanics of spinal fusion could allow longitudinal studies with decreased need for animal sacrifice.
