Abstract/Summary An immature calf spine model was used to undertake anatomical and biomechanical investigations of an anterior vertebral staple used in the thoracic spine to treat scoliosis. The study involved three stages: (1) displacement controlled testing to determine changes in bending stiffness of the spine following staple insertion, (2) measurement of forces in the staple using strain gauges, and (3) micro-CT scanning of vertebrae following staple insertion to describe the associated anatomical changes. The results suggest that the mechanism of action of stapling may be a consequence of hemiepiphysiodesis causing convex growth arrest, rather than the production of sustained compressive forces across the motion segment.
