Project descriptionThe hydration behaviour of the disc is highly dependent on its volume and biochemical composition. The aim of this project is to measure the steady-state hydration profiles of spine segments and the micromechanical properties of the interlamellar matrix in the disc annulus fibrosus for future research using various animal species. Data will be compared to human discs. Spinal level will also be compared; i.e. samples from lumbar, thoracic and cervical spines. Species: Human, Sheep, Pig and Cow.
