INFLUENCE OF KYPHOSIS ON SPINAL LOADING G. Spreiter 1 , P.F. Heini 2 , P. Galibarov 3 , S. Dendorfer 4 and S.J. Ferguson 1 1. ABSTRACT Osteoporosis affects an estimated 75 million people in Europe, USA and Japan. The biggest risk of fracture is in the spine. Literature shows that an excessive thoracic curvature is an important risk factor for future fractures. The objective of the present study was to evaluate the influence of kyphosis on local spinal segment loading, using a numerical musculoskeletal model. This study extends a previous musculoskeletal model of the spine to include the multi-axial stiffness of all lumbar and thoracic intervertebral discs (6 DOF). The model was constructed with the AnyBody Modeling System. The improved model incorporates intra-abdominal pressure and lumbar ligaments inherited from the base model. The simplified thorax model has been refined, adding individual thoracic vertebral bodies to allow the degree of kyphosis to be altered. The multifidus and semispinalis muscles for the thoracic spine have been added. Segmental compression and shear forces were compared for three different kyphosis severities (37°, 50°, 70°) during simulated box lifting. Simulation results for these different kyphosis severities showed good agreement with literature for compression forces between T6 - T9. The most severe kyphosis curvature lead to an increase in segmental compression forces at these levels of up to 20%, compared to the model with normal curvature. For a moderate kyphosis curvature, the increase in compression was approximately 10%, compared to the normal curvature. This study has demonstrated that increasing kyphosis is associated with higher compression forces between T6 - T9, and therefore may increase the risk of vertebral fractures. 2. INTRODUCTION Osteoporosis affects an estimated 75 million people in Europe, USA and Japan. The biggest risk of fracture is in the spine. A 50 year old woman has a 16% lifetime risk of experiencing a vertebral fracture [1]. Literature shows that an excessive thoracic curvature is an important risk factor for future fractures, even independent of low bone mineral density or prior fracture [2,3]. Recently, the influence of sarcopenia, the agerelated decrease of muscle volume and quality, has been implied to be also a potential risk factor. This is based the work of Sinaki M. et al. [4], who has shown that stronger back muscles reduce the incidence of vertebral fractures in estrogen-deficient women. However, the relative importance of these factors is unknown and, therefore, the goal of this study was to evaluate the influence of kyphosis and sarcopenia on local spinal segment loading, using a numerical musculoskeletal model. For a comprehensive spinal musculoskeletal model, the inclusion of passive soft tissue structures seem to be 1 Institute for Biomechanics, ETH Zürich, Zürich, Switzerland 2 University of Bern, Bern, Switzerland 3 AnyBody Technology, Aalborg, Denmark 4 Regensburg University of Applied Sciences, Regensburg, Germany
