The biomechanical effect of lumbopelvic distance reduction on reconstruction after total sacrectomy: a comparative finite element analysis of four techniques

The lumbosacral complex serves as a biomechanical keystone, transmitting the forces from the axial skeleton to the lower limbs [1,2]. It plays a crucial role in maintaining an upright posture and enabling the ability to walk [3]. If this anatomical junction is affected by primary malignant sacral tumors [4 –6], surgical interventions invariably emerge as the preferred treatment strategy. However, the surgical treatment of sacral tumors is technically demanding and necessitates careful consideration of anatomical and biomechanical factors [2,7,8].
