THORACIC vertebrae, BONE mechanics, SEGMENTAL analysis technique (Biomechanics), BIOMECHANICS, and SKELETON
The article presents a study on how the motion segment flexion stiffness is affected by the posterior thoracic spine anatomical structures. The study used 23 thoracic motion segments that were collected from 6 human cadavers, and underwent biomechanical testing. Results of the study reveal that one of the factors that contribute of the adjacent segment flexion stiffness is the posterior thoracic skeletal structure involved in upper instrumented vertebra exposure andanchor placement.
