Influence of a follower load on intradiscal pressure and intersegmental rotation of the lumbar spine.
TL;DR: A superimposed follower load renders spinal loading with pure moments more physiologic and reduces intradiscal pressure at all levels of the lumbar spine.

TL;DR: The application of pure moments to intact lumbar spinal specimens in vitro produces forces andmoments in implants comparable with loads observed in vivo.

ISSLS prize winner: A novel approach to determine trunk muscle forces during flexion and extension: a comparison of data from an in vitro experiment and in vivo measurements.
TL;DR: In vitro loading conditions can be approximated closely to in vivo conditions with the simulation of an axial preload, local, and global muscles, which provides important input for FEM models, which may then allow the investigation of different load cases.

Computer-assisted surgery in posterior instrumentation of the cervical spine: an in-vitro feasibility study
TL;DR: C1/2 transarticular screws as well as transpedicular screws in the cervical spine can be applied safely and with high accuracy using a computer-assisted surgery (CAS) system in vitro, and may be used in a clinical setting, as it offers improved accuracy and reduced radiation dose for the patient and the medical staff.
Effect of an internal fixator and a bone graft on intersegmental spinal motion and intradiscal pressure in the adjacent regions
TL;DR: The results suggest that disc degeneration, which is sometimes found at the level directly above and below the fixators, is not caused by mechanical factors.
