Abstract
Only little is known about the loads acting on internal spinal fixatio n devices. The forces and moments for different external loads were no w measured using instrumented implants. Measurements were performed on intact cadaver spines and after a corpectomy. Additionally the influe nce of the mounting accuracy on the distribution of the loads in the f ixators was investigated. It could be shown that the implants are not loaded symmetrically. After a corpectomy the loads on the implants are significantly higher than for an intact spine.
