abstract = {Ligament injuries of the cervical spine not only cause
personal limitations for patients, but also have
socioeconomic consequences. There is currently a lack of
studies that comparatively examine all typical cervical
spine ligaments (LSS, LIS, LIT, LF, KL, LLP, LLA) and the
facet joints of the entire subaxial cervical spine (C2-7) in
the three directions of movement (FE, LB, AR) under
continuous load increase. In the present study, this was
done by electromagnetic detection of the change in position
in a load range of ±0.5 Nm under consecutive resections of
the structures. The changes because of the individual
resections are different at the different levels and
directions. The KL and the WB play extensive roles in
limiting movement in the different directions. In contrast,
ligaments in the sagittal plane (LSS, LIS, LF, LLP, LLA)
mainly influence the FE. This is also the direction of
movement most frequently influenced by the individual
resections in a statistically significant way, whereas the
LB and AR are cumulatively influenced the most. Overall, the
following hypotheses can be formulated and specified:1. As
the number of resected structures increases, the BU of the
WFE mostly increases. 2. The direction of movement opposite
the resected structure is most affected, but not
exclusively.3. The BU and the role of the individual
structures vary between the different cervical spine levels
and directions of movement.4. The BU of the WFE of the
subaxial cervical spine increases non-linearly in vitro with
a continuous increase in load. This can be explained by the
increasing stiffness of the ligaments with increasing
load.5. The LIT plays a significant role in the AR of the
C2/3 level. The results presented are relevant both in
everyday clinical practice and in interdisciplinary
research, as they can be used to derive diagnostic and
therapeutic options. This could facilitate future research
and reduce its hurdles by saving human cervical spine
samples. Studies for example in combination with bony
fractures or intradiscal pressure measurement would be
possible to gain further insights and complete the field of
research.},
