The position and orientation of the probe during minimally invasive procedures in the cervical spine are important factors in monitoring the local pressure profiles in the mobile synovial joint, according to a study published in Spine.
Researchers evaluated the influence of the position and orientation on probe measurements in companion surrogate and cadaveric investigations. They placed the probe in the facet of an anatomic vertebral C4/5 surrogate undergoing sagittal bending movements. The contact regions in the joint were mapped by pressure sensitive paper.
While the experimental and theoretical pressure profiles follow the same trends, the measured maximum pressures were half of the theoretical ones. The maximum pressures in the orientation study were not different for probe orientations of zero degrees and five degrees, and no signal was recorded at orientations more than 15 degrees.
