Then the CSA was determined during supine axial compression in slight extension (ACE), obtained with a specially designed loading device. A measurement error study was performed.A minimum difference in CSA of 15 mm2 between PRP and ACE was found to be significant. In 40/50 (80%) of CT-...
This structural adaptation achieves lightness by its porous network with strength in tolerating greater peak strains (not stresses) compared with cortical bone; the trabecular structure is able to withstand large deformations to facilitate flexion, extension, and rotation of the whole vertebral skeleton ...
Importance Axial spondyloarthritis is an immune-mediated inflammatory condition involving the sacroiliac joints, spine, and peripheral joints. It affects approximately 1% of adults in the US and is associated with impaired physical function and reduced quality of life. Observations Inflammatory chronic back...
many surgeons suspect that they are related to the damage of cervical extension mechanism and the decrease of cervical activity.There is no efficient treatment for axial symptoms nowadays,many researchers reduce the incidence of axial symptoms by improving the traditional posterior C3～ C7 laminoplasty....
The cervical spine is important to consider in positioning the head in space. The dominant motion in the lower cervical spine is flexion-extension, but the cervical spine's anatomy permits a fair amount of motion in all planes. In high-speed injuries, the head can act as a significant lever...
When we lengthen the spine, we are creating axial extension- creating more space between each of the vertebrae in the vertebral column.Which bones are in the axial and appendicular skeleton?Axial and Appendicular Skeletons The axial skeleton forms the central axis of the body and consists of the...
A pure moment of ±2.0 N-m was applied to the specimen in flexion-extension, lateral bending, and axial rotation. Range of motion (ROM) and neutral zone were calculated for the C6-7 segment. Results: ROM was reduced significantly compared with the intact or injured condition for 3 ...
The yield load of this segment, and of the whole member, depends on the transversal size of holes, while the extension of the yield zone could be affected by the longitudinal size, shape, distance and number of holes. Then, in the experimental campaign these parameters have been chosen as ...

If the anatomy at the occipito-atlanto-axial region {O-C1-C2; O: occiput, C1: atlas, C2: axis} is normal on X-ray, the dislocation should be reducible. In case congenital anomalies at O-C1-C2 and IAAD are seen on flexion/extension studies of the cervical spine, the C1-C2 joints ...
