Rotation of the Cervical Spine: A CT Study in Normal Subjects

PENNING, L, WILMINK, J T·1987·Spine

Abstract

A computed tomography (CT) study of rotation of the cervical spine was undertaken in normal subjects aged 20 to 26 years. Section scans through the neck were made with the head in maximal rotation to the right or the left. Occiput, cervical spine, and first thoracic vertebra, thus, were depicted in different degrees of rotation with respect to the sagittal plane. These differences indicated the maximal degree of rotation in each of the eight segments between occiput and thoracic spine. Mean values for these segments were 1.0 degree, 40.5 degrees, 3.0 degrees, 6.5 degrees, 6.8 degrees, 6.9 degrees, 5.4 degrees and 2.1 degrees, respectively. Measurement error proved to be relatively small. By means of CT sections in the plane of the intervertebral joints (in three subjects in midposition, in one subject in maximal rotation of the head to one side) an axis of rotation could be constructed from the anatomic shape of the uncovertebral joints. The theory of Hall that the unciform processes are essential for rotation is confirmed and further elaborated.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
