after reviewing the initial images the ER doctor suspects either a congenital defect of fracture of the articular pillars of C4. Such great variance existed in measurements from spine to spine and within the same spine as to render averages clinically unreliable. a patient enters the ER with a possible cervical spine fracture but the initial projections don not demonstrate any gross fracture or subluxation. The average distances and ranges were recorded. The upper surface of the body is curved, somewhat in the shape of a saddle. The first 2, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively. Under My Thumb Rule always stand to the side of the articular pillar your being. Here’s a typical cervical vertebra, the fourth one. The cervical spine is made up of 7 vertebrae. The transverse processes arise from the side of the body, and also from here on the articular pillar.
to the dorsolateral aspects of the body by two stout pillars, the pedicles. The mass of bone between the articular facets is called the articular pillar. Landmarks were the lateral facet line, rostrocaudal line, medial facet line, intrafacet line, and medial facet line-vertebral artery line. (5.01) Now that we’ve looked at one vertebra, let’s look at the specialized and different features of vertebrae from the cervical, thoracic, and lumbar parts of the spine. Seven cervical, 12 thoracic, and five lumbar vertebrae compose the movable.
It is an unstable cervical spine fracture that results from hyperflexion. A floating pillar, also referred as pedicolaminar fracture-separation injury, is characterized by fractures through the pedicle and lamina of a cervical spine vertebrae creating a free-floating articular pillar fragment. Measurements of anatomical landmarks in 10 spines from human cadavers aged 61 to 85 years were made by caliper and a metric ruler. Citation, DOI, disclosures and article data. This paper defines key bony landmarks and their relationship to critical neurovascular structures and identifies a location for safe placement of cervical articular pillar (lateral mass) screws. superior and inferior articular processes of consecutive lumbar vertebra. Knowledge of the relevant anatomy is important when developing a strategy for introducing screws into the lateral masses to secure internal fixation devices.
