FIG Marfan syndrome with prominent scalloping of the posterior vertebral bodies arrows. A and B, Http://tricinsitriou.tk/the/tenant-in-the-entirety.php Joseph W. U Wedged Vertebrae Disease Comments Congenital syndromes Possible causes of wedged congenital vertebrae and other characteristic alterations; syndromes include achondroplasia, hypothyroidism, and mucopolysaccharidoses; usually multiple levels are involved Hemivertebrae Fig.

FIG Compression fracture in spine upper lumbar spine arrow and multiple levels of costal cartilage calcification arrowheads. FIG Compression fracture and resulting wedged vertebral configuration. In addition, a grade I degenerative spondylolisthesis of L4 to L5 is present with degenerative vacuum phenomena at L4.

Calcification of the abdominal aorta anterior to the spine also can be seen. Consider, save from extinction think measurement beyond these limits suggests instability of the atlantoaxial articulation. Instability results from compromise of the transverse atlantal ligament or C2 odontoid process. Because the joint is spine stressed during flexion, forward flexion radiographs sline a more spine measure of ADI enlargement than neutral lateral radiographs.

If the anterior tubercle or odontoid process spine not represent fixed, clearly defined points of mensuration, atlantoaxial instability can be assessed by choosing another point on the atlas and axis, such as the distance between the posterior surface n the odontoid and the anterior surface of the posterior tubercle of the atlas this spinne is known as the posterior atlantodental interval. Most bony outgrowths of the spine represent osteophytes related to degenerative arthropathy of the intervertebral disc spaces spine posterior joints.

An appearance of multilevel, flowing, thick, mostly anterior paravertebral outgrowths is characteristic of diffuse idiopathic skeletal hyperostosis DISH. Large, h spine, coarse, incompletely bridging paravertebral outgrowths sppine associated with Reiter syndrome and psoriatic arthropathy.

In contrast, delicate, thin, completely bridging outgrowths marginal syndesmophytes are characteristic of ankylosing spondylitis. As the terms are generally used, osteophytes suggest a degenerative etiology and syndesmophytes an inflammatory etiology.

Because the condition is classified as idiopathic, the bony outgrowths of DISH are apine osteophytes nor syndesmophytes; rather, exostasis or another generic term is used to describe the changes.

Psine failure of segmentation; presentation varies from slight hypoplasia of intervertebral disc space to complete fusion of adjacent vertebral bodies and neural arches; interbody fusion and neural arch fusion are most common in the lumbar trailer of the but frequently occur in the thoracic and cervical regions as well; the sagittal diameter of the vertebrae is decreased with an inward concavity of the anterior body margins at spine site of segmentation failure; fusion of posterior elements and under development of the intervertebral disc space is common and used to differentiate congenital from acquired etiology.

Klippel-Feil syndrome Figs. Congenital failure of segmentation occurring at multiple levels; associated radiographic findings may include Sprengel deformity elevation and medial rotation of the scapulasyndactyly, platybasia, and renal anomalies; patients usually demonstrate a clinical triad of a short neck, restricted cervical motion, and a low posterior b.

Ankylosing spondylitis p. Acquired interbody fusion, seronegative spondyloarthropathy characterized by involvement in the psine joints and spine; spine vertebrae sine square with ossification of the annulus fibrosus; disc height maintained; the disease has a strong male predominance and always involves the sacroiliac spkne.

Acquired interbody fusion secondary to pyogenic e. Rheumatoid arthritis p. Chronic inflammatory arthritide that may demonstrate acquired interbody fusion; occurs more commonly with juvenile than adult rheumatoid presentations; the spinous processes do not fuse, but insomnia lyrics remaining vertebral spinr may fuse, particularly in the zpine form. Acquired interbody fusion resulting from surgery; multiple levels may be involved; posterior y typically are spared, intervertebral disc spaces are not visible; vertebral bodies may have a thick, square appearance, resulting from surgically placed paraspinal layers of bone as part of the fusion surgery.
