AS involves axial skeleton
but peripheral joints including TMJ and arytenoid cartilages may also be affected making tracheal intubation impossible1.
BMD was measured from the appendicular skeleton like femoral neck, and also in Ward's triangle, and for axial skeleton
from L1 - 5 lumbar spines.
Metastasis frequently involves red marrow which is more abundant in axial skeleton
such as spine.
First, despite the fragmentary nature of both holotypes there are a considerable number of differential characters within the overlapping material (mainly in the axial skeleton
Ankylosing spondylitis (AS) is a chronic inflammatory disease affecting sacroiliac joints and axial skeleton
1] It commonly spreads to regional lymph nodes via lymphatic vessels, direct invasion to pelvic organs or systemically to the axial skeleton
The human skeleton is composed of 206 bones and is divided into the axial skeleton
that includes the skull, hyoid, sternum, ribs and vertebrae and the peripheral skeleton that includes the bones of the limps and the pelvis.
2) Sclerotic bone lesions in tuberous sclerosis are frequently seen in the axial skeleton
especially calvarias and spine, are at times distributed focally and have irregular borders and variable size.
The sacroiliac (SI) joint is actually a pair of special joints located between the lumbar sacral spine and the hip joints, which are critical in weight transfer from the axial skeleton
to the lower limbs.
Based on site of origin, eighty two percent of these tumors involved appendicular portion of skeleton and 18% involved axial skeleton
1%, respectively), and appendicular fracture detection was superior to that of the axial skeleton
Multiple "punched out" lesions in the calvarium and axial skeleton
are a classic appearance of this disease (Figure 6).
In this pictorial essay, we focus on the characteristic axial skeleton
imaging findings of AS, as it presents on conventional X-ray: (1)
They tend to affect the axial skeleton
and are associated with abdomino-pelvic disease.
Composed of appendicular and axial skeleton
bones, the pelvis is a transitional body part between the lower extremities and the spine.
