Ankylosing spondylitis
Ankylosing spondylitis (less commonly known as Bechterew disease or Marie-Strümpell disease) is a seronegative spondyloarthropathy, which results in fusion (ankylosis) of the spine and sacroiliac (SI) joints, although involvement is also seen in large and small joints.
Epidemiology

Central cord syndrome
Central cord syndrome is the most common type of incomplete spinal cord syndrome, usually, the result of trauma, accounting for ~10% of all spinal cord injuries. As the name implies, this syndrome is the result of damage to the central portion spinal cord and in the setting of trauma most common...
Article
Sacroiliac joint (AP sacrum view)
The AP sacrum projection is part of the sacroiliac series that includes an oblique projection (PA/AP) of the joint on both sides. Although usually taken as an AP projection it can also be taken PA with a reverse caudal central ray angulation of 30° to 35° when patients cannot assume supine posit...

Thoracic spine (lateral view)
The thoracic spine lateral view images the thoracic spine, which consists of twelve vertebrae.
Indications
This projection is utilized in many imaging contexts including trauma, postoperatively, and for chronic conditions. It can help to visualize any compression fractures, subluxation or kyph...
Article
Axis (C2)
The axis is the second cervical vertebra, commonly called C2. It is an atypical cervical vertebra with unique features and important relations that make it easily recognisable. Its most prominent feature is the odontoid process (also know as the dens or peg), which is embryologically the body of...

Article
Cervical spine (odontoid view)
The odontoid or 'peg' projection, also known as the open mouth AP projection (or radiograph), is an AP projection of C1 (atlas) and C2 (axis) with the patient's mouth open.
Indications
This view focuses primarily on the odontoid process of C2, and is useful in visualizing odontoid and Jefferso...
