  • Front
  • Back
avulsion fracture of the spinous process of any vertebra C6-T-1; may see
"double spinous process sign"
Clay shoveler's fracture
wedge-shaped vertebral body from lateral perspective; irregular spacing from AP perspective
Compression fracture
fracture of the anterior C2 arch, usually also with anterior subluxation of C2 on C3
Hangman's fracture
bilateral offset or spreading of the lateral masses of C1 relative to the dens
Jefferson fracture
fracture line through base of dens, possibly extending into lateral masses or arches of C1
Odontoid fracture
comminuted vertebral body fragments avulsed from the anterioinferior border and fragments from the posterior vertebral body displaced into the spinal canal.
Teardrop burst fracture
unilateral "bow tie" deformity b/c the vertebra is rotated on its axis; bilateral "jumped" deformity b/c the entire vertebra is located more anterior than it should be
Facets
possible narrowing in disk spacing b/w vertebrae and protrusion of disk into the spinal canal on CT or MRI
Herniated nucleus pulposus (HNP)
abnormal or exaggerated convex thoracic curvature
kyphosis
normal concave lumbar curvature or abnormal or exaggerated lumbar curvature
lordosis
Abnormal or exaggerated lateral curvature of spine
scoliosis
Degeneration of cartilage and formation of osteophytes (bony outgrowths)
Osteoarthritis
BMD(bone mineral density) loss
Osteoporosis
Mild kyphosis and/or scoliosis, most common involvement of thoracic spine
Scheuermann's disease
calcification w/ ossification, creating stiffness and lack of joint mobility.
spondylitis ankylosing spondylitis
this fracture results from hyperflexion of the neck and results in avulsion fractures on spinous process, best demo. on a lateral c-spine
Clay shoveler's fracture
often involves collapse of a vertebral body resulting from flexion or axial loading in thoracic or lumbar regions, best demo. on a lateral proj.
Compression fracture
occurs when the neck is subjected to extreme hyperextension, best demo. by a lateral c-spine
Hangmans's fracture
this comminuted fracture (splintered or crushed at site of impact) occurs b/c of axial loading, best demo. on an AP open mouth & lateral projections.
Jefferson fracture
joint classification & movement type of (skull C-1) Atlantooccipital
Synovial, Ellpsoid
joint classification & movement type of C1-C2 Rt & Lt lateral atlantoaxial (2)
Synovial, Plane
joint classification & movement type of C1-C2 medial atlantoaxial (1)
Trochoid, Pivot
joint classification & movement type of C2- T12 intervertebral
Cartilaginous, N/A
joint classification & movement type of zygapophyseal
synovial, plane
Joint classification and movement type of T1-T12 Costovertebral
Synovial, Plane
Joint classification and movement type of T1-T10 Costotransverse
Synovial, Plane
The spinal cord is enclosed and protected by the _______ & begins w/ the _____ ______
spinal canal, medulla oblongata of the brain
What are the 5 sections that the vertebral column is divided into
Cervical, Thoracic, & Lumbar vertebrae, Sacrum and Coccyx
What does concave and convex mean
concave-rounded inward

convex-rounded outward
