    Typical T-Spine Vertebrae
  2. T1-T4
    More like C-Spine (smaller)
  3. T9-T12
    More like L-Spine (larger)
  4. Facets
    • 1. Only on T-Spine
    • 2. Articulations with ribs
  5. Costovertebral Joints
    Characteristics
    • 1. Each T-vert has either full or demifacet
    • 2. On each side of Vertebral body
    • 3. Head of rib meets facets
  6. Demifacets
    • 1. One on inferior and superior edge of v-body
    • 2. Rib head straddles between to v-bodies
  7. T1
    • 1. Full facet for rib 1
    • 2. Demifacet on inferior border
  8. T2-T8
    Demifacets on upper and lower borders
  9. T9
    Demifacet on upper border only
  10. T11-T12
    Full facets
  11. Costotransverse Joint
    • 1. 1st 10 T-vert have facets
    • 2. One on each transverse process
    • 3. Articulate with tubercles of ribs
  12. Costotransverse Joint
    T11-T12
    • 1. No facets on processes
    • 2. Only articulate at CostoV-joints
  13. Costotransverse Joint
    1st 10 Pairs Ribs
    • 1. Arch posteriorly
    • 2. Articulate w/ costo T-joint
  14. Costovertebral and Costotransverse Joints
    • 1. Articulations closely spaced and enclosed in synovial capsules
    • 2. Joints = synovial, diarthroidal, and plane (slight gliding)
  15. Thorasic Spine
    Characteristics
    • 1. Processes so long = best viewed in Lateral
    • 2. Spinous from above seen on body of below
  16. Thorasic Spine
    Zygapophyseal Joints
    • 1. 70-75* off MSP = 70-75* Obliques to open
    • 2. Synovial, Diarthroidal, Plane (gliding)
  17. Thorasic Spine
    IV Foramina
    90* off MSP = Lateral to open
  18. C2-T12
    Joint Characteristics
    IV = Cartilaginous, Amphiarthroidal, N/A
  19. Skull-C1
    Joint Characteristics
    Atlantooccipital Joint
    Synovial, Diarthroidal, Ellipsoid (condyloid)
  20. C1-C2
    Joint Characteristics
    R&L Lateral Atlantoaxial
    Synovial, Diarthroidal, Trochoid (pivot)
  21. AP Projection
    Best for...
    • 1. Vertebral body
    • 2. Can see posterior rib articulations
  22. Nuclear Med Scans
    Demonstrates
    • 1. Bone tumors
    • 2. Healing fractures
    • 3. Metastases of cancer
    • 4. Osteomyelitis
    • 5. Paget's disease
  23. Compreion Fractures
    • 1. Involves collapse of V-body from flexion or axial loading
    • 2. Most often in T&L-Spine
    • 3. Anterior edge collapses, changes shape of V-Body into wedge vs block
    • 4. Best viewed on Lateral
