T4 Thoracic Spine Flashcards
What is the most common disease affecting the thoracic spine?
Osteoporosis
The upper thoracic spine refers to ____
The lower thoracic spine refers to ____
-T1-T2
- T3 - T12
T1 (cervicothoracic junction) and T12 (thoracolumbar junction) are considered…
Transitional vertebrae, therefore they can begin to move in unison w/ their articulating vertebrae
The ribs contribute to…
Spinal stability, restricting forward bending, side bending, and rotation, protect viscera
Which are the atypical ribs and what does this mean?
Ribs 1,11 & 12
This means they articulate with one vertebral body are not united to a disc and articulate with the numerically corresponding vertebral body only
Define typical ribs
Typical ribs, articulate with two vertebral bodies to the numerically corresponding vertebral body and the IVD and the vertebral body above. They have a head with two facets on either side of a tiny crest.
Ribs 11 & 12 are…
Floating ribs
Ribs 1 & 2 articulate with the ___
Ribs 3-7 articulate with the ___
- manubrium
- sternum
When the mid thoracic spine (T3 - T9)
Flexes the ribs roll…
Extends …
Laterally flexes…
Rotates…
- flexion: the ribs roll anteriorly and glide superiorly
-Extension: the ribs roll posterior and glide inferiorly - Lateral flexion: the ribs approximate ipsilaterally and separate contralateral
- rotation: the ipsilateral rib will posteriorly rotate. The contralateral rib will anteriorly rotate.
