Cervical Spine Flashcards
How many vertebrae in cervical spine?
7
C1-C7
note: 33 vertebrae in complete spine
what joint of the C-spine is important in the “sniff position”
atlanto occipital
What are C1 and C2 vertebrae also known as?
C1 = Atlas (think of the letter “l” in atlas as a 1 - “At1as”)
C2 = Axis
Identify the numbered structures of the cervicle vertebra
- body
- transverse process
- pedicle
- superior articular process
- lamina
- spinous process
- posterior turbicle of transverse process
- foramen transversarium
- anterior turbicle of transverse process
- sulcus (groove) for nerve
Note: the inferior articular process would located directly under # 4 if you were looking at lateral view of the vertebra
Identify the numbered structures
- occiput bone
- posterior atlanto-occipital membrane
- Atlas, posterior arch
- posterior atlantoaxial membrane
- Axis, arch
- posterior longitudinal ligament
- transverse ligament
- dens of axis
- Axis, anterior arch
- atlantoaxial ligament
What are the cervical landmarks associated with the larynx
C3 - hyoid bone
C4-C5 - thyroid cartilage (vocal cords at this level as well)
C6 - cricoid cartilage
Identify numbered structures
- foramen magnum
- occipital condyle
Labeled structures of atlas
labeled structures of inferior view of atlas
labeled structures of axis
what are the high risk managment of areas of the C-spine
C1 and C2
what part of the axis is subject to fracture
the dens (a.k.a.) odontoid process
what is the McGregor’s line?
drawn from posterior tip of hard palate to lowest point of occipital bone
avg normal position - odontoid tip 1.32 mm above line
Position > 4.5 mm above line is indicative of basilar impression
what % of movement of associated base of scull and c-spine
50% of flexion and extension
50% rotation
