Cervical Spine Flashcards
Ligamentous Stability
- Transverse
- Alar
Transverse Ligament
- Strong, primary stabilizer of upper cervical spine
- Prevents anterior displacement of C1 (atlas) over C2 (axis
Atlanto-Odontoid Interval Distance
Distance between Odontoid and posterior boarder of anterior arch of atlas
- < 3mm (adults)
- < 5mm (children)
Atlanto-Odontoid Instability Pathophysiology
Adult: Degenerative, RA, Type 1 Odontoid, Fracture (rare), Atlas Fracture, Transverse Ligament injuries
Pediatrics: JRA, Down syndrome
Alar Ligament Purpose
- Limits C0-C2 extension
- Limits: Rotation, Flexion, lateral flexion
- Stabilizing C1-C1 during rotation (Big Role)
Atlanto-Occipital Joint Osteokinematics
- Flexion: 15 deg
- Lateral Flexion: 2-11 deg
- Rotation: 0-7 deg
Atlanto-Axial Joint Osteokinematics (C1-C2)
- Flexion-Extension: 10 deg
- Rotation: 40 deg
Upper Cervical Spine (C0-C2) Osteokinematics
- C0-C1: Sagittal plane
- C1-C2: Transverse plane
- Together: 1/3 sagittal plane, 1/2 transverse plane
Lower Cervical Spine (C3-C7) Osteokinematics
- Flexion: 50 deg
- Extension: 60 deg
- Lateral Flexion: 45 deg
- Rotation: 80 deg
Coupled Motion of C3-C7
Lateral Flexion and Rotation coupled to the same side.
