Rotation at each C-spine level
O-C joints | 2-5 degrees |
C1-C2 | 50% |
subaxial spine | 2-10 degrees/level |

Ligament | Image | Facts |
Apical | ㅤ | ㅤ |
Alar | ㅤ | - connect dens to clivus - injured in AOD (along tectorial membrane) |
Transverse (part of Cruciate ligament) | ㅤ | - allows neck rotation - inserts on medial tubercule of C1 lateral mass - rupture → C1 onto C2 translocation - holds odontoid aspect to posterior aspect of C1 anterior arch - if this is violated, need to do a C1-C2 fusion, no odontoid screw is not enough |
Spinal Tracts
Ascending Tracts (Sensory)
Tract | Functions | Notes |
Posterior Columns | fine touch, vibration, proprioception, stereognosis, deep pressure | CG (T6): Cuneus: C spine to T6, Gracilius: below T6 |
Anterior spinothalamic | crude light touch (non-discriminiative) | transmit to VPL |
Lateral spinothalamic | pain, temperature | transmit to VPL |
