Answer 9

Fracture of the dens of C2 , often requires surgery to fix

Question 10

A spinal cord injury above C4 can cause damage to what important nerve/structure

Answer 10

Phoenician nerve, affecting the inner action of the diaphragm

Question 11

Clay shovelers fracture

Answer 11

Spinous process fractures in the cervical spine, generally considered stable

Question 12

Spinous process fractures are typically caused by

Answer 12

Blunt force trauma to the spinous process itself, sometimes hard to see on X-ray due to overlying musculature of the rib cage

Question 13

Perched facets injury

Answer 13

Transient dislocations may cause a perching of the facet joints and locking in place, preventing the recovery of normal alignment

Question 14

Compression injuries include:

Answer 14

Compression fractures
Burst fractures
Chance fractures
Generally result of insufficient bone strength (osteoporosis) or forced hyperflexion (trauma)
