Types of Vertebral Fractures
Compression fractures
Vertebral bodycollapses
Caused byosteoporosis, trauma, or tumor
Usuallyoccur at C7 and T1
Moderate to severe pain, limitation of movement, kyphosis
Jefferson fracture
Four part fracture of the ring of C1
Caused bya fall on the vertex
Patients have upper neck pain but can be neurologicallyintact
Hangman fracture
Caused byhyperextension of the head on the neck
Bipedicle fracture of C2
Anterior displacement of C2 and C3
Results in quadriplegia or death
Cervical Hyperextension
Most common in young adults from trauma and sports injuries and the elderly, resulting in cord compression
Result of whiplash from car accidents
Results in soft tissue injury, fractures, dislocations, ligamentous tears, and disc disruption
Clinical Points
Spinal curvatures:The primarycurvatures of the vertebral column in the thoracic and sacral regions develop during the fetal period and are caused bydifferences in height between the anterior and posterior aspects of the vertebrae. The secondarycurvatures are mainlya result of anterior-posterior differences in IVdisc thickness. The cervical curvature is acquired when the infant begins to lift its head, and the lumbar curvature when the infant begins to walk.
Abnormal curvatures:Kyphosis is an increased thoracic curvature, commonlyseen in the elderly("Dowager hump"). It is usuallycaused by osteoporosis, resulting in anterior vertebral erosion or a compression fracture.An excessive lumbar curvature is termed a lordosis and is seen in association with weak trunk muscles, pregnancy, and obesity. Scoliosis is an abnormal lateral curvature of the spine, accompanied byrotation of the vertebrae.
Spondylolisthesis:The lumbosacral angle is created between the long axes of the lumbar vertebrae and the sacrum. It is primarilybecause of the anterior thickness of the L5 body.As the line of bodyweight passes anterior to the SI joints, anterior displacement of L5 over S1 may occur (spondylolisthesis), applying pressure to the spinal nerves of the cauda equina.
Sacralization:In about 5% of individuals, the L5 vertebra is partiallyor totallyfused with the sacrum. Because the L5/S1 level is now very strong, the L4/5 level is likelyto degenerate in these cases.

Memory Aids
Vertebral bodies:
Thoracic are heart-shaped since your heart is in your thorax
Lumbar are kidney-bean shaped as the kidneys are in the lumbar area
Craniovertebral joints:
Atlantooccipital joint is the yes-yes joint because it permits nodding
Atlantoaxial joint is the no-no joint because it permits turning the head from side to side
