Fracture C1 | Jefferson or Burst Fracture |
Jefferson/Burst fracture | C1 ring; blow to top of head; diving; 1/3rd associated with fracture C2; can be associated with injury to transverse lig |
Transverse ligament | prevents posterior displacement of dens and anterior displacement of atlas |
rupture transverse ligament | destabilization injury; flexion injury; |
atlantoaxial subluxation | softening vs rupture of transverse ligament; more likely to cause spinal cord compression than fracture of dens |
atlantoaxial subluxation | seen in connective tissue disorders such as 20% ppl with Downs Syndrome |
Fracture of Dens of C2 | from horizontal blow to head or complication of osteopenia |
Hang Mans Fracture | hyperextention traumatic spondylosis(disc degeneration) C2 from hanging or whiplash |
Tear drop fracture | Flexion injury during MVA is most common; may involve anteroinferior or posterior inferior body fragment; often associated with spinal cord injury due to posterior fragment encroaching into canal and cause paralysis |
Clay Shovelers fracture | stable fracture |
Clay shovelers fracture | through spinous process of a vertebrae; usually lower cervical or upper thoracic but mostly C6/7; pain between shoulder blades |
Chance Fracture | most common is T12-L2 and midlumbar in Peds |
Chance Fracture | violent forward flexion injury; compression in anterior portion; 50% associated with intrabdominal injury |
Chance Fracture | seatbelt injury |
Holdsworth Fracture | unstable |
Holdsworth Fracture | dislocation of thoracolumbar junction; flexion/rotation injury with fracture through vertebral body, rupture posterior spinal ligaments, fracture of facet joints |
Most commonly fractured vertebrae | T12 due to transitional stresses |
Most commonly dislocated vertebrae | Cervical |
Most commonly disc degenration, herniation, arthritic spondylosis and spondylolisthesis | Lumbar |
Batson's venous plexus | gives a way for prostate cancer to metastasize to lumbar vertebrae; it drains each segmental level and is continuous with the pelvic veins; located in epidural space |
Spinal stenosis | hurts when walk/stand, better when sit |
Disc herniation | Better when walk, hurts when sit due to 7x increase in interdiscal pressure while sitting |
Spondylosis | characterized by disc degeneration and osteophytosis; see pars defect with a scottie dog collar sign |
Spondylolisthesis | slipped disc |
Unstable spondylolisthesis | more than 4mm change of translation with flexion/extension |
Uncovertebral joints | Joints of Luschka; C3-C6; frequent sites of spur formation |
Ligamentum flava | extend vertically from lamina above to lamina below; stop abrupt flexion of vertebral column, protecting IV discs from injury |
Extension | splenius capitus |
extension | multifidus |
extension | longissimus capitus |
extension | semispinalis capitus |
extension | trapezius |
rotation | rotatores |
rotation | splenius cervicus |
rotation | semispinalis capitus |
rotation | semispinalis cervicus |
segmental arteries | trunk |
subcostal and lumbar arteries | abdomen |
segmental arteries | supply vertebral bodies |
segmental medullary arteries | supply spinal nerve roots and spinal cord |
lumbar puncture | extraction of CSF from lumbar cistern |
Lumbar puncture | needle inserted between L3/4 |
spinal block | anesthetic into CSF |
epidural block | anesthetic into epidural splace |
epidural block | used in childbirth |
Longitudinal arteries | supply spinal cord; 1 anterior spinal artery and paired posterior spinal arteries |
Veins of spinal cord | 3 anterior and 3 posterior spinal veins |
injury C1-3 | no function below head; requires ventilation |
injury C4-5 | quadriplegic with resp function |
injury C6-8 | some UE motion |
injury T1-9 | paraplegic |
erector spinae muscles | Iliocostalis, longissimus, spinalis |
