Spondylolysis
|
-Broken vertebra (usually involves a specific part of the vertebra and occurs in the lumbar region - L5)
-Trauma or degenerative disease -Common cause of spondylolisthesis |
|
|
Pars interarticularis
|
Located b/t inferior and superior articular facets, between the lamina and pedicles of vertebrae
-Fractures at this point associated with spondyloysis -Looks like a Scottie Dog on radiograph |
|
|
Spondylolisthesis
|
-Anterior/ventral displacement of one vertebra on adjacent
-Common progression from spondylolysis, can also be congenital |
|

|
Herniation usually occurs in what direction and why?
|
Posterolateral direction partly because the posterior longitudinal ligament is not very broad (unlike anterior longitudinal ligament)
|
|
|
What ligamentous strctures make up the intervertebral joints
|
Annulus fibrosis
Anterior longitudinal ligament Posterior longitudinal ligament |
|
|
Thorasic Outlet Syndrome
|
An extra rib(s) in lower cervical region causing impingement of the large vessels and nerve (brachial plexus) in the region
-Other causes: fracture clavicle, poor posture |
