Study Notes
Joint Types in the Vertebral Column
- Synovial joints are classified within the vertebral column, specifically at the zygapophyseal joints.
- Intervertebral joints are classified as cartilaginous joints, allowing limited movement between vertebrae.
Scottie Dog Appearance
- The Scottie dog appearance in lumbar radiographs refers to a specific imaging sign used to identify certain spinal conditions.
- Key components of the Scottie dog include the body, head, legs, and tail, visually resembling a dog.
Components of the Scottie Dog Projection
- The nose of the Scottie dog in radiographs is formed by the transverse process of the lumbar vertebra.
- One pedicle contributes to forming the eye of the Scottie dog, while the superior articular process forms the top of the head.
Anatomical Features
- The pars interarticularis is a crucial bony structure located between the superior and inferior articular processes of a lumbar vertebra, significant in identifying spondylolysis.
- The zygapophyseal joint in lumbar projection refers to the synovial joint formed by the articulation of the superior and inferior articular processes of adjacent vertebrae.
Miscellaneous
- Not all components, such as the facet joints or spinous processes, are considered part of the Scottie dog in lumbar radiographs.
