Question | Answer |
---|---|
Ossification center of Dens doesn't fuse with body of the Dens | Ossiculum Terminale Persistens |
So mites fail to segment resulting in fusion of vertebrae | Block Vertebrae |
Lack of union between Odontoid and body of C2 | Os Odontoideum |
Partial to complete lack of Odontoid Process | Hypoplastic and Agenetic Odontoid Process |
Short, webbed neck, low hairline, reduced ROM | Kippel-Feil Syndrome |
Failure of Scapula to descend | Sprengel's Deformity |
Cartilage or fiber band running from C5/6 SP to Superior Angle of Scapula | Omovertebral Bone |
Two nerve roots exit from one large Foramen | Absent Pedicle |
Results from a cleft in the posterior arch | Cervical Spondylolisthesis |
Developmental narrowing of spinal space due to elongated, flat vertebral bodies | Platyspondyly |
Costal process articulating with C7 | Cervical Rib |
Often leads to Dysphagia, feeling of fullness in throat, face pain | Stylohyoid Ligament Ossification |
Associated with a rudimentary form of congenital non-segmentation | Elongated Anterior Tubercle with Accessory Joint |
Saggital cleft in a vertebral body | Butterfly Vertebra |
Portion of vertebra does not ossify, triangular shaped segmentation | Hemivertebra |
Endplates of adjacent vertebra alter and conform to Hemivertebra | Incarcerated Hemivertebra |
Hemivertiebra is fused to the adjacent segment without an intervertebral disc | Non-segmented Hemivertebra |
Adjacent endplates are straight and will more likely cause Scoliosis | Non-incarcerated Hemivertebra |
Fibrous, cartilagenous, or bony bar divides the spinal cord or Cauda Equina and fixes it to the midline | Diastematomyelia |
Herniation of disc material into vertebral body | Schmorl's Nodes |
Persistent Notochord, Cupid's bow (look like Schmorl's Nodes) | Nuclear Impression |
Neural Arch does not ossify and pedicle is absent or semi-absent | Agenesis of Lumbar Pedicle |
Multiple levels of Schmorl's Nodes with anterior vertebral body wedging | Scheuermann's Disease |
Non-union between the two halves of the Post Arch | Spina Bifida Occulta |
Wide, bony defect in Post Arch with protrusion of spinal cord contents | Spina Bifida Vera |
Disc material herniation through Growth Center of the Ring Apophysis | Limbus Bone |
Vertebra with lumbar and sacral characteristics | Lumbosacral Transitional Vertebra |
Appearance of Lumbar vertebra on one side and Sacral base on the other | Unilateral Transitional Segment |
Assymetrical facets | Facet Tropism |
Lack of an Articular Process | Agenesis of Articular Process |
Secondary growth centers of the Articular process do not unite | Oppenheimer's Ossicle |
Combination of Spina Bifida Occulta of the S1 and elongated SP of L1 | Clasp Knife Syndrome |
Hahn's Cleft | |
Flattening of the Base of Skull | Platybasia |
Upper Cervicals in a superior position when related to the Skull | Basilar Impression |
Ow lying Cerebellar Tonsils, triangular shaped Cerebellar Tonsils, kinked 4th Ventricle | Arnold-Chiari Malformation |
Congenital Atlanto-occipital fusion | Occipitalization of the Atlas |
Inferior somite of the Occiput fails to unite and remains as an extra ossicle | Occipital Vertebra |
Bridge from Anterior Foramen Magnum to apex of the Odontoid Process/Ant Arch | Third Condyle |
Congenital, bony bar bridge C1 TP to the Occiput | Epitransverse Process |
Congenital, bony bar bridge originates medial and anterior to the Paramastoid Process And connects to atlas TP | Paracondylar Process |
Congenital, bony bar bridge originates from the Jugular Process of the Occiput to atlas TP | Paramastoid Process |
Bony ossicles in the Atlanto-occipital space | Atlanto-Occipital Ossicles |
Posterior arch cleft, unilateral agenesis, or complete agenesis of Post Arch | Agenesis of Posterior Arch of Atlas |
No midline ossification of Neural Arch of C1 | Posterior Spina Bifida Occulta of Atlas |
Vertical lucency over Odontoid Process on APOM View | Anterior Spina Bifida Occulta of Atlas |
Oblique ossification of Atlanto-occipital membrane | Pont Ponticle of Atlas |
