Thoracic Spine Flashcards
What condition is demonstrated here?
Spondylosis
What condition is demonstrated here?
Costotransverse arthrosis
What condition is demonstrated here?
Costovertebral arthrosis
General & Radiographic features of ____ include:
- Autoimmune disorder that attacks muscle and skin
- Early see soft tissue inflammation (Increased soft tissue thickness & density, blurring of fascial planes)
- Sheet like soft tissue calcification as the disease progresses
- Joints show periarticular osteopenia, swelling
Dermatomyositis (Polymyositis)
What condition is demonstrated here?
Dermatomyositis
What condition is demonstrated here?
DISH (Diffuse Idiopathic Skeletal Hyperostosis)
What condition is demonstrated here?
Ankylosing Spndylitis
What is the 3 column concept for thoracic/lumbar spine trauma?
- If two or more columns are disrupted, then it is considered an unstable injury
- If the middle column is disrupted it is considered aunstable injury
(Anterior Column = ALL, anterior 2/3rds of vertebral body and disc
Middle Column = PLL posterior 1/3rd of vertebral body and disc
Posterior Column = Posterior arch, all other posterior ligaments)
General & Radiographic features of ____ include:
- Anterior loss of body height
- T12/L1 most common
- Wedge-shaped body
Compression fracture
What condition is demonstrated here?
Compression fx
What condition is demonstrated here?
What condition is demonstrated here in this 75 y.o. female?
Osteoporotic compression deformities
General & radiographic features of ____ include:
- Always involves anterior & middle columns
- One or both endplates involved
- Body enlarged in the axial plane
- Widened interpedicular distance
- Paraspinal line displaced
Burst fracture
What condition is demonstrated here?
Radiographic features of ___ include:
- Linear lucency (mimicked by lung markings)
- Cortical offset (best indicator)
- Extra pleural sign (from hemorrhage)
- Callus formation
Rib fx
What pathology is shown here?
Tuberculous Spondylitis
What pathology is shown here?
Tuberculous Spndylitis
General & Radiographic features of ____ include:
- Ribs MC affected
- Radiolucent, expansile, soap bubbly, rim of sclerosis
- May demonstrate ground glass matrix
Fibrous dysplasia
What pathology is shown here?
Monostotic Fibrous Dysplasia
What pathology is shown here?
Polystotic Fibrous Dysplasia
Radiographic features of ____ include:
- Osteopenia
- Pathological compression fractures
- Pedicles usually spared until late in the disease (referred to as the pedicle sign)
- Can cause punched out lesions in the ribs with no surrounding sclerosis or periosteal reactions
Multiple Myeloma
What pathology is shown here?
Multiple Myeloma
What pathology is shown here?
Multiple Myeloma
Radiographic findings of ___ include:
- Osteopenia
- Loss of secondary stress trabeculae results in an acceuntated appearence to primary stress trabeculae (vertical straitions in vertebral bodies)
- Pencil thin cortices
- Compression fractures
- Increased kyphosis
Osteoporosis
What pathology is shown here?
Osteoporosis
What pathology is shown here?
Osteoporosis
General & radiographic features of___ include:
- AKA Juveniles kyphosis
- Affects endplates, typically in the thoracic spine
- Multiple Schmorl’s nodes
- Endplate irregularities
- Anterior wedging of the vertebral bodies and discs
- Increased AP dimension of vertebra around apex of kyphosis
- Diagnostic Criteria: Anterior wedging of at least 5 degrees or more at three contiguous levels resulting in hyperkyphosis
