Joint Disease Flashcards
What are the 5 things that make up the checklist for evaluating joint disease?
- Joint Space
- Subchondral Bone
- Margins of joint
- Surrounding Soft Tissue
- Miscellaneous
What is this showing?
What is this showing & what condition it associated with?
Ankylosis of intercarpal joints
Uniform loss of radiocarpal joint
(Associated w/ inflammatory arthritis)
What two conditions are demonstrated here?
Deformities can be seen in what kind of joint disease?
Degenerative, Inflammatory or Deposition
What is shown here?
Calcification of fibrocartilage (normally shouldnt be able to see meniscus)
What is shown here?
Calcification of hyaline cartilage
What is shown here?
Calcification of Intra-Articular Loose Bodies (not associated with any particular type of joint disease)
Fibrocartilage or Hyaline Cartilage calcification are associated with what category of joint disease?
Deposition
What is shown here?
Joint effusion (increased fluid) - Abnormal fat pads
Anterior sail sign, Posterior fat pad
What is shown here?
Joint Effusion in knee
What is shown here?
Joint Effusion ankle joint
What is shown here?
Abnormal Air in the joint (disc)
Also osteophytes and thickened end plates
Associated with Degenerative joint disease
What is shown here?
Normal gas in joint
Increased density of subchondral bone =
Subchondral sclerosis; referred to as endplate sclerosis in the spine
Decreased density of subchondral bone =
Periarticular osteopenia (aka juxta-articular osteopenia); referred to as endplate destruction in the spine
What is shown here?
Subchondral sclerosis (non-uniform with non-uniform loss of joint space)
Sclerotic changes (adding bone) is associated with what category of joint disease?
Degenerative
Taking away bone (osteopenia) is associated with what category of bone disease?
Inflammatory
What is shown here?
Endplate sclerosis
What is shown here?
Endplate sclerosis
What is shown here?
Periarticular osteopenia
What is shown here?
Endplate destruction (periarticular osteopenia in the spine)
What is shown here?
Subchondral cysts
Subchondral cysts are associated with category of joint disease?
Any of them (degenerative, inflammatory, deposition)
What is shown here?
Ill-defined Marginal Erosions
(Also subchondral cysts and loss of joint space)
Ill-defined marginal erosions are associated with what category of joint disease?
Inflammatory
What is shown here?
Well-defined Marginal Erosions
What is shown here?
Romanus lesions (marginal erosions in the spine)
What is shown here?
Central joint erosions
What is shown here?
Osteophytes (traction)
What is shown here?
Osteophytes (claw)
Syndesmophytes are associated with what joint disease category?
Inflammatory
What is shown here?
Marginal Syndesmophytes
What is shown here?
Non-Marginal Syndesmophyte
What is shown here?
Non-Marginal Syndesmophyte
What is category of joint disease would the following condition fall under?
Degenerative
Increased soft tissue size/thickness is most often seen in what joint disease category?
Inflammatory (also can be deposition like gout if mass instead of swelling)
What is shown here and what joint disease category is it generally associated with?
Generalized increase in soft tissue size/thickness
Inflammatory
What is shown here?
Calcification in soft tissue (supraspinatus tendon)
(Deposition in this case)
What category of joint disease would this be associated with?
Inflammatory
This case appears to have a _____ distribution
Associated with what type of joint disease category?
Unilateral
Degenerative
This case appears to have ____ distribution
Associated with what type of joint disease category?
Bilateral Asymmetric
This case appears to have ____ distribution
Associated with what type of joint disease category?
Bilateral Symmetric
Inflammatory
What is shown here?
Enthesophytes
What is shown here?
Enthesitis
What is shown here?
Non-articular bony erosions
Likely depositional disease such as gout
What is shown here?
Periostitis of adjacent bone (Associated w/ inflammatory/arthritic changes)
Decreased or increased joint space (typically non-uniforrm)
Osteophytes
Subchondral sclerosis & cysts
Enthesophytes
Unilateral/asymmetric
Joint effusion
These are characteristics of what joint disease category?
Degenerative
Uniform loss of joint space is associated with what joint disease category?
Inflammatory
What joint disease category is this associated with?
Deposition
What conditions are associated with deposition category?
Gout
CPDD (calcium pyrophasphate dehydrate deposition)
HADD (hydroxyapatite deposition disease)
Ochronosis
