Q

Define: Osteophytes

A

Osseous proliferation at the articular margin (at the junction of the articular cartilage and the periosteum) - indicator of joint disease

Q

Define: Enthesophyte

A

Osseous proliferation at the insertion of ligaments/tendons/joint capsule on the bone - usually grow in the direction of the pull of the soft tissue structure

Q

Define: Intracapsular Swelling

A

Associated with the joint
Effusion, synovitis, synovial hypertrophy

Q

Define: Extracapsular Swelling

A

Outside the joint
Cellulitis, edema, hemorrhage, abscess

Q

What classifies a periosteal/endosteal lesion as aggressive?

A

Cortical destruction, active periosteal reaction, or indistinct transition zone
Only need one to be classified as aggressive

Q

Classify the fracture types
