Where does OA affect
DIPS
PIPS
1st CMJs
Scaphoid, trapezium, trapezoid
RA arthritis joint involvement
DIPS SPARED
MCPs, PIPs, thumbs, ulnar styloid
Why might we do USS or contrast MRI
Synovitis can show up before bone changes take place
Ankylosing spondylitis -
Disease has set in, fusion between bones, esp axial skeleton
Ank spond is a type of which group of diseases? Name the four
Seronegative B27 axial spondyloarthropathies:
Ank spond
Psoriatic
Reactive
Enteropathic
What do you see in axial spondylitis on x ray
Fusion across sacroiliach joint
Fusion across vertebral bodies
Desmophytes
Bamboo spine
Midline calcificaiton - dagger sign
MRI can show things up in Axial spondyloarthropathies, what can it show up before x rays?
BM oedema
How do you describe an x ray of a fracture? List.
Projection and side - AL and lateral radiograph of left hand and wrist
Location - fracture of distal radius and distal ulnar bone
Intra/extra articular - intraarticular extension
Displacement -
Direction of displacement
- palmar/volar or dorsal
- medial/lateral or radial/ulnar
- impacted (where the two ends of the bone are touching each other )/distracted means they are apart and there’s a gap
Angulation - relative to the DISTAL fracture fragment - where is it facing?
Dislocation/subluxation
Comminuted or simple (how many fractures)
Open or closed
what is a chalk stick fracture
ank spond of neck - when it gets broken into two
Classification systems
denis 3 column classification for spinal stability
2 or more = unstable
SC Compression causes
Trauma
Sepsis
Metastatic
Herniated disc
