IM Arthropathies Flashcards
Non articular/ Articular:
Deep/diffuse pain or limited ROM during passive and active movement
• Swelling, crepitation, instability, deformity
• Examples: see algorithms
Articular
Non articular/ Articular:
Painful on active (but not passive) ROM
• Seldom with swelling, crepitus, instability
• Examples: trauma/fracture, fibromyalgia,
polymyalgia rheumatica, bursitis, tendinitis
Non articular
Commonly affected joints: Cervical and lumbosacral spine, Hip,
Knee, first MTP joint, hand joints (DIP, PIP)
OA
Joint space loss or narrowing is a typical radiographic finding
OA
Manifests as DIP and PIP pain with bony hypertrophy sufficient to produce Heberden’s and Bouchard’s nodes; pain +/-swelling involving base of thumb (1st carpometacarpal joint)
OA
Cause symmetric, polyarticular involvement of PIP, MCP, intercarpal, and carpometacarpal joints (wrist) with pain
RA
Single most accurate test for RA
Anti CCP Ab
- Flexor tenosynovitis (frequent hallmark)
- “Swan-neck deformity”
- “Boutonniere deformity”
- “Z-line deformity
RA
- Ulnar deviation from subluxation of the MCP joints
- Ulnar deviation from subluxation of the MCP joints
- Piano-keymovementofulnarstyloid
RA
Pathologic hallmarks of RA
oSynovial inflammation
oFocal bone erosions
oThinning of articular cartilage
RA
RA: most common pulmonary manifestation.
Pleuritis
Most common Valvulopathy in RA
Mitral Regurgitation
Nodular RA
Splenomegaly
Neutropenia.
Felty’s syndrome
Initial radiographic Finding in RA
Periarticular osteopenia
Male, sudden, knee & big toe, comorbids, presence of inflammation
Gout
Needle shaped monosodium urate crystals
negative birefringence
