Test 2 Part 2 Flashcards
What condition is a variant of DJD, appears unusually inflammatory, gives a classic “gull wing” sign, and is easily confused with RA?
Erosive OA
Who is more likely to get Erosive OA?
middle-aged females
When looking at erosive OA on films, what are the 2 most acceptable differential diagnoses?
psoriatic arthritis and RA (central erosions proximally and peripheral distally)
What is the most common joint for DJD in the feet?
1st MTP joint (known as hallux rigidus)
commonly occurs with DJD of the 1st MTP
bunion
T/F: heel spurs are enthesopathic changes.
True
T/F: the Glenohumeral joint is commonly involved with degenerative changes with or without prior trauma.
False; this is true of the AC joint tho
What condition should you suspect if a person has DJD of the Glenohumeral Joint, but has no prior trauma?
CPPD (pseudogout)
What is a FOOSH injury?
Fall On Out- Stretched Hand
aka frozen shoulder
adhesive capsulitis aka shoulder impingement syndrome
What condition involves elevation of the humeral head, degenerative enthesopathic changes of the humeral head, spurring of the acromion process, and rotator cuff (supraspinatus) degeneration?
Shoulder Impingement Syndrome
What condition involves deposition of calcium within the tendons and bursa, occurs in the 40-70 age range, and most commonly in the supraspinatus tendon?
Hydroxyapatite Deposition Disease (HADD)
What condition is commonly seen about the shoulder, elbow, wrist, hip, knee, ankle, and/or spine, and is aka calcifying tendinitis/bursitis or aka peritendinitis calcarea?
HADD
T/F: The lateral compartment is most commonly affected by DJD before the medial compartment.
False; vice-versa
What are the terms for the 3 compartments of the knee (used when discussing DJD)?
medial tibiofemoral,
lateral tibiofemoral,
retropatellar
A person with Genu Varus will commonly have DJD of which knee compartment?
medial tibiofemoral
If a patient has DJD of the lateral knee compartment, would that produce genu valgus or genu valgum?
valgum
imagine a piece of gum holding the knees to each other
Which side of the tibia is the popliteal fossa?
lateral
What condition involves calcification of the medial tibial collateral ligament (HADD)?
Pelligrini - Steida Calcification
What are joint mice?
Intraarticular fragments (fragments of cartilage, meniscus, or synovium within the joint which often calcify)
What condition involves multiple intra-articular loose bodies, synovial tissue metaplasia that produces cartilaginous masses, is common in the knee, hip, ankle, shoulder, and wrist, may present with joint mice, and may ultimately ossify to become radiographically visible?
Synovial Osteochondrometaplasia (SOM)
What is the term for a slow growing, benign, and locally invasive tumor of the synovium, which most often involves the knee (also in hip, knee, and elbow), affects young to mid aged adults, and may resemble RA?
Pigmented Villonodular Synovitis (PVNS)
What condition involves intra-articular effusions, lobulated masses, bony erosions in “tight joints,” “apple core” deformity, and may appear “bubbly?”
Pigmented Villonodular Synovitis (PVNS)
What are Eggar’s cysts?
subchondral cysts/geodes
