FRAX (fracture risk assessment tool):
Medical history: history of fall, fracture
Drug history: glucocorticoid/thyroxine/cyclosporine/tacrolimus/anti-convulsants
Family history: family history of osteoporosis
Social history: smoking, alcoholism, physical inactivity, malnutrition
PE: height and weight measurement (vertebral fracture: kyphosis, height loss)
Signs of secondary causes of osteoporosis: Cushing syndrome, thyrotoxicosis
Factors influencing propensity to fall: vision/hearing/gait/postural sway/muscle strength

Classification
What are the RF of OA?
What are the pathological features of OA?

What is the complication of OA?
OA with calcium pyrophosphate deposition (CPPD)
General features
* May be present in as many as 30 – 60% of unselected OA patients
* OA with CPPD is not any more rapidly progressive than OA alone but some may develop
rapidly progressive destructive arthropathy
* Presence of CPPD may modify OA symptoms especially with longer early morning
stiffness and more signs of synovitis
What are the general features of RA?
Inflammatory + Symmetrical + Polyarthritis
* Destruction of joints due to erosion of bone and cartilage
* Stretching of tendons and ligaments
Progresses from periphery to more proximal joints and results in locomotor disability
Joint distribution
* Affects hands (PIP/ MCP/ IP of thumbs), wrists, feet (MTP) in the early stages
* Involve other synovial joints including shoulder, elbow, knees and ankles
What is the pathogenesis of RA?
What are the SS of RA?
What are the specific joints involvement in hand RA?
How are the wrist, elbow, shoulder
Lower extremities: feet, knees
Cervical spine
Others involved in RA
What are the systemic and non articular manifestation of RA?
What is the ddx for RA?
How to clinically assess RA?
What is the diagnostic criteria for RA?
Three ‘A’s and two ‘6’s
1. Arthritis
2. Antibodies (anti-CCP, RF)
3. Acute phase reactants (ESR, CRP)
- 6 weeks duation
<6 weeks duration: 0
>6 weeks duration: 1 - > 6/10 points = Definite RA
What are the Ix done for RA?
What is the medical treatment for RA?
Mnemonic: ELISA Please Give Her Methotrexate
E-Etanercept
L-Leflunomide
I-Infliximib
S-Sulfasalazine
A-Anakinra
P-Penicillamine
G-Glucocorticoid + Gold salts
H-Hydroxychloroquine
M-Methotrexate
What is the prognostic factors for RA?
What is the disease activity assessment of RA?
What is the response criteria for RA?
You are examining a pair of hands. Examination reveals there is ulnar deviation, swan neck deformity, Z- shaped thumb, wasting of hand muscles, rheumatoid nodule. The patient appears to be unable to unbutton clothes.
What is the most likely diagnosis?
What are your differential diagnosis?
What important clinical manifestation helps to make the above differential diagnosis less likely?
Most likely dx is Rheumatoid arthritis
ddx
Polyarticular gouty arthritis and elbow gout tophi ± Bursitis
Nodular osteoarthritis
Psoriatic arthritis
Jaccoud’s arthritis of SLE
More likely RA reasons
Presence of ulnar deviation, Z-thumb and swan neck deformities makes gout arthritis less likely
Absence of MCP and wrist involvement makes nodular osteoarthritis less like
Absence of associated skin psoriatic lesions and presence of subcutaneous nodules makes
psoriatic arthritis less likely
Presence of rheumatoid nodules makes Jaccoud’s arthritis of SLE less likely
What are the complications of long-standing rheumatoid arthritis?
Descirbe the types of drugs used to treat RA and their complications?
What are the RF for septic arthritis?
Which joint affected most?
Knee affected most

What are the general features of ankylosing spondylitis (part of 1/4 seronegative spondyloarthritis)?
What are the musculoskeletal manifestation of ankylosing spondylitis?
What are the extra-articular manifestations of ankylosing spondylitis?
Mnemonic for ankylosing spondylitis

What are the important extra-articular features to look for in assessing a patient with inflammatory back pain?
Evidence of skin psoriasis
* Located in scalp, behind ears, peri-umbilical, natal cleft, extensor aspects of elbows,
knees and trunk
Reiter’s syndrome
* Presents with urethritis and painless urethral discharge
Eye involvement
* Conjunctivitis and iritis
