Younger women with risk factors
Men with risk factors
Inflammatory vs Non inflammatory pain
Inflammatory - red and warm
Non-inflammatory - cool to touch, edema or swelling around joint without warmth
Lupus
Autoimmune disorder
Joint pain with butterfly rash on the face
Psoriatic arthritics
Autoimmune disorder
Joint pain with scaly rash on elbows and pitting nails
Lyme
Infection
Joint pain with “bullseye rash” - expanding erythematous patch
Mental status changes, facial weakness or stiff neck indicate CNS involvement.
Serum sickness
Joint pain with hives
Reiter’s syndrome
Genetic disorder
Joint pain with erosion or scaling on the penis and crusted scaling papules on the soles and palms.
Red, burning, itchy eyes.
Gonococci arthritis
Infectious process
Joint pain with papules, pustules or vesicles with red base on extremities.
May start with a sore throat.
Ulcerative Colitis and Sclerodermaa
Joint pain with diarrhea, abd pain and cramping
Types of Swelling
Synovial membrane may feel boggy
Effusion from excess synovial fluid in joint or swelling
Soft-tissue structures like bursae, tendons, tendon sheaths
Muscle Strength Rankings
0 = no contraction, complete paralysis
1= slight contraction but severe weakness, extremity doesn’t move
2 = Full passive ROM
3= Full ROM with gravity but not against resistance
4=Full ROM with gravity and with some resistance
5= Full ROM, normal finding
Examination of TMJ (inspection, palpation, ROM)
Inspection-Facial symmetry
TMJ swelling or redness
Palpation - Muscles of Mastication
ROM - Open and close, protrusion and retraction, side to side
3 landmarks of the shoulder
A - Acromian process
B - Coracoid process
C - Greater tubercle
ROM of shoulder
Flexion, extension, abduction, adduction internal rotation (hands behind small of back) and external rotation (hands behind neck)
Apley Test
Touch opposite scapula over shoulder and around the back. Difficulty suggests rotator cuff problem or adhesive capsuilitis
Neer’s Test
Press scapula and raise patient’s arm on same side.
Difficulty is a + and indicates rotator cuff inflammation or tear
Hawkin’s Test
Flex patient’s shoulder and elbow 90degrees palm down. Rotate arm internally. Pain is + for inflammation or tear of rotator cuff
6 Tests for Rotator Cuff Injury
Apley Test Neer's Test, Hawkin's Test "Empty Can" Test Forearm supination Drop arm test
Suprapinatus “Empty Can” Test
Elevate pt’s arms, point their thumbs down, apply pressure. Weakness is + and indicates rotator cuff tear
Forearm Supination test
Flex forearm to 90 degrees at elbow and pronate wrist. Provide pressure as patient tries to supinate. Pain is + for inflammation at head of biceps tendon or rotator cuff gear
Drop Arm Test
Abduct arm to shoulder level. Ask pt to lower slowly as you tap it. If arm just drops, + for rotator cuff tear
Aprehension Test
Externally rotate shoulder with elbow bent. + patient becomes apprehensive. Indicates dislocated shoulder
What are common/concerning symptoms?
Low back pain Neck pain Monoarticular/polyarticular joint pain Joint pain with systemic features Joint pain associated with symptoms from another organ system
Acute Rheumatic fever
Sore throat that precedes joint pain
What would crepitus sound like upon palpation?
Rice crispy sound over joints
What is rotator cuff tendinitis?
- Caused by overuse or injury
- common in young adults and middle aged athletes
- minor pain with activity and rest
- pain from front of shoulder to side of arm
- sudden pain with lifting/reaching movements
- tenderness below the acromion
What is a dislocated shoulder?
- shoulder instability from anterior dislocation of the humerus. Joint “slipped out”
- positive apprehension test
- pain from any shoulder movement
- rounded edge of lateral aspect of shoulder appears flattened
What is a rotator cuff tear?
- injury from fall or repeated impingement
- partial or complete tear, usually after 40yrs
- weakness, atrophy, pain and tenderness of supraspinatus and infraspinatus muscles
- positive drop arm test- will shrug to lift shoulder
What is adhesive capsulitis?
- frozen shoulder
- fibrosis of glenohumeral joint capsule, fibrosis builds up from overuse
- diffuse, dull, aching pain
- progressive restriction of activity/passive range of motion
- no localized tenderness (is diffuse)
- unilateral
- usually 50-70 years old
- antecedent painful disorder of the shoulder, that has decreased shoulder movement
What is acromioclavicular arthritis?
- From prior injury, results in a degenerative change in the joint
- common
- pain with abduction
- tenderness localized to the AC joint
ROM of elbow
Flex and extend elbow
Pronate and supinate hand
What is olecranon bursitis?
- swelling and inflammation of the olecranon bursa
- from trauma, rheumatoid arthritis, gouty arthritis
- If RA: warm, balloon filled w/ water
- If gout: will feel the crystals
- swelling is superficial to the olecranon process
- no pain/discomfort
What is arthritis?
- synovial inflammation or fluid felt b/w olecranon process and epicondyles
- boggy, soft, fluctuant swelling, tender
- Causes: rheumatoid, gout, osteoarthritis, trauma
- pain, stiffness, restricted movement
What are rheumatoid nodules?
- subcutaneous nodules along pressure points on exterior ulnar surface
- seen in rheumatoid arthritis and acute rheumatic fever patients
- firm, non-tender, fixed
- located more distally from the olecranon bursa
What is lateral epicondylitis?
- tennis elbow, common
- pain with extension of the elbow, esp. against resistance
- tender 1cm distal to the lateral epicondyle
- from repetitive extension of wrist or forearm pronation-supination
What is medial epicondylitis?
- pitcher/golfers elbow
- pain with flexion, esp. against resistance
- tender lateral and distal to medial epicondyle
- from repetitive wrist flexion, like throwing
ROM of wrist
flexion
extension
ulnar abduction
radial adduction
ROM of fingers
flexion
extension
abduction (fingers spread apart)
adduction (finger back together
ROM of thumb
