Dominant hand
Occupation Hx
Recreational interests/hobbies
Previous injuries-neck or upper extremity trauma

Question 22

Hand Inspection

Answer 22

Inspect/compare both sides when possible; note swelling or obvious signs of trauma; look for any muscle atrophy; look for joint deformity, Herberden’s nodes (OA); scars; nicotine staining; moles/skin cancer; hair nails-distribution and consistency of hair, consistency of nails and pitting, clubbing of fingertips

Question 23

Hand Palpation

Answer 23

Skin temp; radial and ulnar pulses; Allen’s test; palpate each joint for swelling and tenderness; palpate the skin of the palm for fascial thickening

Except the thumb, each digit has one extensor tendon | Extensor Digitorum Communis (EDC) 2-5

Question 26

Tendon exam of the hand: Flexor Mechanism

Answer 26

Except the thumb, each digit has two flexor tendons Flexor Digitorum Superficialis (FDS) flexes the PIP joint Flexor Digitorum Profundus (FDP) flexes the DIP joint

Question 27

Tendon exam of the hand: The Thumb

Answer 27

Two extensor tendons (EPL, EPB) and one flexor tendon (FPL)

Question 28

Joint Exam of the Hand

Answer 28

Inspect for swelling, deformity OA will generally affect DIP (Herberden's nodes) and PIP (Bouchard's nodes) RA will affect MP joints and the wrist-all joints can be affected Palpate for warmth, crepitus, clunking, ligament instability, masses Passive motion if patient is unable to perform AROM

For ulnar nerve compression Have pt try to pinch a piece of paper between thumb and index finger If positive, thumb IP will flex and pinch strength will likely be weak

Question 32

Pope's Blessing

Answer 32

Sign of Ulnar nerve compression On inspection, will notice atrophy in the intrinsic muscles, esp between thumb and index finger Will notice clawing of 4th and 5th digits in late disease
