-due to bony overgrowth a/w OA

-usually hard and painless 

-affect middle aged to  elderly

what are Bouchard's nodes?

found on the PIP joints and are less common than Heberden's nodes

16

tender, stiff joints of both hands

PIP, MCP and  wrist joints but NOT DIP

spindle shape swelling of PIP

rheumatoid nodules

symmetrically affects

17

what are signs of chronic RA?

swelling and thickening of PIP and MCP

limited ROM

fingers deviate to ulnar side

interosseous muscle atrophy

swan neck deformities

boutenniere deformities

rheumatoid nodules

18

what is a ganglion?

fluid filled sac that forms by irritation, usually non-tender located along tendon sheaths or joint capsules

-frequently found on dorsum of wrist

19

what is tenosynovitis?

inflammation of flexor tendon sheaths may follow local injury

-tenderness and swelling along course of flexor tendon distal phalynx to MCP w/o joint involvement

-early dx and treatment are important

20

what is a felon?

injury to finger tip that damages finger pad

-severe pain, local tenderness

-early dx is important

21

what is dupuytren's contracture?

skin puckers in the area of flexor tendon of the ring and maybe the little finger

-flexion of contracture may ensue

22

what is a trigger finger?

painless nodule in a flexor tendon in the palm near the head of the MC

-audible snap is present when nodule tries to move through tendon sheath (can't back the tendon out)

-watch and listen during flexion and extension and palpate for the nodule and the snap
