30
Q

retrograde blood flow

A

scaphoid #

if proximal- chance of necrosis because blood travels distal first and then proximal

31
Q

blood supply to fingers

A

radial and ulnar arteries

superior and deep palmar arches

32
Q

finkelsteins

A

DeQuervain’s Tenosynovitis

pt makes a fist and then deviates into ulnar deviation
sharp pain is evidence of stenosing tenosynovitis
pain over carpal tunnel - median nerve

33
Q

tinel sign (wrist)

A

carpal tunnel
tapping over the transverse carpal ligament- which causes tingling and parasthesia over the thumb, indea, middle and ring finger - median nerve

34
Q

phalens test

A

wrist are bent down with backs of each hand touching

carpal tunnel sufferers feel tingling or pain within 60 seconds

35
Q

allens test

A

occlude both ulnar and radial artery until hand blanches then release ulnar. If the
hand pinks up, ulnar artery is good and you can carry on with ABG/radial stick as planned. ABGS
must be put on ice and whisked to the lab.

36
Q

tfcc injury

A

MOI: torque or violent twist, foosh
ulnar pain
wrist extension is difficult
clicking or catching and considerable swelling

37
Q

drop wrist

A

radial nerve palsy

38
Q

benediction deformity

A

wasting of the hypothenar, dorsal interossei, and fourth and fifth lumbrical muscles resulting from ulnar nerve palsy (bishops deformity)

39
Q

claw hand

A

ulnar nerve laceration, MCP flexion block splint

40
Q

ape hand

A

median nerve palsy

41
Q

dequervains syndrome

A

painful condition at the wrist on the side closer to the thumb resulting from tendons trapped beneath a ligament as they travel to the thumb

42
Q

kienbock disease

A

avascular necrosis of the lunate

43
Q

preisers disease

A

avascular necrosis of the scaphoid

44
Q

wrist ganglion

A

herniation of the joint capsule or synovial sheath of a tendon
soft, rubbery, or very hard

45
Q

boutonniere deformity

A

flexion of PIP and hyperextension of DIP joint

46
Q

dupuytrens contracture

A

thickening and shrinking of the fascia of the palm with fingers being drawn into a flexed position

47
Q

jersey finger

A

an injury to the finger resulting in tearing of the flexor tendon in the fingertip

48
Q

game keeps thumb

A

injury to thumb that results in tearing or stretching of the MP joint or rupture of the ulnar collateral ligament

49
Q

swan neck deformity

A

hyperextension of the PIP and flexion of DIP
