After taping, you want to identify . . .
the subtasks that you're going to assess
What is tertiary intention?
the wound is left open for a time until inflammation is controlled and then surgically closed.
What is secondary intention
the wound is left open to heal on it's own ... used with Dupytren's release sometimes
What is primary intention?
the wound is surgically closed with stitches, staples etc.
Human bites are concerning because . . .
they are highly infectious. (fight bites!)
What are some benefits of wet-to-dry dressings
they are very cheap -> debridement may not be available depending on cost, etc.
Are ganglions around joints palpable?
they can be, but aren't always. Can be hard to palpate, especially in the wrist.
What is open reduction
they cut somebody open and do something inside to realign the bone
What are some negatives of wet-to-dry dressings
they have to be a very compliant patient and used correctly-> e.g., short term only
If the patient is experiencing increasing edema with redness
they need to be referred to a doctor!
What is serosanguinous exudate
thin watery and pink or red
What factors can contribute to tenderness at the coracoid process?
tightness in pectoralis minor, especially as a result of forward shoulder posture.
If you had a patient with no extensor retinaculum, one therapeutic technique you could use in therapy is
to use tape to substitute as the retinaculum and prevent bowstringing
What carpal bone articulates with the first metacarpal
trapezium
What are the muscles of the volar shoulder?
trapezius, deltoid, long head of the biceps, triceps brachii, serratus anterior (scapula)
What does TZ stand for, and where is it?
trapezoid, distal row, between trapexium and captiate.
What is collagen/what does it do in the healing process?
triple helix protein strand that imparts strength to the wound
What does TQ stand for, and where is it?
triquetrium, proximal row closest to pinky.
This carpal bone articulates with the ulna during ulnar deviation
triquetrum.
The adductor pollicis is innervated by the
ulnar n
What innervates the Abductor Digiti Minimi?
ulnar n
Sensation to the dorsal portion of the distal 4th and 1/2 of the 5th fingers is provided by
ulnar nerve
What innervates the interossei?
ulnar nerve
What does a Tinel's at the cubital tunnel mean?
ulnar nerve is irritated.
What is semple's test a test for
ulnar nerve lesion (adductor pollicis)
What is guyon's canal
underneath flexor retinaculum and between hook of hamate and fascia - > can have compression of the ulnar nerve from inflammation
What are the specifications for a securing layer of gauze?
usually "Cling" or sterile gauze roll use figure 8 application ... not too tight ... apply distal to proximal
Are ganglions around joints mobile?
usually Non-mobile; Can disappear with joint movement
Why does vibration cause MSD-UE?
vibration can "turn off" certain receptors; and you no longer have a grasp of how tight you are squeezing
_______________ is one of the first tactile sensations to come back
vibration; tested with middle c.
The first, preferred step of a strain index overview is
videotaping the assessment, but many employers won't allow this
What are ganglions around joints usually filled with?
viscous fluid
What is the distribution of the ulnar nerve in the hand?
volar and dorsal 1/2 of ring finger, small finger --> up to wrist crease
Metacarpals have more material on the (volar/dorsal) side. This causes . . . .
volar; CAM action of the metacarpal, in which the flexion of the proximal phalanx causes the ligaments to become tighter.
If you want a measure of edema of the whole wrist, what is the best method?
volumeter, circumferential. Figure 8 is mostly back of the hand!
What kind of dressings can you use in a yellow wound?
wet to dry dressings and frequent dressing changes
What is dehiscence?
when a well-healed wound starts to separate and break down; fluid often starts to come out (serous, serosanguinous)
What is extensor lag?
when there is a difference between PROM and AROM. Is often in extensor mechanism due to not fully gliding
When do you discharge the MP splint in extensor zone V and VI tendon repair?
when there is no lag of the MPs
immobilization of carpal fractures depends on
which carpal fracture you have
What are drawbacks of whirlpool therapy?
whirlpools are almost impossible to truly sterilize
The wound can be measured in terms of . . .
width and length (and depth c sterile measuring tool)
What is the most common kind of dressings used?
will be the most common form of dressing used: (woven fabric of cotton, rayon or other material) the fabric absorbs drainage and lets air into the wound ... manufacturers may also add antimicrobial agents and other substances to the gauze
What is semple's test
with the finger straight, bring the thumb and the index fingers together
Ganglions on tendons may be associated with. . .
with the synovial sheath or reticulation
Fractures of the distal radius are more common in
women
Radial nerve palsy looks like
wrist drop
What three things are measured in the hand/wrist postures section of the strain index
wrist extension, wrist flexion, ulnar deviation
After 7 weeks, in extensor zone II-IV tendon repair, you should
you may begin passive flexion, but watch for that extension lag (gutter at night)
After you identify multipliers, you
you multiply together to find strain index score
When you remove the pressure on a low-load long stretch
you want it to hurt a little bit! it means you did something (but it shouldn't hurt when it's on.)
Should you use zinc to on a wound?
zinc products promote wound healing
In zones ___________, the extensor tendons are not restrained to the muscles
zones 7, 8
