Q

test and intervention for de quervains

A

Finklestein’s (hold thumb in fist and ulnarly deviate)

forearm thumb spica cast (IP free), steroid injection, activity modification, ice massage over radial wrist, gentle AROM of wrist and thumb to prevent stiffness

surgery to release first dorsal compartment

21
Q

Dupuytren’s

A
  • disease of the fascia of the palm and digits; becomes contracted and results in flexion deformities in the digits
    intervention: fasciotomy with z-plasty, aponeurotomy, enzyme injections

OT intervention: wound/scar care, edema control, extension splint (full is ideal, but consult with surgeon), ROM and progress to strengthening, grip/release

22
Q

Skier’s/gamekeepers thumb

A
  • rupture of ulnar collateral ligament of MCP joint of the thumb
  • most common cause is fall while skiing with thumb held in the ski pole
  • intervention: thumb splint 4-6 weeks, AROM and pinch strength at 6 weeks, PROM 8 weeks, strengthen at 10
23
Q

complex regional pain syndrome (CRPS)

A
  • vasomotor dysfunction as a result of an abnormal reflex
    may follow trauma or surgery, but actual cause is unknown
    s/s: severe pain, edema, discoloration, temp and tropic changes, vasomotor instability

intervention:
1. Stress loading: compress the joint, then distract it
2. Reduce pain with gentle AROM and desensitization
modalities to reduce pain, splinting to prevent contractures

  • Modalities to decrease pain: use contrast baths to facilitate opening and closing of vessels is preferred modality
  • edema management
  • ADLs to encourage pain free active use
24
Q

colles fracture

A

fracture of distal radius with dorsal displacement

25
Q

smith’s fracture

A

fracture of distal radius with volar displacement

26
Q

carpal fractures

A

(scaphoid most common)

27
Q

boxer’s fracture

A

fracture of 5th metacarpal
ulnar gutter splint

28
Q

proximal phalanx fx

A

most common is thumb and index

29
Q

distal phalanx fx

A

most common finger fx
mallet finger

30
Q

OT evaluation for fractures

A

occupational profile, history of injury, special test results, edema, pain, AROM (*no PROM or strength until ordered by physician)

31
Q

intervention for fractures

A
  1. immobilization phase: stabilization and healing (splint and one arm techniques, AROM, edema control, light ADLs)
  2. mobilization phase: consolidation is the goal (edema control, AROM then PROm then strength - usually start with isometric exercises)
32
Q

cumulative trauma disorders

A

repetitive strain injuries
ex: de quervains, lateral and medial epicondylitis, trigger finger

33
Q

lateral epicondylitis
medial epicondylitis

A

tennis elbow - overuse of wrist extensors
golfer’s elbow - overuse of wrist flexors

tx:
- elbow strap, wrist splint
- ice and deep friction massage
- stretching
- activity/work modification
- as pain decreases, add strengthening. begin with isometric exercises, then progress to isotonic and eccentric

34
Q

trigger finger

A

tenosynovitis of finger flexors (most common A1 pulley)

tx:
- hand or finger based trigger finger splint (MCP extended, IP free)
- scar massage
- edema control
- tendon gliding
- activity modification (avoid repetitive gripping activities)

35
Q

carpal tunnel

A

compression of median nerve
etiology: repetition, awkward postures, vibrations, pregnancy
s/s: tingling (at night) and numbness of thumb, index, middle, and radial 1/2 ring finger, weakness

36
Q

carpal tunnel tests

A

tinel’s sign (tapping)
phalen’s (dorsal hands together)
durkan’s (press thumbs on carpal tunnel, have s/s)

37
Q

tx carpal tunnel

A

conservative: splint in neutral, nerve gliding, activity modification, modalities
surgical: carpal tunnel release

38
Q

pronator teres syndrome

A

compression of median nerve between 2 heads of pronator teres
- positive tinel’s sign at the FOREARM, not the elbow, no night symptoms

39
Q

Guyon’s canal

A

ULNAR nerve compression at the wrist
s/s: numbness and tingling in ulnar nerve distributions of the hand, motor weakness, positive tinnels at the canal
impairs hypothenar muscles - difficulty turning key/lateral pinch

40
Q

cubital tunnel syndrome

A

ulnar nerve compression at the elbow
weakness, numbness on ulnar elbow/forearm, positive tinels at elbow

41
Q

adhesive capsulitis

A

frozen shoulder
restricted passive shoulder ROM
etiology: inflammation, immobility, diabetes, parkinsons
conservative intervention: active use through light ADLs, PROM, modalities
surgical: arthroscopic

42
Q

positioning and isometric

A

o Positioning: start at BOS (pelvis)
o Isometric: M, but no movement
o Isotonic: move a G&T to your mouth

43
Q

CRPS interventions to avoid or use with caution

A

PROM, passive stretching, joint mobilization, dynamic splinting, and casting

44
Q

fracture that is exception with PROM

A

humerus fractures often begin with PROM or AAROM

45
Q

intervention for pronator trees syndrome

A

conservative: elbow splint at 90 deg with forearm in neutral, avoid activities that include repetitive forearm pronation and supination
surgical: decompression

46
Q

guyon’s canal intervention

A

conservative: wrist splint in neutral, work/activity modification
surgical: decompression

47
Q

cubital tunnel intervention

A

conservative: elbow splint at 30 deg of flexion, especially at night, elbow pad to decrease compression of nerve when leaning on elbows, activity/work modification
surgical: decompression or transposition

sensory reeducation

A

begin when individual demonstrates a level of diminished protective sensation (4.31) on femmes-weinstein
