Adductor pollicis
Interosseous
Medial 2 lumbricals
Palmaris brevis

22
Q

Aka for de Quervain disease

A

Hoffman disease

23
Q

What is de Quervain disease/Hoffman disease

A

Stenosing Tenosynovitis of tendon sheath of abductor pollicis longus and extensors pollicis brevis

24
Q

Dequervain/Hoffman affects who Mc

A

Women 30-60

25
Q

What causes Hoffman/de Quervain

A

Repetitive thumb adduction or extension ulnar wrist deviation

26
Q

What activities cause de Quervain/Hoffman

A

Keyboarding
Filing
Carpentry
Assembly-line worker

27
Q

S/s of de Quervain/Hoffman

A

Pain, tenderness, swelling over first dorsal compartment (increased with thumb movement)

  • swelling over styloid of radius
  • palpable crepitus
  • wrist use causes pain
  • bilateral-30%
28
Q

Dx with pain, tenderness, swelling over first dorsal compartment that increased with thumb motion. Swelling over styloid of radius and palpable crepitus

A

Dequervian/Hoffman

29
Q

Trigger finger

A

Finger gets stuck in bent position

Inflammation narrows space within sheath surrounding tendon

30

RA
Alt: ehlers-Danilo’s, poorly healed fx

32
Q

Boutonnière deformity

A

Flexion-PIP
Extension-DIP

RA
OA

33
Q

Mallet finger

A

Rupture or avulsion of extensor tendon where it inserts into distal phalanx

34
Q

Causes of mallet finger

A

Sports injuries

Especially catching a ball

35
Q

Jersey finger

A

Tear of flexor tendons in finger

36
Q

Causes of jersey finger

A

Contact sports: football/rugby

Gripping a jersey with fingers bent and opponent wrestles away causing forced extension.

Avulsion injury

37
Q

Wrist ROM

A

Flexion: 90
Extension: 70
Ulnar deviation: 55
Radial deviation: 20

38
Q

Tinel sign at the wrist-where

A

Over carpal tunnel and guyon canal

39
Q

Phalen sign: for and what?

A

Back of palms upsidown praying pose for one minute.

+= tingling along median nerve distribution

CTS due to neural ischemia

40
Q

Phalen sign indicates what

A

CTS due to neural ischemia

41
Q

Reverse phalen sign: what? For?

A

Praying position one minute

+ tingling along median

CTS by neural stretch and compression

42
Q

Reverse phalen indicates what

A

CTS by neural stretch and compression

43
Q

Carpal compression test: what? For?

A

Compress carpal tunnel with patients wrist flexed

+ Paresthesia in median nerve distribution

CTS (if less than 15 seconds indicates more advanced)

44

+ bunnel-littler test?

A

Contracture of joint capsule

OA

50
Q

Mannkopf sign

A

Pressure on pain and palpate heart rate

+ increase of 10BPM or more

= pain is organic

51

52
Q

Tests for scaphoid fracture

A
