Exercise management of RA:
- Gripping/ resistive exercises | - ROM exercises
26
Joint protection for RA:
- splinting | - activity modification
27
What is dupuytren contracture?
- Nodule formation palmar/ digital fascia - Pitting of skin observed - Impairs motion
28
Natural course of dupuytren contracture?
1. “Cord” structures cause contractures and impaired motion of tendons - MCP & PIP commonly affected - Less commonly affected DIP 2. Thickening/ shortening of fascia
29
Risk factors for dupuytren contracture?
- Caucasian - Increasing age - Male gender (7-15x > women) - Alcoholism - DM - Smoking - Hand trauma/ Sx
30
Which digit most commonly affected by dupuytren contracture?
5th (70%)
31
T/F Dupuytren contracture is commonly bilateral.
True
32
MOI of wrist/hands sprains:
Force to wrist exceeding normal range
33
Consider fracture of what with wrist/hands sprains?
Carpal fracture
34
Symptomology of wrist/hands sprains:
- Local pain that resides & returns - Swelling - ecchymosis (bruising) - tenderness - pain with movements that place tensile load (stretch) on sprained structure
35
Gamekeeper's thumb -
Sprain of 1st MCP - ulnar collateral lig sprain
36
MOI of Gamekeeper's thumb:
- Valgus moment to 1st MCP | - skiing injury
37
Physical examination of Gamekeeper's thumb:
Local tenderness/ swelling | +Ulnar collateral ligament test
38
T/F Healing of TFCC lesion more likely if more superficial.
True, better vascular supply
39
Common MOI of TFCC lesion:
- FOOSH | - Repetitive pronation/ supination with loading
40
Physical Examination of TFCC lesion:
- Medial wrist pain (with opening door) - Clicking/ popping with wrist motions - Tenderness in area of TFCC - Swelling with more acute trauma - A/PROM painful/ limited ulnar deviation (also supination with ulnar deviation position to start) - Pain/ tenderness with mobility testing of radiocarpal joint with ulnar deviation bias
41
What is intercarpal instability?
- Disruption/damage of interosseous &/or mid-carpal ligaments - Independent movement of carpals
42
What is dissociative intercarpal instability?
Involves carpals of the same row
43
What is Dorsal Intercalated Segment Instability (DISI)?
- Scapholunate dissociation - Dorsal tilt of lunate - Lunate remains connected to triquetrium, but not scaphoid - Lunate no longer follows scaphoid into flexion
44
What is Volar Intercalated Segment Instability (VISI)?
- Lunotriquetrum dissociation - Volar tilt of distal lunate - Lunate remains connected to scaphoid, but not triquetrium
45
Physical examination of Dorsal Intercalated Segment Instability (DISI):
- FOOSH extension/ ulnar deviation - Pain/ weakness with Grasping - Tenderness over scaphoid/ lunate - Laxity with joint mobility testing
46
T/F Volar Intercalated Segment Instability (VISI) presents very similarly to DISI.
True
47
Where does tendinopathy of extensors of wrist and fingers occur?
- Intersection Syndrome (ECRL & ECRB where crossing deep to APL & EPB) - Tenderness 6-8 cm proximal to Lister’s tubercle

- Typically insidious onset | - Microtrauma MOI
49
Physical examination of tendinopathies:
- Tender locally - Painful with tensile loading (stretching): P/AROM and resistive testing - Possibly palpable thickening of tenosynovium - Crepitus with tendon moving through tendon sheath
50
What is trigger finger?
Enlargement of tendon/ pulley affecting tendon as it pistons through A1 pulley (nodule gets caught in flexion)
51
Trigger finger typically where in hand?
MC head
52
What digit most common for trigger finger?
3rd
53
Risk factors for trigger finger?
- DM - young children - menopausal women - RA
54
Physical examination of trigger finger:
- C/o Painful snapping at MCP area during flexion/ extension motions of fingers - Limited/ painful finger motion - Crepitus with motion (palpable vs. auditory)
55
What is De Quervain's Tenosynovitis (DQT)?
- Disorder involving the tendons of the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) tendons - Thickening of soft tissue structures surrounding the involved tendons = impaired tendon gliding
56
T/F No active inflammatory process with De Quervain's Tenosynovitis (DQT).
True
57
Prevalence of DQT:
Men: 0.5% - 0.7% Women: 1.3%- 2.1%
58
Associated patient demographics of De Quervain's Tenosynovitis (DQT):
- Female Gender - Work-related injury (texting, typing, tracker ball mouse) - Computer users who use a mouse or trackball - Text messaging - Repetitive fine-motor task (typing)
59
Physical examination of De Quervain's Tenosynovitis (DQT):
1. Local Tenderness 2. Painful ROM that places tensile load (stretch) on APL & EPB (AROM - abduction/extension worse – not so bad PROM) 3. + Finkelstein’s Test 4. Painful resistance testing APL & EPB
60
What is a ganglia?
- Thin-Walled cyst over joint capsule/ tendon sheath - Filled with mucoid hyaluronic acid (spontaneous) - Possible compression on ulnar/ median nerves
