Practical Exam Ligaments Flashcards
(29 cards)
1
Q
Elbow MCL
A
- taut in valgus force
- push medially on humerus
- anterior is taut in ext and flexion
- post taut in flexion
- transverse doesn’t do shit
2
Q
Elbow LCL
A
- taut in varum force
- push laterally on humerus
- radial and ulnar component
- radial humerus to radius
- ulnar humerus to ulna
3
Q
Annular Lig
A
- around radial head
- taut in supination and longitudinal distraction
4
Q
Oblique Cord
A
- inbetween ulnar and radius proximally
- limits pronation/supination
5
Q
Interosseous
A
- limits superior glide of radius
6
Q
Dorsal radioulnar
A
- right between radius and ulna
- limits pronation
7
Q
Palmar radioulnar
A
- right between radius and ulna
- limits supination
8
Q
Knee MCL
A
- taut in valgus force
- push medially on femur
9
Q
Knee LCL
A
- taut in varus force
- push laterally on femur
10
Q
Knee ACL
A
- taut in anterior translation of tibfib
- pull tibfib anteriorly while sitting hookline
11
Q
Knee PCL
A
- taut in posterior translation of tibfib
- push tibfib posteirorly while sitting hookline
12
Q
Wrist LCL
A
- limits ulnar deviation
13
Q
Wrist MCL
A
- limits radial deviation
14
Q
Dorsal radiocarpal
A
- limits wrist flexion
- radius to pinkly met
15
Q
radial and ulnar cord
A
- taut in extension/hyperextension of METS, PIP, DIP
16
Q
radial and ulnar accessory
A
- taut in flexion/hyperflexion of METS, PIP, DIP
17
Q
check rain
A
- only in PIP and DIP
- limits hyperextension
18
Q
Iliofemoral
A
- Y ligament
- taut in extension and external rotation
19
Q
Pubofemoral
A
- taut in extension, abduction, external rotation
20
Q
Ischiofemoral
A
- taut in extension, internal rotation, adduction
21
Q
MCL/Deltoid of foot
A
- taut in rear foot eversion
22
Q
Calcaneofibular
A
- limits DF and inversion
23
Q
Cervical lig
A
- taut in supination/inversion
24
Q
Talocalcaneal
A
- limits eversion/pronation
25
LCL of ankle
- limits rear foot inversion
26
Superior GH
- taut when pushing arm down out of joint (inferior translation), taut in anterior-posterior and inferior
27
Middle GH
- taut in anterior translation, limits ext rotation
28
Inferior GH
- anterior band: limit anterior translation (so externally rotate arm) when abd at 90deg
- posterior band: limits post during medial/internal rotation (internally rotate arm)
- axillary pouch: resists inferior translation when in 90deg abd
29
Coracohumeral lig
- limits inferior translation when arm dependent
| - limits external rotation when arm is adducted preventing superior translation of humeral head
