Joints of the Upper Extremity UE5 Flashcards

1
Q

synovial joints

A
  • most common type of joint in the body
    ~consist of a joint cavity with articulating surfaces of bones

The six types:
- plane joints
- hinge joints
- pivot joints
- condyloid joints
- saddle joints
- ball and socket joints

Q

sternoclavicular joint

A
  • saddle-type joint
  • strong, but mobile joint
  • transfers forces to the axial skeleton
  • only joint of the UE which is connected to the axial skeleton
  • location is between the proximal aspect of the clavicle and manubrium of the sternum

Q

what does the movement at the SC joint depend on?

A

movement at this joint relies primarily on the motion of the scapula and the pectoral girdle

  • no muscles have immediate action on the SC joint.

16
Q

acromioclavicular (AC) joint

A
  • plane synovial joint
  • located between the lateral clavicle and acromium of scapula
  • allows limited side to side gliding motion between scapula and clavicle
  • provides stability to the shoulder
  • transmits forces from the upper limb to the axial skeleton
17
Q

ligaments of the AC joint

A
  • coracoclavicular ligament
  • acromioclavicular ligament
18
Q

coracoclavicular ligament

A
  • anchors the clavicle to the coracoid process of the scapula
  • consists of two ligaments: conoid and trapezoid
  • helps suspend the scapula and limb from the clavicle
19
Q

acromioclavicular ligament

A
  • extends from the acromion to the clavicle
  • strengthens the AC joint superiorly
20
Q

glenohumeral joint

A
  • ball and socket joint
  • the humeral head articulates with
    the shallow glenoid cavity of the
    scapula
  • wide range of motion, but not very
    stable
    ~ laxity of the joint capsule
    ~ large size of the humeral head
    compared to the small size of the
    glenoid cavit
21
Q

glenoid labrum

A
  • fibrocartilage
  • deepens glenoid cavity and assists with stability
  • suction effect
  • tearing = instability
  • blends with ligaments & long head of biceps brachii tendon
22
Q

glenohumeral ligaments- static stabilizers

A
  • glenohumeral ligaments
  • coracohumeral
  • transverse
  • coracoacromial
23
Q

glenohumeral ligaments

A
  • primary stabilizers of the joint
    ~ 3 fibrous bands
    ~ reinforce the joint anteriorly
    ~ make up the fibrous capsule of the joint
24
Q

coracohumeral ligament

A
  • base of the coracoid process to the greater/lesser tubercles of the humerus
  • reinforces joint superiorly, merges with tendon of supraspinatus
25
Q

transverse humeral ligament

A
  • greater to the lesser tubercle of the humerus
  • helps keep the tendon of the long head of the biceps brachii in place.
26
Q

coracoacromial ligament

A
  • coracoid process of scapula to the acromium of scapula
  • reinforces joint superiorly
  • prevents superior dislocation of the humerus
27
Q

ligaments of the elbow

A
  • radial collateral ligament
  • ulnar collateral ligament
28
Q

radial collateral ligament

A
  • lateral epicondyle of humerus to annular ligament of radius
  • reinforce the elbow during flexion-extension
29
Q

ulnar collateral ligament

A
  • medial epicondyle of humerus to coronoid process and olecranon of ulna
  • reinforce the elbow during flexion-extension
30
Q

radio ulnar joint

A
  • pivot Joint
  • movements
  • pronation-supination
  • the radius moves around the fixed ulna
31
Q

proximal radio- ulnar joint

A
  • head of radius articulates with the radial notch of ulna
  • annular ligament-holds the head of the radius in the radial notch of the ulna
32
Q

distal radio-ulnar joint

A

distal radius articulates with the head of the ulna

33
Q

joints of the hand

A
  • radiocarpal (wrist)
  • intercarpal/Midcarpal
  • carpo-metacarpal (CMC)
  • metacarophalangeal (MCP)
  • interphalangeal
  • PIP, DIP
34
Q

carpometacarpal (CMC) joints

A

distal carpal bones articulate with metacarpals

35
Q

CMC thumb saddle joint

A
  • flexion/ extension
  • abduction/ adduction
  • opposition
36
Q

digits 2-5 plane joints

A
  • gliding motion
  • almost no movement occurs at the 2nd and 3rd digits
  • the 4th digit is slightly mobile
  • the 5th digit is moderately mobile
37
Q

joints of the fingers

A
  • MCP joints
  • IP joints (PIP and DIP)
38
Q

MCP joints

A
  • condyloid joint
  • flexion–extension and adduction–abduction.
  • MCP joint of the thumb is limited to flexion–extension.
39
Q

Ip joints (PIP and DIP)

A
