Q

What ligaments are around the GH jt and what do they do?

A
  1. glenohumeral ligament - superior, middle and inferior; three weak bands of fibrous tissue that strengthen the front of the capsule
  2. coracohumeral ligament - strengthens the capsule above and stretches from the root of the coracoid process to the greater tuberosity of the humerus
  3. transverse humeral ligament - strengthens the capsule and bridges the gap between the two tuberosities.

25
What is the classification of the humeroulnar/humeroradial joints?
``` structure - synovial function - diarthrotic subtype - hinge axis - uniaxial ```
26
What is the ROM for the humeroulnar/humeroradial joints?
flexion: 135 degrees extension: up to 5 degrees
27
What is the resting position for the humeroulnar jt?
70 flexion and 10 supination
28
What is the closed pack for the humeroulnar jt?
full extension and supination
29
what is the capsular pattern for the humeroulnar jt?
flex > extension (flexion is more limited than extension)
30
What is the resting position for the humeroradial jt?
full extension and supination
31
what is the closed pack position for the humeroradial jt?
90 flexion, 5 supination
32
what is the capsular pattern for the humeroradial jt?
flex > extension (flexion is more limited than extension)
33
What is the carrying angle in men? in women?
5 degrees in men. 10-15 degrees in women
34
Which are convex and concave in the humeroulnar/humeroradial joints?
capitulum and trochlea = convex articular surface of radial head = concave trochlear notch = concave
35
Name the ligaments around the humeroulnar/humeroradial joints and where they are located.
1. radial collateral ligament - lateral epicondyle to annular ligament and margins of the radial notch 2. ulnar collateral ligament - meidal epicondyle of humerus to the coronoid process and olecranon of the ulna
36
What innervates the humeroulnar/humeroradial joints?
- musculocutaneous n. - radial n. - median n.
37
What is the angiology of the humeroulnar/humeroradial joints?
brachial, ulnar and radial arteries
38
what does traction/distraction of the humeroulnar jt improve?
flex/ext.
39
Why is the hip JT much more stable than the GH it?
The acetabularfemoral JT is much more stable due to: - a negative intra-capsular atmospheric pressure(suction), a stronger JT capsule, a more specific femoral head and a deeper socket- made even deeper by the labrum(=a better fit)
40
Where do most functional activities of the hip occur in ( in terms of degrees)?
Most functional activities occur between 0-120 degrees of hip flexion and between 0-20 degrees of lateral rotation and abduction.
41
What is the structural classification of the hip?
The acetabularfemoral ( aka the hip) is structurally classified as a synovial joint. It's sub-type is a ball and socket. It is multiaxial.
42
What is the functional classification of the hip?
The functional classification of the hip is diarthrotic.
43
How much ROM does the hip have in flexion, extension, abduction, adduction, medial rotation and lateral rotation?
``` Hip JT ROM: Flexion=120* Extension=30* Abduction=45* adduction=30* Medial rotation=35* (limited by ischiofemoral lig.) Lateral rotation=45* (limited by pubofemoral and iliofemoral ligaments) ```
44
What is the resting position of the hip JT?
30* flexion, 30* abduction, and lateral rotation
45
What is closed pack position for the hip?
Full extension, abduction, and medial rotation
46
What is the capsular pattern of for the hip joint?
Internal rotation and abduction> flexion and extension> external rotation (which is relatively free.) (internal rotation/abduction are more limited than flexion/extension which is more limited than ext rotation.)
47
What are the articular surfaces of the hip JT?
``` Femoral head (convex) And acetAbulum (concave) ```
48
What is the capsular strength of the acetabular femoral joint?
It is STRONG due to zona orbicularis (which are the circular fivers of the articular capsule)
49
What ligaments are associated with the hip JT?
1. ) ligament Capitis femoris 2. ) iliofemoral ligament 3. ) pubofemoral ligament 4. ) ischiofemoral ligament 5. ) transverse acetabular ligament 6. ) zona orbicularis
50
What blood vessels and nerves are associated with the hip JT?
Femoral, obturator and gluteal nerves and arteries are associated with the hip JT.
51
What joint mobs can be done on the hip JT?
1. ) distraction 2. ) long-axis traction/inferior glide 3. ) posterior glide 4. ) anterior glide 5. ) postero-lateral glide of femur in pelvis 6. ) lateral glide
52
What movement does long-axis traction/inferior glide aid the hip JT with?
Abduction
53
What movement does posterior glide aid the hip JT with?
Flexion and medial rotation
54
What movement does an anterior glide help with the hip JT?
Extension, and lateral rotation
55
What movement does postero-lateral glide of the femur on the pelvis have on the hip JT?
Medial rotation
56
What movement does lateral glide have on the hip JT?
Adduction and medial rotation
