coracoid process, acromion, coracoacromial ligament
what supplies the glenohumeral joint with blood
- anterior circumflex humeral a
- posterior circumflux humeral a
- suprascapular a branches
what supplies the glenohumeral joint with nerves
- suprascapular n
- axillary n
- lateral pectoral n
what are the bursae of the glenohumeral joint
- subacromial
- subdeltiod ( largest in the body)
- subscapular
- subcoracoid
what type of joint is the elbow
hinge type joint
what are the elbows 3 articulation sites
- humero-ulnar
- humero-radial
- radio-ulnar ( proximal)
what is the fibrous capsule of the elbow joint
this is a wak anterior and posterior capsuel that is reinforced by collateral ligaments
What are the ligaments of the elbow joint
- radial collateral
- ulnar collateral
- annular ligament
what does the radial collateral ligament connect too
connects lateral epicondyle of humerus with radius and annular ligament
*smaller then ulnar collateral lig.
what does the ulnar collateral ligament connnect too
connects the medial epicondyle of humerus with ulna
how many bands does the ulnar collateral lig. have
3
- anterior band
- posterior band
- oblique band
- ** many believe that are only two anterior and posterior
what is tommy john surgery
this is where they go in and recreate the elbow lig.
slide 20
what is the carrying angle of the elbow joiont
around 10 to 15 degrees
bursae of the elbow joint
- subcutaneous bursa of medial epicondyle
- subcutaneous bursa of lateral epicondyle
- bursa of anconeus
- bursa at origin of extensor carpi radialis brevis
- olecranon bursae ( subtendinous, intratendinous, subcutaneous)
what supplies the elbow with blood
anastomose aroudn the elbow from
- brachial a.
- deep brachial a.
- ulnar a.
- radial a.
what are the nerve supplies to the elbow joint
articular branches of
- musculocutaneous n.
- radial n.
- ulnar n.
what type of joint is the proximal radio ulnar joint
pivot joint
what ligament is in the proximal radio ulnar joint
annular ligament
what is the blood supply to the proximal radio ulnar joint
- Deep brachial a
- Ulnar recurrent
- *anterior
- *posterior
what is the nerve supply to the proximal radio ulnar joint
musculocutaneous n
median n.
radial n
what type of joint is the distal radio ulnar joint
pivot joint
what ligament is in the distal radio ulnar joint
articular disc ( triangular ligament ) --which attaches to the styloid process of ulna and medial side of distal radius
what is the blood supply of the distal radio ulnar joint
- anterior interossesous a
- posterior interosseous a
what are the nerves of the distal radio ulnar joint
anterior interosseous n
posterior interosseous n
what branch is the anterior interossesous n from
br of median n
what branch is the posterior interossesous n from
deep radial n after supinator m.
What are the joints of the wrist
-radiocarpal joint
what kind of jiont is the radiocarpal joint
condyloid ( ellipsoid) joint
what articulates with the radiocarpal joint
the radius and articular disc of radio ulnar joint articulates with proximal row of carpal bones ( minus the pisiform)
