Q

What occurs during an acromiclavicular dislocation

A

The two articualting surfaces of the joint are separated typically by falling on an outstretched hand or a direct blow to the joint.

the injury is made more serious if there isan associated ligament rupture. This may require surgery for a full recovery

Q

What two important bursae are found in the shoulder?

A

Subacromial- located deep in the deltoid and acromion, superficial to the supraspinatous tendon and the joint capsule. Subacromial bursitis can be cause shoulder pain

Subscapular- located between the subscapularis tendon adn the scapula it reduces wear and tear on the tendon during movement at the shoulder joint

Q

What is the elbow joint?

A

Hinge synovial joint between the radius ulna and humerus It consists of two seperate articulations:

Capitulum to head of radius
trochlea to trochlear notch

17
Q

What are the clincially important bursae of the elbow

A

Intratrndinous (within triceps tendon)
Subtendinous (between olecranon and triceps)
Subcutanous (between olecranonand connective tissue)

18
Q

What ligaments strengthen this joint

What movements occur at these joints?

A

Ulnar collateral ligament
Radial collateral ligament

Extension-triceps
Flexion- biceps, brachialis, coracobrachialis

19
Q

What types of bursitis may occur at the elbow?

A

Subcutaneous bursitis- may become infected

Subtendinous bursitis- typically factory workers

20
Q

What is epicondylitis

A

Swelling of the epicondyle of tendionous origin. Results in pain and inflammation due to an overuse strain.

Golfers elbow- medial epicondyle (middle of fairway)
Tennis elbow- lateral epicondyle (lateral line of court)

21
Q

What is epicondylitis

A

Swelling of the epicondyle of tendionous origin. Results in pain and inflammation due to an overuse strain.

Golfers elbow- medial epicondyle (middle of fairway)
Tennis elbow- lateral epicondyle (lateral line of court)

22
Q

What is the radioulnar joint?

A

The two locations where the radius and ulnar join. Proximal (near elbow) and distal (near wrist)

They are both synovial pivot joints

23
Q

What surrounds the proximal radioulnar joint capsule

What movements occur at both radioulnar joints?

A

Annualar ligament- hook around joint capsule

Pronation and supination

24
Q

What is the interosseous membrane?

What are its three main functions?

A

Sheet of connective tissue between the radius and ulna

Holds radius and ulna together
site of attatchemnt for muscles of forearm
transmits force from radius to ulna

25
Q

What commonly happens during radial ulnar fractures

What are the two most common fractures?

A

Like a polo mint it is hard to break one side without breaking the other

Monteggias- force from behind ulna fractures proximal shaft and dislocates head of radius

Galeazzis fracture- fracture to distal radius which dislocates ulna head at distal radio-ulnar joint

26
Q

What joint occurs at the wrist

A

Joint between the radius and the proximal carpal bones. Also termed the radiocarpal joint it is a synovial ellipsoid joint

NOTE the ulna is not part of the wrist joint, it is prohibited from articulating by the articular disc

27
Q

What ligaments support this joint

A

One at each surface

Palmar radiocarpal
Dorsal radiocarpal
ulnar collateral
radial collateral

28
Q

What movements occur at the wrist joint?

A

Flexion
Extension
Adduction
Abduction

29
Q

What is Colle’s fracture?

A

Most commo fracture involing the wrist caused by falling on an outstretched hand.

Leads to dinner fork deformity due to displacement of the radius being fractured posteriorly

30
Q

What occurs during a scaphoid fracture?

A

Caused by falling on outstretched hand. Leads to pain and tenderness in the anatomical snuffbox

May lead to avascular necroses due to distal to proximal blood flow. May also lead to osteoathritis later in life
