19
Q

AAI of pronator quadratus?

A

Attachments- anterior surface of the distal ulna to the anterior surface of the distal radius

Innervation- median Nerve

Spinal Segments- C8-T1

20
Q

What is the synovial joint classification for the proximal radio-ulnar joint?

A

pivot or trochoid

21
Q

What are the clinically important bursae of the elbow?

A

The 3 olecranon bursae

22
Q

Where is the intratendinous olecranon bursa?

A

Sometimes present in the tendon of triceps brachii

23
Q

Where is the subtendinous olecranon bursa?

A

Between the olecranon and the triceps tendon, just proximal to its attachment at the olecranon

24
Q

Where is the subcutaneous olecranon bursa?

A

In the subcutaneous connective tissue over the olecranon.

25
Q

What is the function of the bicipitoradial bursa?

A

Separates the biceps tendon from and reduces friction against the anterior part of the radial tuberosity.

26
Q

What is radial head subluxation?

A

Usually seen in ages 3-5, when the upper limb is suddenly pulled while forearm is pronated. The force tears the distal attachment of the anular ligament around the neck of the radius which causes the radius to move distally out of the socket. “nurse maid’s elbow”

27
Q

What is olecranon bursitis?

A

Can be caused by falls to the elbow or repeated excessive pressure and friction to elbow. This causes the bursa to become inflamed. AKA “dart thrower’s elbow” or “miner’s elbow”

28
Q

What neurovascular structures would be injured based on bone fracture located at the medial epicondyle of the humerus?

A

Ulnar nerve, Medial cutaneous nerve of the forearm, Superior ulnar collateral artery, anterior ulnar recurrent artery

29
Q

What are the attachments of flexor carpi ulnaris?

A

From the medial epicondyle and proximal ulnar shaft to the pisiform

30
Q

What are the attachments of flexor carpi radialis?

A

The medial epicondyle (common flexor origin) to the palmar aspect of the base of the 2nd metacarpal.

31
Q

What are the attachments of flexor digitorum profundus?

A

Anterior proximal 2/3 of the ulna and interosseous membrane to the base of the distal phalanges digits 2-5.

32
Q

What are the attachments of flexor digitorum superficialis?

A

Medial epicondyle to the sides of the middle phalanges of digits 2-5

33
Q

What are the attachments of flexor pollicis longus?

A

Anterior surface of the radius and interosseous membrane to the base of the distal phalanx of the thumb

34
Q

What are the attachments of palmaris longus?

A

The medial epicondyle to the palmar aponeurosis

35
Q

What are the attachments of pronator teres?

A

Medial epicondyle and ulnar coronoid process to lateral aspect of the radius

36
Q

What are the attachments of pronator quadratus?

A

Anterior surface of the distal ulna to the anterior surface of the distal radius

37
Q

What are the spinal segments of flexor carpi ulnaris?

A

C7-T1

38
Q

What are the spinal segments of flexor carpi radialis?

A
