21
Q

What does the dorsal tubercle do

A

Acts as a pulley for the extensopr and pollicis longus M.

22
Q

What are the bones of the proximal row of the carpal bone

A

Scaphoid
Lunate
Triquetrum
Pisiform

23
Q

What is the most commonly fractured carpal

A

The scaphoid bone

24
Q

Severe abduction of the extended elbow can result in what

A

Avulsion of the medial humeral epicondyle

25
Q

What is a fracture of the elbow?

A

A fracture of the olecranon, an avulsion fracture

26
Q

What is a Colle’s fracture

A

A fracture of the distal end of the radius

Presents as the bent fork

27
Q

What is a break of the scaphoid bone usually from? Why is it usually misdiagnoed

A

Usually from falling. Misdiagnosed as a sprain bc not well seen on X-ray

28
Q

What dos the lunate do

A

Articulate with the radius

29
Q

What is the passage anterior to the carpal bones and posterior to the flexor retinaculum known as and what is the clinical significance

A

The carpal tunnel

Swelling here causes carpal tunnel syndrome

30
Q

What is the largest carpal bone

A

The capitate

31
Q

How many middle phalanges are there

A

Only 4, compared to the others have 5 for everything else

32
Q

What is a boxer’s fracture

The end of the 5th metacarpal is broken

33
Q

A

The anatomical lateral portions (1 - 3)

34
Q

Where will you have pain with Guyon’s canal syndrome

A

The medial two

35
Q

What is the depression between the pisiform and hamulus of the hamate known as and what is the clinical significance

A

Known as guyon tunnel

Ulnar nerve passes through here and is susceptible to compression and pain

36
Q

What usually tears from someone throwing a ball

A

The glenoid labrum

This us due to a sudden retraction of the biceps brachii M.

37
Q

What types of fractures and where are especially common in children

A

Green stick fractures of the clavicle

38
Q

What is the weakest part of the clavicle

A

The junction of its middle and lateral thirds

39
Q

What happens after fractures of the clavicle

A

The sternocleidomastoid muscle elevates the medial fragments of the bone

40
Q

What so the first bone to ossify and at what week in development

A

The clavicle at week 5

41
Q

Fracture of the scapula is usually due to what

A

Severe trauma

42
Q

Most fractures of the scapula involve what

A

The acromion

43
Q

Fracturs of ths urgical neck are expecially common in what population

A

The elderly with osteoporosis

44
Q

What is an impacted fracture

A

Bone fragment pushed into the spongy part of itself

45
Q

An avulsion fracture of the greater tubercle of the humerus is usually seen in who

A

Middle-age and elderly people

46
Q

What does an intercondylar fracture result from and what happens

A

A severe fall on the flexed elbow

The olecranon of the ulna is driven like a wedge between the medial and lateral parts of the condyle of the humerus, separating them.

47
Q

Fractures of the distal end of the humerus are common in who

A

Adults >50

48
Q

For colles fracture, what type of fracture is it

A

A complete transverse fracture of the distal radius
