(5) Upper Extremity Osteology Flashcards
Name this bone:
Superior Surface of the CLAVICLE
Label the Inferior surface of the Clavicle
*Make sure when you label on the practical…
State: “Sternal end of the clavicle”
NOT just “Sternal end”
Label the Inferior View of the Clavicle
Label the Superior View of the Clavicle
CN:
What is the most fractured bone?
Clavicle!!!
*From direct/indirect injuries relatd to falling
CN:
What is a “greenstick” fracture?
Fractures in younger children of clavicle
Incomplete fracture

Name this bone
Humerus
From left to right,
What is the view of the humerus?
What end of the humerus is this?
Proximal end of the humerus
Label the Proximal End of the Humerus
Label the remaining structures on the image of the Proximal Humerus
CN:
Where is the most common fracture site on the Humerus?
Surgical Neck!
CN:
What are the other sites that are susceptible to fractures?
Greater Tubercle, Intraspinatus and Teres Minor Ms. that insert there!
Label the diagram of the Humerus Body
Label the diagram of the Distal end of the Humerus:
Label the diagram of the Distal end of the Humerus
CN:
Describe the expression “funny bone”
The groove for the unlar n. houses the unlar n. and when it is compressed, it is painful.
THIS! Is the origin of the expression “funny bone”;
relates to the presence of the Ulnar N. in this groove on the humerus=funny
CN:
Describe an Avulsion fracture of the Medial Humeral Epicondyle
Severe ABDUCTION of the elbow
Leads to a piece breaking off epicondyle

What are these bones?
CARPALS
8 of them!
Label the Carpal bones
What are the bones of the proximal row of the Carpal B.?
- Scaphoid
- Lunate
- Triquetrum
- Pisiform
What are the bones of the distal row of the Carpal B.?
- Trapezium
- Trapezoid
- Capitate
- Hamate
CN: Which is the most commonly fractured Carpal Bone?
Scaphoid
Label the Anterior Aspect of the Carpal Bones
CN:
Describe what the carpal tunnel is
The passage anterior to the carpal bones
AND
posterior to the flexor retinaculum
CN:
If swelling occurs in the carpal tunnel, what is likely to happen?
Median N. can be compressed resulting in carpal tunnel syndrome
*produces, parasthesia, anesthesia and pain
CN:
The carpal tunnel transmits the following tendons:
- Flexor digitorum profundus
- Flexor digitorum superficialis
- Flexor carpi radialis t.
- Median N.
CN:
What is Guyon Tunnel referring to?
Unlar Canal:
The depression b/w the Pisiform and Hamate
CN:
What is Guyon’s Canal Syndrome?
When ULNAR N. compressed, causes a loss of sensation and muscular weakness
“aka, handlebar neuropathy”
How do you START numbering the Metacarpals?
At the THUMB! That’s number 1
What is the only metacarpal with something “interesting” occuring?
3rd Metacarpal
Has styoloid process on it’s base
CN:
Describe Boxer’s Fracture
The head of the 5th Metacarpal is susceptible to fracture when an individual punches something with a closed fist
