AC Jt. Separation/dislocation - ANSWER:Separation:
Trauma to the upper shoulder region resulting in partial or complete tear of the
acromioclavicular or coracoclavicular ligament or both ligaments (can be anteriorly)
Dislocation:
injury in which the distal clavicle usually is displaced superiorly
Hill-Sachs defect - ANSWER:A compression fracture of the articular surface of the
posterolateral aspect of the humeral head
Bankart lesion - ANSWER:lesion of the anteoinferior aspect of the glenoid labrium
this type of injury is often caused by anterior dislocation of the proximal humerus
(scapula)
Osteoarthritis - ANSWER:also called degenerative jt. disease is a non-inflammatory
joint disease characterized by gradual deterioration of the articular cartilage with
hypertrophic bone formation most common type of arthritis
Osteoporosis - ANSWER:osteoporosis and resultant fractures are due to a reduction
in the quantity of the bone or atrophy of skeletal tissue bony trabeculae is scanty
and thin
Shoulder Discoration - ANSWER:traumatic removal of humeral head from the glenoid
cavity 95% of these dislocation are anterior
Coronoid fossa is... - ANSWER:an anterior shallow depression
Capitulum is the cap on the rad so on which side is the capitulum? - ANSWER:the
radial side
what projection do we palpate the medial and lateral epicondyles? - ANSWER:AP
they need to be parallel
Lateral they need to be perpendicular
Which projection can you best view olecranon? - ANSWER:Lateral
Olecranon process is fracture often as a... - ANSWER:fall (off the monkey bars)
for the lateral elbow you flex the arm and you can see the ____________ and
____________ - ANSWER:coronoid process and the radial head
What 3 things do we recognize for a true lateral - ANSWER:The three concentric arcs
,What are the three concentric arcs? - ANSWER:1. trochlear sulcus
2. outer ridges of capitulum and trochlea
3. trochlear notch of ulna
Which one is smaller capitulum or trochlea - ANSWER:capitulum
Which one of the three concentric arcs is the smallest? - ANSWER:Trochlear sulcus
Shoulder the sea between 2 nations
mandible
elbow - ANSWER:coracoid
coronoid
coronoid
Head of the radius sits lower than the ulna true or false - ANSWER:true
the capitulum is of which bone - ANSWER:humerus
the capitulum is on which side of the humerus - ANSWER:lateral
Elbow fat pads and stripes demonstrates - ANSWER:- displacement
- disease
- injury
The humerus is the largest and longest bone in the upper extremity true or false -
ANSWER:true
Elbow joint - ANSWER:Elbow joint
- Ginglymus (hinge)
- flexion and extension
Proximal radioulnar joint
- Trochidal (pivot) type
- rotational
Synovial (diarthrodial) which mean freely moveable
Greater tubercle (tuberosity) - ANSWER:- muscles attach (supraspinatus and pec
major)
- proximal humerus
Shoulder Joint - ANSWER:- proximal humerus
- scapulae
Intertubular groove (bicipital groove) - ANSWER:- between greater and lesser
tubercle
surgical neck - ANSWER:common fracture site of humerus
, head of the humerus - ANSWER:
Anatomic neck - ANSWER:it's higher than surgical neck (A before S)
Lesser tubercle (tuberosity) - ANSWER:The process directly below the anatomic neck
on the anterior surface
Deltoid Tuberosity - ANSWER:- rough raised triangle
- muscle attachment of the deltoid
body (shaft) of humerus - ANSWER:
clavicle medial end - ANSWER:- sternoclavicular jt
- sternal extremity
clavicle lateral end - ANSWER:- also called the acromial extermity
- AC jt
What is the clavicle? - ANSWER:Long bone that is double curved
Female: Shorter and less curved
Male: Thicker and more curved
How do you know in a film if that its AP External Rotation of the Shoulder? -
ANSWER:profiles the greater tubercle
- the epicondyles are parallel (anatomical position) to make the greater tubercle in
profile
Bony Processes of the clavicle - ANSWER:- Sternal end (medial extremity)
- Acromial end (lateral extremity)
- Shaft or Body
What are the 3 borders of the scapula? - ANSWER:superior, medial (vertebral),
lateral (axillary)
Lateral angle (head of scapula) is the... - ANSWER:thickest part and ends laterally in a
shallow depression called the glenoid cavity (fossa)
Name the 3 angles of the scapula - ANSWER:lateral, superior, inferior
coracoid process is beneath the __________ and anterior to the ____________ -
ANSWER:clavicle
scapulae
costal surface (anterior) subscapular fossa - ANSWER:What is G?
supraspinous fossa (inferior) and infraspinous fossa - ANSWER:surfaces for muscle
attachment
