MSK Flashcards
How are most joints imaged?
AP and lateral, sometimes oblique as well
How is the shoulder imaged?
- AP
- lateral (Y-view of scapula)
- internal and external rotation
- axilalry lateral
- AP with craino-caudal downtilt
What does an IE AP film of the shoulder show?
posterolateral humeral head; can be fractured in dislocationss
What does an ER AP shoulder film show?
greater tubercle; can be fractured
What does the axillary film of the shoulder show?
- plate on top, beam inferior
- alignment of the glenoid-humeral head and AC joint
- coracoid fracture
Where are the secondary ossification centres in the shoulder?
- glenoid
- acromion (3)
- outer end of clavicle
- in addition to the greater and lesser tubercles and the humeral head
What views are taken of the elbow?
- AP
- lateral
- AP oblique
What ossification centre is visible in the elbow at 2 years?
capitulum
What ossification centres are visible in the elbow at 5 years?
- capitulum has fused to trochlea
- epiphyseal centre for the radial head
What ossification centres are visible in the elbow at 8 years?
- for the capitulum and lateral trochloea (large)
- small one for trochlea
- medial epicondyle
- radial head epiphysis has grown
What ossification centres are visible in the elbow at 10 years?
- capitulum and trochlea are fused to the humerus
- radial head is almost gused
- little one for medial epicondyle
What ossificiation centres are visible in the elbow at 13 years?
- medial epicondyle not quite fused
- radial head not quite fused
- olecranon not quite fused
When does the epiphyses for the capitulum and lateral trochlea appear?
