How do you diagnose a Supracondylar Fracture
Trace the anterior humeral line down through the capitulum. It should not pass through the anterior 1/3rd of the capitulum. If it does, this is indicative of a supracondyler fracture. See the attached image. Also notice the sign of the sail and the olecranon fat pad
What causes a hill-sachs fracture and what does it look like? What causes a bankart lesion?
When the shoulder is dislocated, the glenoid gets shoved into the humeral head and causes a compression fracture. A Bankart lesion is when the labrum detaches and takes a chunck of bone with it. They both look like this:
What does the ligh bulb sign indicate?
A posterior shoulder dislocation. Notice there is no overlap between the humeral head and the glenoid and the greater tuberosity is not visable on the AP external view
What are the thee type of anterior glenohumeral dislocations? Which one is the most common?
On which view can you see the greater tuberosity of the humerus?
AP external rotation (walking stick view)
What do the AP internal and external views have in common?
The humeral head overlaps the glenoid
How do you diagnose an elbow effusion?
The sign of the sail on the coronoid fossa and any visiable fat pad on the olecranon fossa
On which view can you not see the greater tuberosity of the humerus?
AP internal rotation
What are the 6 femoral neck fractures?
