Q

How can you determine if you are examining the left or right clavicle?

A
  1. Acromial end is more rounded and blunt than the sternal end
  2. The sternal end is wider than the acromial end
  3. Once you determine the above two, check for the superior surface (which is smooth)

Q

How can you determine if you are examining the left or right humerus?

A
  1. Identify the greater and lesser tubercles of the proximal humerus to help determine the posterior aspect of the humerus
  2. Locate the capitulum and trochlea to confirm the anterior and posterior aspect
  3. Identify the medial epicondyle of the distal humerus since it is larger and more prominent than the lateral epicondyle

Q

Why is an anterior dislocation more likely than a posterior dislocation?

A

Majority of the muscles pull the shoulder forward anteriorly, making it more susceptible for anterior dislocations.
