Trochlea and ulna (2 pt)
7. Why is critical to diagnose a medial epicondyle entrapment? Entrapped medial epicondyle will fuse to the ulna within a few weeks resulting in permanent disability (1 pt)
8. Fracture of this is the most common bone fractured in the elbow of adults? What are the 2 most common types of this fracture? Proximal radius - 1. Single longitudinal fractue in proxmal articular surface of the radial head; 2. Impaction of an intact radial head into the radial neck (3 points)

Bonus - The real answer is all or none - whichever you prefer. As a "Gen X-er", I find the whole everyone in a 20 year span to be all in one type of mindset or anything as a little annoying. My parents are Boomers but they aren't anything like traditional boomers. I never felt that the media portrayal of my generation to make sense and now we are simply forgotten which is fine. There may be some generalities or stereotypes but we are all individuals and different. I am Hayekian in my philosophy - no simple explanation can explain all things. Occam's razor works well for diseases but not for generational descriptors as a predictor of a single individual. I enjoyed your answers.
