Q

What injury is the Glenohumeral Joint susceptible to?

Why?

What most commonly occurs due to the presence of the Coracoacromial Arch?

A

Dislocation

due to mobility and relative instability (shalow Glenoid Cavity)

Dislocation most commonly occurs anteriorly and inferiorly

CN: The Glenohumeral Joint is susceptible to dislocation due to its mobility and relative instability. Due to the presence of the Coracoacromial Arch dislocation of the Glenohumeral Joint most commonly occurs anteriorly or inferiorly.

Q

What has the nicknames Students Elbow, Dart Throwers Elbow, and Miners Elbow?

A

Inflammation of Subcutaneous Olecranon Bursa
