**Case Study: Shoulder Injury in a 21-year-old Football Player**A 21-year-old patient presents to the clinic after a post-blunt shoulder injury while playing football. During the physical exam, there is tenderness to palpation and mild deformity at the lateral end of the clavicle where it meets the scapula.**Question:**Based on these physical exam findings, which of the following is the most likely anatomic structure injured?**Answer Options:**A. Subscapular bursa B. Glenohumeral ligaments C. Acromioclavicular joint D. Superior glenohumeral ligament ---**Analysis:**This question focuses on identifying the injured structure based on symptoms and location of tenderness. The physical exam findings suggest a focus on the lateral end of the clavicle, indicating a possible injury to the acromioclavicular joint.

The shoulder is made up of three bones: the scapula, clavicle and humerus. Movement of shoulder occurs because of two joints called the acromioclavicular joint and the glenohumeral joint.The lateral end of the clavicle articulates with the projection on the scapula called the acromion forming the acromio - clavicular joint. It is a type of Synovial Joint. It can be very painful when there is a shoulder injury, though the joint shows little or no movement. So this 21 year old patient must have hurt his acromio clavicular joint present in the shoulder during the post blunt shoulder injury while playing a football.Explanation for wrong answers- Subscapular bursa is a pouch-like structure that remains attached to the scapular neck and the adjacent part of the joint capsule.Glenohumerus ligament connects the glenoid fossa to the humerus.Superior glenohumerus ligament is not hurt in this case. Acromioclavicular joint
