Disorders of the Shoulder (PEARLS) - Shoulder Fractures/dislocations and Soft tissue injuries of the shoulder (Smarty PANCE) Exam Questions and Answers | Graded A+ The shoulder is made up of what three bones? The shoulder is made up of three bones: ● Scapula (shoulder blade) ● Clavicle (collar bone) ● Humerus (arm bone) These bones are joined together by soft tissues (ligaments, tendons, muscles, and joint capsule) to form a platform for the arm to work. The shoulder is made up of what three joints? The shoulder is made up of three joints: ● Glenohumeral joint ● Acromioclavicular joint ● Sternoclavicular joint What structures are commonly fractured in the shoulder? Fractures commonly involve the clavicle (collar bone), proximal humerus (top of the upper arm bone), and scapula (shoulder blade) Describe the three type of dislocations seen in the shoulder? Dislocations occur when the bones on opposite sides of a joint do not line up. Dislocations can involve any of three different joints. ● A dislocation of the acromioclavicular joint is called a "separated shoulder." ● A dislocation of the sternoclavicular joint interrupts the connection between the clavicle and the breastbone (sternum) ● The glenohumeral joint (the ball and socket joint of the shoulder) can be dislocated toward the front (anteriorly) or toward the back (posteriorly). What are the common causes of fractures of the clavicle or the proximal humerus? Fractures of the clavicle or the proximal humerus can be caused by a direct blow to the area from a fall, collision, sports injury, or motor vehicle accident. What are the common causes of fractures of the scapula? Because the scapula is protected by the chest and surrounding muscles, it is not easily fractured. Therefore, fractures of the scapula are usually caused by high-energy trauma, such as a high-speed motor vehicle accident (MVA). Scapula fractures are often associated with injuries to the chest. What is the most common location of clavicle fracture? Middle 1/3 of clavicle and tend to have an upward displacement What are the specific findings of a clavicle fracture? The specific findings of a clavicle fracture are erythema and deformity of the clavicle ● Tenderness to palpation - worse with passive and active movement. ● Tenting of skin overlying fracture
