Bontrager Workbook: Chapter 5-Humerus and Shoulder Girdle

Bontrager Workbook: Chapter 5-Humerus and Shoulder Girdle The shoulder girdle consists of 1. proximal humerus 2. scapula 3. clavicle The three aspects of the clavicle are the: 1. sternal extremity 2. body/shaft 3. acromial extremity The ___(male/female) clavicle tends to be thicker and more curved in shape. male The three angles of the scapula: 1. lateral angle 2. superior angle 3. inferior angle The anterior surface of the scapula is referred to as the ___ surface. costal What is the anatomic name for armpit? axilla What are the names of the two fossae located on the posterior scapula? 1. infraspinous fossa 2. supraspinous fossa All of the joints of the shoulder girdle are classified as being: synovial (diarthrodial) List the movement types for the following joints: 1. Scapulohumeral 2. Sternoclavicular 3. Acromioclavicular 1. Spheroidal 2. plane 3. plane location: Coracoid process Crest of spine Scapula location: Acromial extermity Clavicle location: Greater tubercle Intertubercular groove Surgical neck Proximal humerus location: Coronoid process Condylar process Not a part of the shoulder girdle True/False The use of a grid is not required for shoulder studies that measure less than 10cm. True True/False The kV range for adult shoulder projections is between 80 and 90 kV for analog and 100 to 110 kV for digital imaging systems False True/False Low mA with short exposure times should be used for adult shoulder studies False True/False Large focal spot setting should be selected for most adult shoulder studies. False True/False A high-speed screen-IR system is recommended for analog shoulder studies when using a grid. True True/False A 72in SID is recommended for most shoulder girdle studies False True/False The use of contact shields over the breast, lung, and thyroid regions is recommended for most shoulder projections True Which one of the following kV ranges should be used for a shoulder series on an average adult? a. 70-80 kV b. 55-60 kV c. 80-90 kV d. 65-75 kV a. 70-80 kV If physical immobilization is required, which individual should be asked to restrain a child for a shoulder series? a. Parent or guardian b. Radiologic technologist c. Radiography student d. Nurse aide a. Parent or guardian True/False CT arthography of the shoulder joint often requires the use of iodinated contrast media injected into the joint space True True/False MRI is an excellent modality for demonstrating bony injuries of the shoulder girdle. False True/False Nuclear medicine bone scans can demonstrate signs of osteomyelitis. True True/False Radiography is more sensitive than nuclear medicine for demonstrated physiologic aspects of the shoulder girdle False True/False Ultrasound can provide a functional (dynamic) evolution of joint movement that MRI cannot.
