REFERENCE: Merrill’s Atlas of Radiographic Positioning & Procedures, 10th Edition;


Ballinger Vol. 1, 10th Edition


I. LEARNING OBJECTIVES


By the end of this laboratory activity, the students should be able to:


1. 2. 3. 4. Identify and position patients correctly for shoulder girdle radiographic procedures.


Perform standard projections of the clavicle, scapula, shoulder joint, and


acromioclavicular (AC) joints.


Evaluate radiographic images based on positioning and anatomical criteria.


Apply radiation protection and positioning principles in shoulder girdle imaging.


II. CONTENT OUTLINE


 Basic Anatomy: Clavicle, scapula, shoulder joint, AC joints


 Radiographic Projections:


o Clavicle: AP, AP Axial


o Scapula: AP, Lateral


o Shoulder Joint: AP (Internal & External Rotation), AP Oblique (Grashey), PA


Oblique (Y-View), Inferosuperior Axial (Lawrence Method)


o AC Joints: AP with and without weights (bilateral)


 Patient Preparation and Positioning


 Central Ray (CR) and Collimation


 Image Evaluation Criteria


III. MATERIALS AND EQUIPMENT


 Digital X-ray unit


 Radiographic table / upright BuckySouthwestern University – PHINMA

LABORATORY ACTIVITY: Shoulder Girdle


 Imaging receptor (IR)


 Lead aprons / thyroid shields


 Positioning aids (sponges, sandbags)


 Markers (R/L indicators)


 Weights (for AC joint study)


IV. LABORATORY ACTIVITY


Instructions:


1. 2. 3. 4. Divide into pairs. One acts as the patient, the other as the radiologic technologist.


Practice positioning for each required projection of the shoulder girdle.


Ensure correct alignment, CR entry, SID, and collimation.


Simulate exposure and label anatomical landmarks.
