| Question | Answer |
| Why do we need 2 trauma shoulder? | Patient can't move/rotate arm; helps in visualizing potential fractures or dislocations to the proximal humerus and shoulder girdle in a trauma setting. |
| Trauma vs routine | Routine: we are rotating (internal/external) the patient's arm; epicondyles parallel to IR Trauma: no rotation of arm involved; epicondyles are 45 to plane of IR |
| What procedures can be used to identify dislocation/displaced fracture? | Shoulder Y (PA Oblique) Transthoracic lateral Garth Method |
| Anterior Glenohumeral Dislocation | Glenohumeral joint is widened |
| Posterior Dislocation | humeral head no longer overlies the glenoid humerus is held in internal rotation and the contour of the humeral head is said to resemble a 'light bulb' |
| Radiographic exams for AC dislocation | Unilateral/Bilateral Erect AC joints |
| Radiographic exams for AC separation | Unilateral or bilateral Erect AC joints (with and without weights) Zanca method |
| AC joint separation pathology | Asymmetric widening of AC joint compared with contralateral (opposite) side |
| Shoulder dislocation pathology | Separation between humeral head and glenoid cavity |
| Rotator cuff injury pathology | Partial or complete tear in musculature |
| Frozen shoulder pathology | Possible calcification or other joint space abnormalities |
| Fracture humerus | Hill-Sachs: Compression fracture and possible anterior dislocation of humeral head |
| A pt enters the ER with a definite fracture to the midhumerus. Due to other trauma the patient is unable to stand. Which lateral position would demonstrate the entire humerus? | Transthoracic lateral projections for humerus |
| Which type of injury must be ruled out before the weight-bearing phase of an AC joint study? | Fractured clavicle |
| A pt enteres ER with a proximal and midhumeral fracture. the patient is in extreme pain, which projection routines would demonstrate the entire humerus without excessive movement of the limb? | AP and transthoracic lateral of humerus |
| A patient comes to the ER with a possible right AC joint separation. Right clavicle and AC joint exams are ordered. The clavicle is taken first, and a small linear fracture of the midshaft of the clavicle is discovered. What should the tech do in this situation? | Consult with the ER physician before continuing with the AC joint study |
| Rotator cuff radiograph exam | MRI or sonography |
| Frozen shoulder radiograph exam | AP rotation shoulder and PA oblique (Scapular Y-Neer method) projection shoulder |
| Hill-Sachs radiograph exam | AP internal rotation and transaxillary with exaggerated external rotation |
| A patient with a possible acromioclavicular seperation enters the ER room. Which routines should be used? | Acromioclavicular joint series: non weight bearing and weight bearing projection |
