Flashcards
Humerus and Shoulder Girdle Radiologic Positioning
Cards in this deck (20)
- 1Why 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.
- 2Trauma vs routineRoutine: 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 - 3What procedures can be used to identify dislocation/displaced fracture?Shoulder Y (PA Oblique)
Transthoracic lateral
Garth Method - 4Anterior Glenohumeral DislocationGlenohumeral joint is widened
- 5Posterior Dislocationhumeral 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' - 6Radiographic exams for AC dislocationUnilateral/Bilateral
Erect AC joints - 7Radiographic exams for AC separationUnilateral or bilateral
Erect AC joints (with and without weights)
Zanca method - 8AC joint separation pathologyAsymmetric widening of AC joint compared with contralateral (opposite) side
- 9Shoulder dislocation pathologySeparation between humeral head and glenoid cavity
- 10Rotator cuff injury pathologyPartial or complete tear in musculature
- 11Frozen shoulder pathologyPossible calcification or other joint space abnormalities
- 12Fracture humerusHill-Sachs: Compression fracture and possible anterior dislocation of humeral head
- 13A 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
- 14Which type of injury must be ruled out before the weight-bearing phase of an AC joint study?Fractured clavicle
- 15A 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
- 16A 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
- 17Rotator cuff radiograph examMRI or sonography
- 18Frozen shoulder radiograph examAP rotation shoulder and PA oblique (Scapular Y-Neer method) projection shoulder
- 19Hill-Sachs radiograph examAP internal rotation and transaxillary with exaggerated external rotation
- 20A 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
