  4. AP Shoulder External Rotation Non trauma: Basic * Film Size: 10x12 in.(24x30 cm).Crosswise or lengthwise. * SHIELDING: pelvic area. Patient Position: May be taken erect or supine.(Erect is usually less painful for patient if condition allows). Rotate body slightly toward affected side to place shoulder in contact with film holder or table – top. Part Position: Position patient to center scapulohumeral joint to centered of IR. Abduct extended arm slightly , then externally rotate arm ( supinate hand ) until epicondyles of distal humerus are parallel to film. Distance: 100 cm or 40 in. C R: perpendicular to film. CP: (1 in ( 2.5cm ) inferior to Coracoid process). Collimation: collimate on four sides to area of interest. NB/ (suspend respiration during Exposure )to reduce movement and tension

  6. AP Shoulder: Internal Rotation Non trauma: Basic Film Size: 10x12 in. (24x30 cm).Crosswise or lengthwise . SHIELDING: pelvic area. Patient Position: May be taken erect or supine.( Erect is usually less painful for patient if condition allows). Rotate body slightly toward affected side to place shoulder in contact with film holder or table – top. Part Position: Position patient to center scapulohumeral joint to centered of IR. Abduct extended arm slightly , then internally rotate arm ( pronate hand ) until epicondyles of distal humerus are perpendicular to film. Distance: 100 cm or 40 in. C R: perpendicular to film. CP: (1 in ( 2.5cm ) inferior to Coracoid process). Collimation: collimate on four sides to area of interest. NB/ (suspend respiration during Exposure )to reduce movement and tension

  8. AP neutral Rotation: Shoulder(trauma): Basic Film Size: 10x12 in. (24x30 cm). Crosswise or lengthwise . SHIELDING: pelvic area. Patient Position: May be taken erect or supine.( Erect is usually less painful for patient if condition allows)Rotate body slightly toward affected side to place shoulder in contact with film holder or table – top. Part Position: Position patient to center scapulohumeral joint to centered of IR. Place patients arm at side in neutral rotation.(epicondyles are generally approximately 45 degree to plane of IR or film. Distance: 100 cm or 40 in. CR : perpendicular to film. C P: To mid scapulohumeral joint (3/4 in (2 cm ) inferior and slightly lateral to the Coracoid process). Collimation: collimate on four sides to area of interest. NB/ (suspend respiration during Exposure )to reduce movement and tension .

  9. AP neutral Rotation: Shoulder(trauma): Basic Structure shown: the proximal one third of the Humerus upper scapula , and lateral of 2/3 of theclavicleis shown , including the relationship of the Humeral head to the glenoid cavity.

  10. Inferosuperior Shoulder (Axial)Lawrence Method(Special) Non-trauma case Film Size: 8x10 in. (18x24 cm)Crosswise. SHIELDING: pelvic area. Patient Position: Ptsupine Shoulder raised 5 cm from tabletop by placing support under arm and shoulder. Head rotated toward opposite side. Part Position: Arm abducted 90. With external rotation (palm up) , Vertical cassette placed close to the neck. Distance: 100 cm or 40 in. C R: Horizontal 25 - 30 medially to film center. C P: Humeral head (axilla). Collimation: collimate on four sides to area of interest. NB/ (suspend respiration during Exposure )to reduce movement and tension

  11. Inferosuperior Shoulder (Axial)Lawrence Method(Special) coracoid process Structure shown: lateral view of proximal Humerus in relationship to the scapula cavity is shown coracoid process Of scapula , Lesser tubercle of humerus is shown , the spin of the scapula will be seen on edge below the scapulohumeral joint Acromion Glenoid fossa spin of the scapula

  12. Inferosuperior Shoulder (Axial)West point Method(Special) Non-trauma case Film Size: 8x10 in. (18x24 cm). Crosswise. SHIELDING: pelvic area. Patient Position: Patient prone, head rotated away from affected side, film held vertically against superior surface of the shoulder. Part Position: affected shoulder raised 8 cm, affected arm abducted 90 deg., elbow flexed with forearm hanging freely over table side. Distance: 100 cm or 40 in. C R: 25 anterior( down from horizontal ) and then 25 medially to film center. C P: Mid scapulohumeral joint. Collimation:collimate on four sides to area of interest. NB/ (suspend respiration during Exposure ) to reduce movement and tension

  13. Inferosuperior Shoulder (Axial)West point Method(Special) Structure shown: An axial view of the shoulder girdle is shown .The anteroinferior aspect of glenoid rim is well demonstrated, humeral head is seen free of coracoid superimposition. Acromion scapulohumeral joint Lesser tubercle

  14. APO ( Glenoid Cavity) GrasheyNON trauma Special Film Size: 8x10 in. (18x24 cm). Crosswise SHIELDING: pelvic area. Patient Position: Patient erect or supine ,body rotated 35 to 45 toward affected side . Part Position: Place support under elevated shoulder and hip (in the supine) Arm abducted slightly in a neutral position. Top of the cassette 2 in (5 cm) above shoulder. Distance: 100 cm or 40 in. C R: perpendicular to film. CP: Scapulohumeral joint 2in (5cm) inferior and medial to Superolateralborder of shoulder. Collimation: collimate on four sides to area of interest. NB/ (suspend respiration during Exposure )to reduce movement and tension.

  15. APO ( Glenoid Cavity) GrasheyNON trauma Special Acromion coracoid process humeral head Structure shown: glenoid cavity should be seen in profile without superimposition , humeral head. glenoid cavity

  16. Tangential ( Intertubercular Groove) NON trauma Fisk Method(Special) Film Size : HD 8x10 in. (18x24 cm). Crosswise SHIELDING: place lead shield over pelvic area. Body and Part position Patient standing, leaning over end of table elbow flexed and posterior surface of forearm resting on table, hand supinated holding cassette. patient leans forward to place humerus 10 – 15 from vertical. CR: 90 to film center. CP: directed to the groove at mid anterior margin of humeral head . Collimation: collimate on four sides to area of interest. NB/ (suspend respiration during Exposure )to reduce movement and tension.

  17. Tangential ( Intertubercular Groove) NON trauma Fisk Method(Special) intertuberclar bicipital groove. Structure shown: the anterior margin of humeral head is seen in profile . The humeral tubercles and intertuberclar groove seen in profile Lesser tubercle greater tubercle coracoid process Lat end clavicle

  18. Transthoracic Lateral projection : Lawrence MethodBasicShoulder ( trauma). Film Size: 10x12 in. (24x30 cm) lengthwise. SHIELDING: pelvic area. Patient Position: May be taken erect or supine.( Erect is usually less painful for patient if condition allows). Place patient in lateral position with side of interest against cassette. Part Position: Place affected arm at patients side in neutral rotation drop shoulder if possible. Raise opposite arm and place hand over top of the head elevate shoulder as much As possible To prevent superimposing affected shoulder. Ensure that thorax is in true lateral position or with slightly anterior rotation of unaffected shoulder to minimize superimposition of hummers by thorax vertebrae. Distance: 100 cm or 40 in. CR perpendicular to film. CP: directed through thorax to surgical neck. Collimation: collimate on four sides to area of interest. NB/ breathing technique is preferred if patient can co-operate Pt should be asked to gently breathe short, shallow breaths without moving affected arm or shoulder. (this will best visualize proximal hummers by blurring out ribs and lung structure.)

  19. Structure shown: lat view of the proximal half of the humerus and glenoihumeral joint should be visualized through the thorax without superimposition of the opposite shoulder.
