3. The hip joint is synovial joint formed by the articulation of the rounded head of the femur and the cup-like acetabulum of the pelvis. It forms the primary connection between the bones of the lower limb and the axial skeleton of trunk and pelvis. INTRODUCTION FOR HIP JOINT

6. ANTERIO-POSTERIOR VIEW-BOTH HIPS ANTERIO –POSTERIOR-SINGLE HIP BASIC VIEWS OF HIP JOINT

7. INTRODUCTION: The anterio-posterior(AP)projection is a general image used as a first assessment of the pelvic bones and hip joint PATIENT POSITION: Patient supine on the table, arms at side or across upper chest Cushion for patients head Internally rotate foot and leg 15° to 20° (do not attempt to internally rotate if fracture or dislocation suspected), sandbags may be used to maintain this position. ANTERO-POSTERIOR VIEW-BOTH HIPS

8. IR SIZE & ORIENTATION :14x17 inches (landscape) GRID : Yes EXPOSURE :70 kVp:20 mAs FFD / SID: 100cm CENTRAL RAY: The collimated vertical beam is centred over the midline midway between the upper border of the symphysis pubis and ASIS for the pelvis. TECHINICAL DETAILS

9. RADIOGRAPHIC ANATOMY OF PELVIS AP WITH BOTH HIPS

10. INTRODUCTION: The (AP)pelvis view is part of a pelvic series examining the illiac crest,sacrum proximal. Patient is supine lower limbs are internaly rotated 15-25 degree from the hip PATIENT POSITION : The patient is positioned as described for the basic pelvics and basic bilateral hip projection. To avoid pelvic rotation the anterior superior iliac spines must be equidistant from the tabletop The affected limb is internally rotated to bring the neck of femur parallel to the tabletop,supported by sandbags if necessary ANTERIO-POSTERIOR-SINGLE HIP

11. IR SIZE&ORIENTATION: 14x 17 inches( Landscape) GRID : Yes FFD/SID: 100cm EXPOSURE: 70 kv;20mAs CENTRAL RAY: The collimated vertical beam is centered 2.5cm distally along the perpendicular bisector of a line joining the ASIS and the symphysis pubis over the femoral pubis. TECHINICAL DETAILS

13. FROG LEG –VIEW CROSS -TABLE LATERAL VIEW FALSE-PROFILE VIEW ANTERIOR (or)POSTERIOR OBLIQUE VIEW(JUDET VIEW) SPECIAL VIEWS OF HIP JOINT

14. FROG LEG VIEW

15. This projection is useful for demonstration of a non-trauma hip or developmental dysplasia of hip(DDH)and congenital hip dislocation(CHD ) INTRODUCTION

16. PATIENT POSITION : The knee joint its flexed 30-40 degree in a supine position.while the hip externally rotated by 45 degree so that the image is taken toward the middle of line conecting the upper symphysis pubis. FROG LEG VIEW

17. X -ray image of frog leg view

18. IR SIZE & ORIENTATION :14X17inches(Landscape) GRID: Yes FFD/SID :100cm EXPOSURE : 80kVp,12 mAs CENTER RAY: 3 inches below the level of ASIS and minimum 1 inches symphysis pubis. TECHINICAL DETAILS

19. INTRODUCTION : Our study shows that cross table radiography provides acceptable information for clinical use, but has limited use for precise analysis of acetabular cup version. CROSS-TABLE LATERAL VIEW

20. Positioning for the cross table lateral view. a lower extremity is internally rotated by 15°-20° in supine position and then the hip an knee joints on the other side are flexed to prevent interference in radiographic projection. Cassette is positioned on the side of the hip at right angle relative to incidence angle there by projection toward the groin region at 35°-45° of incidence parallel to longitudinal axis of femur. PATIENT POSITION

22. IR SIZE & ORIENTATION: 14x17 inches,Landscape EXPOSURE: 80 kVp:40 mAs GRID : Yes FFD / SID: 100cm CENTRAL RAY: CR perpendicular to long axis of femoral neck TECHINICAL DETAILS

23. INTRODUCTION: The flash profile radiographic view of the hip has traditionally been used to measure acetabular coverage in the setting of femoroacetabular impigment but some belive it can also be useful in assessing the morphology of the femoral head-neck junction. FLASH PROFILE VIEW

24. Patient in orthostatic position. Affected hip against the cassette. Pelvis rotated 65°anteriorly in relation to the cassete. The femur of the affected side should be perpenducular to the floor. The patient should not be leaning and the knee should be locked on the affected side. The degree in oblique will vary from patient to patient. The foot of unaffected side should be abducted and/or perpendicular to the image receptor. PATIENT POSITION

25. X-ray image of flash profile view

26. IR SIZE & ORINTATION: 14X17 inches(portrait) GRID: yes FFD/SID: 100cm EXPOSURE: 70Kvp;20mAs CENTERAL RAY: should be exit the hip of interest. standing behind the x-ray tube to assess centering. too much collimation light seen lateral to affected side will indicate off centering . TECHINICAL DETAILS

27. INTRODUCTION: Judet’s views are standard radiographic projections which are employed in patients with acetabulum fractures. This projection may be used to assess the acetabulum when a fracture is suspected JUDET’S VIEW

28. ILIAC OBLIQUE Patient is supine,the unaffected side is rotated roughly 45°anterior,generally aided with a 45° sponge.it is advisable the patient is central on the table and at no risk of over rolling. OBTURATOR OBLIQUE Patient is supine,the a affected side is rotated rougly 45° anterior,generally aided with a 45°sponge.ensure the patient is central on the table and at on risk of over rolling. PATIENT POSITION

30. IR SIZE & ORIENTATION :14x17inches(Landscape) EXPOSURE : 70-80 KvP; 10-20 mAs FFD/SID :100cm GRID :Yes CENTRAL RAY : ILIAC OBLIQUE : 5 cm distal and 5 cm medial of the ASIS closest to the image receptor. OBTURATOR OBLIQUE : 5cm distal and 5 cm medial of the ASIS that is rolled up anterior to the image receptor TECHINICAL DETAILS
