Hip joint xray normal4/14/2024 If in the first case the procedure lasts about 10 minutes, and the picture is taken on film, then in the second method the time is halved, and the image can be in two formats, including digital. The standardized radiography technique is little dependent on the method used - analog or digital. In addition, x-rays can be prescribed for pain in the hip joint in children of different ages. The main pathology is congenital dislocation of the hip. This means that the images obtained of all articular elements have no anatomical abnormalities, for more details see - Hip JointĪn X-ray of the hip joints in children is carried out according to strict indications - only after the child reaches nine months. If the above diseases and conditions are absent, the protocol (description) of the x-ray image will indicate that the x-ray is normal. In principle, the patient's complaints about the felt pain in the hip joint are considered sufficient reason for the appointment of radiography - to establish their exact cause. osteoarthritis, osteomyelitis and osteochondromatosis.coxitis (inflammation of the hip joint).arthritis, arthrosis of the hip joint, deforming arthrosis or coxarthrosis.juvenile epiphysiolitis of the femoral head.congenital dislocation or dysplasia of the hip joints.traumatic damage to the hip area, in particular, femoral neck fractures.The most common indications for X-ray diagnostics of the hip joints relate to: When the patient is properly positioned, as in Figure 2D, it is evident that coverage of the dorsal acetabular rim (white arrows) is similar on both sides.Directing the patient to radiography, a traumatologist, orthopedic surgeon, surgeon or rheumatologist are able to assess the state of structures of this bone joint. The dorsal acetabular rim (white arrows) appears to provide more coverage of the right femoral head and less coverage on the left side. Oblique positioning will result in false assessment of dorsal acetabular rim coverage of the femoral head, as shown in Figure 2C. Additionally, the left (down) ilium appears narrower. In this image, the right (up) obturator foramen is increased in width compared with the left. In Figure 2B, the right hemipelvis has been elevated from the imaging plate. The pelvis is rotated with the right hemipelvis farther away from the imaging plate. The right stifle should be moved axially (medially) so the femurs are parallel. The right femur/stifle should be further internally rotated (so the patella is more centrally located over the femur). In this example, there are multiple positioning errors. Pelvic radiographs must be assessed for adequate positioning and should be repeated if the pelvis is oblique, as in Figure 2A. Ensuring that both limbs are positioned similarly allows side-to-side comparisons. This can be useful when radiographic changes are equivocal. Figure 1C shows an example of the pelvis correctly positioned.Īltering the degree of limb extension or flexion and changing the degree of internal or external rotation can significantly affect the appearance of the femoral head and neck. Ideally, the sacrum, ilial wings, and entire 7th lumbar vertebra should be included in the image. Note the uniform and equal size of the obturator foramen on this well-positioned radiograph. In this image the femurs are parallel with each other and parallel with the imaging plate. If the stifles are kept internally rotated, the patella should be centrally located over the distal femurs, as seen in the normally positioned radiograph ( Figure 1B). The limbs are then extended, maintaining the internal rotation, until the femurs are parallel with the table. While in a flexed position, the limbs are internally rotated and abducted so that the stifles are almost touching. All but the pelvis and hindlimbs are within the trough. This view is best obtained with the dog placed in dorsal recumbency, which is done by using a foam positioning trough. Step-by-Step: Pelvic Radiography Positioningįigure 1A demonstrates the normal positioning for the ventrodorsal hip-extended view (the view that should be submitted to the Orthopedic Foundation for Animals).
