Immobilisation in Australian paediatric medical imaging: A pilot study. X-ray measurements of the hip joints of children, with special reference to the acetabular index, suggest that the upper standard deviation of normal comprises the borderline to a critical zone where extreme values of normal and pathologic hips were found together. Poor Utility of Gonadal Shielding for Pediatric Pelvic Radiographs. Gonad Shielding during Pelvic Radiography: A Systematic Review and Meta-analysis. Karami V, Zabihzadeh M, Shams N, Saki Malehi A. bilateral examination allows for better visualization of the hip joints and femoral neck. lataral projection to aid and diagnose femoroacetabular impingement (FAI) due to its increased sensitivity for detecting femoral head-neck asphericity. doi:10.1016/j.clinimag.2008.09.013 - Pubmedģ. the ideal projection for bilateral hip or femur trauma Additional projections. What causes the "wet diaper" artifact? computed tomography and magnetic resonance observations. Other departments will make use of restraint devices, there is debate around the use of 'restraint' and if it fits the category of 'immobilisation' 6.ġ. A radiographer or parent being in the room with the patient holding them still has been cited as a commonly used technique 5 in the Australian context. Therefore, immobilisation techniques will vary from department to department. turning around to look at their parent)Īs children are lying supine for the examination, distraction techniques may prove difficult. ensure the child’s distraction lies directly above or in front of them so they are not rotating their body to look at it (e.g.using the swaddling technique wrap the child in a blanket to promote comfort and sleep.distract the patient with toys, games and/or conversation Fig 1 Anteroposterior pelvis x ray in a 9 year old girl with right hip pain.To overcome this, a variety of techniques can be used: rotation of the pelvis due to patient motion.The major difficulty in paediatric pelvis radiography relates to: However, recent studies no longer recommend the use of gonadal shielding for paediatric pelvis examinations 3,4. When placed incorrectly, additional repeats will be required, thereby increasing the radiation dose to the patient. The use of gonadal shielding will vary from department to department. Brady JM, Dulligan PJJ, Fett HCJ, Gallagher TF et al (1953) Horizontal lateral roentgenography of the hip in children a. Excessive external rotation of a normal hip can also break Shenton’s line without subluxation of the femoral head. Wet nappies are also known to create artifact on the radiograph, therefore should be removed 2. It is performed with the patient supine on the X-ray table with the hip externally rotated and. Patients should remove any clothing from the waist down especially baby rompers as these often have metal buttons. hip surveillance in cerebral palsy patients.developmental dysplasia of the hip (DDH).Performing pelvis radiography on paediatric patients can be for a number of indications 1: ![]()
