The receptionist told me, after checking my file at my request since I was there a few months after the x-rays for a different test, that it wasnt something the radiologist measured and wasnt something that they do there. when implementing horizontal beam technique, ensure the distal upper limbs are not overlying the region of interest. Honestly I dont know why they accepted the request for flexion-extension x-rays if it isnt something that they assess at that office.Spinal curvature in the AP projection will determine if a right lateral or a left lateral is performed. Lumbar X-rays should include a full series with standing or weight-bearing views: standing anterior-posterior (AP) pelvis and lateral flexion-extension views. Noninvasive three-dimensional analysis of cervical spine motion in normal subjects. It should be noted that patients with normal alignment in the neutral position may demonstrate spondylolisthesis on flexion or extension (Fig. in the lateral decubitus position, position the patient so that the humeri are extended 90 degrees to the thorax, with the elbows flexed so that the forearms are parallel to the thorax. X-rays during flexion and extension of the cervical spine. concluded that between flexion and extension, the upper limit of normal total parallel excursion is 4 mm and the upper limit of normal angular change is 10°.all imaging of patients with suspected spinal injury must occur in the supine position without moving the patient.ideally, spinal imaging should be taken erect in the setting of non-trauma to give a functional overview of the lumbar spine.Patients will be referred for cervical spine flexion and extension radiography because of trauma to the cervical spine. cervical vertebrae during spontaneous neck flexion extension. These views are specialized projections to provide functional tests 1 of lumbar spine instability, often in the context of spondylolisthesis. Flexion and extension cervical spine radiography can be self defeating in the acute setting. X-ray fluoroscopy allows time-continuous screening of cervical spine during patients spontaneous.
