The surgeon will evaluate the tailbone’s curve to determine if the AxiaLIF approach can be used. This requires a standing x-ray of the lumbar spine, sacrum, and coccyx. MRI or CT will help identify any anomalies in the trajectory. AxiaLIF fusion may be helpful in treating: Degenerative ...
The New York criterion of pain in the (dorso) lumbar spine lacks specificity, and the chest expansion criterion is too insensitive. The Rome criterion of low back pain for more than 3 months is very useful. Our study showed the clinical history screening test for AS to be moderately ...
MRIneural networksUnderstanding the axial lumbar spine anatomy, including knowledge of the relationship between the lumbar spine level and other paraspinal structures, is important for diagnosing and treating diseases. The purpose of this study was to validate the accuracy of a convolutional neural ...
The authors describe the technique of transverse axial tomography of the spine and give a detailed description of the axial anatomy of the normal lumbar spine from L-4 to the sacrum. They demonstrate a specific repetitive pattern of intraosseous and articular segments, and stress the importance of...
Axial-Loaded MRI Using a SpineMAC Device to Show Narrowing of Dural Sac and Disc Height in Lumbar Spinal Stenosis Background: A lumbosacral spinal compression device has been developed by the authors (SpineMAC) to simulate normal weight-bearing by axial-loading of the ... Witaya SungkaratJira...
The cervical spine is important to consider in positioning the head in space. The dominant motion in the lower cervical spine is flexion-extension, but the cervical spine's anatomy permits a fair amount of motion in all planes. In high-speed injuries, the head can act as a significant lever...
MURCS Shortened and fused vertebrae of the cervical and thoracic spine Muellerian duct aplasia, unilateral renal aplasia 601076 VATER Hemi-vertebrae and fused vertebrae, usually thoracic and lumbar and includes cases of lumbar-sacral agenesis Anal atresia, tracheo-esophageal fistula with esophageal atresia...
Quantification of structural spinal AS changes is performed by the modified Stokes AS Spine Score (mSASSS), which evaluates lateral cervical and lumbar radiographs. Two years was identified as the shortest possible follow-up time based on the reliability and sensitivity to change of the mSASSS. A ...
systematically reviewed 14,570 pedicle screws inserted in the thoracic and lumbar spine of 1,666 patients with adolescent idiopathic scoliosis [12]. They found that the overall rate of screw malposition was 0.2% with 6 of 8,147 screws (0.07%) abutting the aorta in the group of studies that...
In the erect human spine, all vertebrae are exposed to axial compression, but in addition, certain areas are subject to posteriorly directed shear loads (arrows in red), others to anterior shear loads (green arrows), depending on their spatial orientation. Posteriorly directed shear loads render ...
